ASP.NET程序中常用的三十三種代碼

2010-08-28 10:48:18來(lái)源:西部e網(wǎng)作者:

    1. 打開新的窗口并傳送參數(shù):

  傳送參數(shù):

response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>")
  接收參數(shù):

string a = Request.QueryString("id");
string b = Request.QueryString("id1");

  2.為按鈕添加對(duì)話框

Button1.Attributes.Add("onclick","return confirm(’確認(rèn)?’)");
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}")

  3.刪除表格選定記錄

int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex];
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString()

  4.刪除表格記錄警告

private void DataGrid_ItemCreated(Object sender,DataGridItemEventArgs e)
{
 switch(e.Item.ItemType)
 {
  case ListItemType.Item :
  case ListItemType.AlternatingItem :
  case ListItemType.EditItem:
   TableCell myTableCell;
   myTableCell = e.Item.Cells[14];
   LinkButton myDeleteButton ;
   myDeleteButton = (LinkButton)myTableCell.Controls[0];
   myDeleteButton.Attributes.Add("onclick","return confirm(’您是否確定要?jiǎng)h除這條信息’);");
   break;
  default:
   break;
 }

}

  5.點(diǎn)擊表格行鏈接另一頁(yè)

private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
 //點(diǎn)擊表格打開
 if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
  e.Item.Attributes.Add("onclick","window.open(’Default.aspx?id=" + e.Item.Cells[0].Text + "’);");
}

  雙擊表格連接到另一頁(yè)

  在itemDataBind事件中

if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
 string OrderItemID =e.item.cells[1].Text;
 ...
 e.item.Attributes.Add("ondblclick", "location.href=’../ShippedGrid.aspx?id=" + OrderItemID + "’");
}

  雙擊表格打開新一頁(yè)

if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
 string OrderItemID =e.item.cells[1].Text;
 ...
 e.item.Attributes.Add("ondblclick", "open(’../ShippedGrid.aspx?id=" + OrderItemID + "’)");
}

6.表格超連接列傳遞參數(shù)

<asp:HyperLinkColumn Target="_blank" headertext="ID號(hào)" DataTextField="id" NavigateUrl="aaa.aspx?id=’
。%# DataBinder.Eval(Container.DataItem, "數(shù)據(jù)字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "數(shù)據(jù)字段2")%>’ />

  
7.表格點(diǎn)擊改變顏色

if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem)
{
 e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’;
    this.style.color=’buttontext’;this.style.cursor=’default’;");
}

  寫在DataGrid的_ItemDataBound里

if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem)
{
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’;
   this.style.color=’buttontext’;this.style.cursor=’default’;");
e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;");
}


  
8.關(guān)于日期格式

  日期格式設(shè)定

DataFormatString="{0:yyyy-MM-dd}"
  我覺得應(yīng)該在itembound事件中

e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd"))
 
 9.獲取錯(cuò)誤信息并到指定頁(yè)面

  不要使用Response.Redirect,而應(yīng)該使用Server.Transfer

  e.g

// in global.asax
protected void Application_Error(Object sender, EventArgs e) {
if (Server.GetLastError() is HttpUnhandledException)
Server.Transfer("MyErrorPage.aspx");

//其余的非HttpUnhandledException異常交給ASP.NET自己處理就okay了 :)
}

  Redirect會(huì)導(dǎo)致post-back的產(chǎn)生從而丟失了錯(cuò)誤信息,所以頁(yè)面導(dǎo)向應(yīng)該直接在服務(wù)器端執(zhí)行,這樣就可以在錯(cuò)誤處理頁(yè)面得到出錯(cuò)信息并進(jìn)行相應(yīng)的處理

  
10.清空Cookie

Cookie.Expires=[DateTime];
Response.Cookies("UserName").Expires = 0

  
11.自定義異常處理

//自定義異常處理類
using System;
using System.Diagnostics;

namespace MyAppException
{
 /// <summary>
 /// 從系統(tǒng)異常類ApplicationException繼承的應(yīng)用程序異常處理類。
 /// 自動(dòng)將異常內(nèi)容記錄到Windows NT/2000的應(yīng)用程序日志
 /// </summary>
 public class AppException:System.ApplicationException
 {
  public AppException()
  {
   if (ApplicationConfiguration.EventLogEnabled)LogEvent("出現(xiàn)一個(gè)未知錯(cuò)誤。");
  }

 public AppException(string message)
 {
  LogEvent(message);
 }

 public AppException(string message,Exception innerException)
 {
  LogEvent(message);
  if (innerException != null)
  {
   LogEvent(innerException.Message);
  }
 }

 //日志記錄類
 using System;
 using System.Configuration;
 using System.Diagnostics;
 using System.IO;
 using System.Text;
 using System.Threading;

 namespace MyEventLog
 {
  /// <summary>
  /// 事件日志記錄類,提供事件日志記錄支持
  /// <remarks>
  /// 定義了4個(gè)日志記錄方法 (error, warning, info, trace)

    WriteLog(TraceLevel.Error, message);
   }

   /// <summary>
   /// 將警告信息記錄到Win2000/NT事件日志中
   /// <param name="message">需要記錄的文本信息</param>
   /// </summary>
   public static void WriteWarning(String message)
   {
    WriteLog(TraceLevel.Warning, message);  
   }

   /// <summary>

   /// </retvalue>
   /// </summary>
   public static String FormatException(Exception ex, String catchInfo)
   {
    StringBuilder strBuilder = new StringBuilder();
    if (catchInfo != String.Empty)
    {
     strBuilder.Append(catchInfo).Append("\r\n");
    }
    strBuilder.Append(ex.Message).Append("\r\n").Append(ex.StackTrace);
    return strBuilder.ToString();
   }

   /// <summary>
   /// 實(shí)際事件日志寫入方法
   /// <param name="level">要記錄信息的級(jí)別(error,warning,info,trace).</param>
   /// <param name="messageText">要記錄的文本.</param>
   /// </summary>
   private static void WriteLog(TraceLevel level, String messageText)
   {
    try
    {
     EventLogEntryType LogEntryType;
     switch (level)
     {
      case TraceLevel.Error:
       LogEntryType = EventLogEntryType.Error;
       break;
      case TraceLevel.Warning:
       LogEntryType = EventLogEntryType.Warning;
       break;
      case TraceLevel.Info:
       LogEntryType = EventLogEntryType.Information;
       break;
      case TraceLevel.Verbose:
       LogEntryType = EventLogEntryType.SuccessAudit;
       break;
      default:
       LogEntryType = EventLogEntryType.SuccessAudit;
       break;
     }

     EventLog eventLog = new EventLog("Application", ApplicationConfiguration.EventLogMachineName, ApplicationConfiguration.EventLogSourceName );
     //寫入事件日志
     eventLog.WriteEntry(messageText, LogEntryType);

    }
   catch {} //忽略任何異常
  }
 } //class ApplicationLog
}
12.Panel 橫向滾動(dòng),縱向自動(dòng)擴(kuò)展

<asp:panel style="overflow-x:scroll;overflow-y:auto;"></asp:panel>
  13.回車轉(zhuǎn)換成Tab

<script language="javascript" for="document" event="onkeydown">
 if(event.keyCode==13 && event.srcElement.type!=’button’ && event.srcElement.type!=’submit’ &&     event.srcElement.type!=’reset’ && event.srcElement.type!=’’&& event.srcElement.type!=’textarea’);
   event.keyCode=9;
</script>

onkeydown="if(event.keyCode==13) event.keyCode=9"

  
14.DataGrid超級(jí)連接列

DataNavigateUrlField="字段名" DataNavigateUrlFormatString="http://xx/inc/delete.aspx?ID={0}"
  
15.DataGrid行隨鼠標(biāo)變色

private void DGzf_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
 if (e.Item.ItemType!=ListItemType.Header)
 {
  e.Item.Attributes.Add( "onmouseout","this.style.backgroundColor=\""+e.Item.Style["BACKGROUND-COLOR"]+"\"");
  e.Item.Attributes.Add( "onmouseover","this.style.backgroundColor=\""+ "#EFF3F7"+"\"");
 }
}

  
16.模板列

<ASP:TEMPLATECOLUMN visible="False" sortexpression="demo" headertext="ID">
<ITEMTEMPLATE>
<ASP:LABEL text=’<%# DataBinder.Eval(Container.DataItem, "ArticleID")%>’ runat="server" width="80%" id="lblColumn" />
</ITEMTEMPLATE>
</ASP:TEMPLATECOLUMN>

<ASP:TEMPLATECOLUMN headertext="選中">
<HEADERSTYLE wrap="False" horizontalalign="Center"></HEADERSTYLE>
<ITEMTEMPLATE>
<ASP:CHECKBOX id="chkExport" runat="server" />
</ITEMTEMPLATE>
<EDITITEMTEMPLATE>
<ASP:CHECKBOX id="chkExportON" runat="server" enabled="true" />
</EDITITEMTEMPLATE>
</ASP:TEMPLATECOLUMN>

  后臺(tái)代碼

protected void CheckAll_CheckedChanged(object sender, System.EventArgs e)
{
 //改變列的選定,實(shí)現(xiàn)全選或全不選。
 CheckBox chkExport ;
 if( CheckAll.Checked)
 {
  foreach(DataGridItem oDataGridItem in MyDataGrid.Items)
  {
   chkExport = (CheckBox)oDataGridItem.FindControl("chkExport");
   chkExport.Checked = true;
  }
 }
 else
 {
  foreach(DataGridItem oDataGridItem in MyDataGrid.Items)
  {
   chkExport = (CheckBox)oDataGridItem.FindControl("chkExport");
   chkExport.Checked = false;
  }
 }
}

  
17.數(shù)字格式化

  【<%#Container.DataItem("price")%>的結(jié)果是500.0000,怎樣格式化為500.00?】

<%#Container.DataItem("price","{0:¥#,##0.00}")%>

int i=123456;
string s=i.ToString("###,###.00");
18.日期格式化

  【aspx頁(yè)面內(nèi):<%# DataBinder.Eval(Container.DataItem,"Company_Ureg_Date")%>

  顯示為: 2004-8-11 19:44:28

  我只想要:2004-8-11 】


<%# DataBinder.Eval(Container.DataItem,"Company_Ureg_Date","{0:yyyy-M-d}")%>
  應(yīng)該如何改?

  【格式化日期】

  取出來(lái),一般是object((DateTime)objectFromDB).ToString("yyyy-MM-dd");

  【日期的驗(yàn)證表達(dá)式】

  A.以下正確的輸入格式: [2004-2-29], [2004-02-29 10:29:39 pm], [2004/12/31]

^((\d{2}(([02468][048])|([13579][26]))[\-\/\s]?((((0?[13578])|(1[02]))[\-\/\s]?((0?[1-9])|([1-2][0-9])|(3[01])))|(((0?[469])|(11))[\-\/\s]?((0?[1-9])|([1-2][0-9])|(30)))|(0?2[\-\/\s]?((0?[1-9])|([1-2][0-9])))))|(\d{2}(([02468][1235679])|([13579][01345789]))[\-\/\s]?((((0?[13578])|(1[02]))[\-\/\s]?((0?[1-9])|([1-2][0-9])|(3[01])))|(((0?[469])|(11))[\-\/\s]?((0?[1-9])|([1-2][0-9])|(30)))|(0?2[\-\/\s]?((0?[1-9])|(1[0-9])|(2[0-8]))))))(\s(((0?[1-9])|(1[0-2]))\:([0-5][0-9])((\s)|(\:([0-5][0-9])\s))([AM|PM|am|pm]{2,2})))?$
  B.以下正確的輸入格式:[0001-12-31], [9999 09 30], [2002/03/03]

^\d{4}[\-\/\s]?((((0[13578])|(1[02]))[\-\/\s]?(([0-2][0-9])|(3[01])))|(((0[469])|(11))[\-\/\s]?(([0-2][0-9])|(30)))|(02[\-\/\s]?[0-2][0-9]))$
  【大小寫轉(zhuǎn)換】

HttpUtility.HtmlEncode(string);
HttpUtility.HtmlDecode(string)

 


  
19.如何設(shè)定全局變量

  Global.asax中

  Application_Start()事件中

  添加Application[屬性名] = xxx;

  就是你的全局變量

  20.怎樣作到HyperLinkColumn生成的連接后,點(diǎn)擊連接,打開新窗口?

  HyperLinkColumn有個(gè)屬性Target,將器值設(shè)置成"_blank"即可.(Target="_blank")

  【ASPNETMENU】點(diǎn)擊菜單項(xiàng)彈出新窗口

  在你的menuData.xml文件的菜單項(xiàng)中加入U(xiǎn)RLTarget="_blank",如:

<?xml version="1.0" encoding="GB2312"?>
<MenuData ImagesBaseURL="images/">
<MenuGroup>
<MenuItem Label="內(nèi)參信息" URL="Infomation.aspx" >
<MenuGroup ID="BBC">
<MenuItem Label="公告信息" URL="Infomation.aspx" URLTarget="_blank" LeftIcon="file.gif"/>
<MenuItem Label="編制信息簡(jiǎn)報(bào)" URL="NewInfo.aspx" LeftIcon="file.gif" />
......

  最好將你的aspnetmenu升級(jí)到1.2版

  
21.讀取DataGrid控件TextBox值

foreach(DataGrid dgi in yourDataGrid.Items)
{
 TextBox tb = (TextBox)dgi.FindControl("yourTextBoxId");
 tb.Text....
}

  23.在DataGrid中有3個(gè)模板列包含Textbox分別為 DG_ShuLiang (數(shù)量) DG_DanJian(單價(jià)) DG_JinE(金額)分別在5.6.7列,要求在錄入數(shù)量及單價(jià)的時(shí)候自動(dòng)算出金額即:數(shù)量*單價(jià)=金額還要求錄入時(shí)限制為 數(shù)值型.我如何用客戶端腳本實(shí)現(xiàn)這個(gè)功能?

  〖思?xì)w〗

<asp:TemplateColumn HeaderText="數(shù)量">
<ItemTemplate>
<asp:TextBox id="ShuLiang" runat=’server’ Text=’<%# DataBinder.Eval(Container.DataItem,"DG_ShuLiang")%>’
onkeyup="javascript:DoCal()"
/>

<asp:RegularExpressionValidator id="revS" runat="server" ControlToValidate="ShuLiang" ErrorMessage="must be integer" ValidationExpression="^\d+$" />
</ItemTemplate>
</asp:TemplateColumn>

<asp:TemplateColumn HeaderText="單價(jià)">
<ItemTemplate>
<asp:TextBox id="DanJian" runat=’server’ Text=’<%# DataBinder.Eval(Container.DataItem,"DG_DanJian")%>’
onkeyup="javascript:DoCal()"
/>

<asp:RegularExpressionValidator id="revS2" runat="server" ControlToValidate="DanJian" ErrorMessage="must be numeric" ValidationExpression="^\d+(\.\d*)?$" />

</ItemTemplate>
</asp:TemplateColumn>

<asp:TemplateColumn HeaderText="金額">
<ItemTemplate>
<asp:TextBox id="JinE" runat=’server’ Text=’<%# DataBinder.Eval(Container.DataItem,"DG_JinE")%>’ />
</ItemTemplate>
</asp:TemplateColumn><script language="javascript">
function DoCal()
{
 var e = event.srcElement;
 var row = e.parentNode.parentNode;
 var txts = row.all.tags("INPUT");
 if (!txts.length || txts.length < 3)
  return;

 var q = txts[txts.length-3].value;
 var p = txts[txts.length-2].value;

 if (isNaN(q) || isNaN(p))
  return;

 q = parseInt(q);
 p = parseFloat(p);

 txts[txts.length-1].value = (q * p).toFixed(2);
}
</script>

24.datagrid選定比較底下的行時(shí),為什么總是刷新一下,然后就滾動(dòng)到了最上面,剛才選定的行因屏幕的關(guān)系就看不到了。

page_load
page.smartNavigation=true

  
25.在Datagrid中修改數(shù)據(jù),當(dāng)點(diǎn)擊編輯鍵時(shí),數(shù)據(jù)出現(xiàn)在文本框中,怎么控制文本框的大小 ?

private void DataGrid1_ItemDataBound(obj sender,DataGridItemEventArgs e)
{
 for(int i=0;i<e.Item.Cells.Count-1;i++)
  if(e.Item.ItemType==ListItemType.EditType)
  {
   e.Item.Cells[i].Attributes.Add("Width", "80px")
  }
}

  
26.對(duì)話框

private static string ScriptBegin = "<script language=\"JavaScript\">";
private static string ScriptEnd = "</script>";

public static void ConfirmMessageBox(string PageTarget,string Content)
{
 string ConfirmContent="var retValue=window.confirm(’"+Content+"’);"+"if(retValue){window.location=’"+PageTarget+"’;}";

 ConfirmContent=ScriptBegin + ConfirmContent + ScriptEnd;

 Page ParameterPage = (Page)System.Web.HttpContext.Current.Handler;
 ParameterPage.RegisterStartupScript("confirm",ConfirmContent);
 //Response.Write(strScript);
}

  27. 將時(shí)間格式化:string aa=DateTime.Now.ToString("yyyy年MM月dd日");

  1.1 取當(dāng)前年月日時(shí)分秒

currentTime=System.DateTime.Now;
  1.2 取當(dāng)前年

int 年= DateTime.Now.Year;
  1.3 取當(dāng)前月

int 月= DateTime.Now.Month;
  1.4 取當(dāng)前日

int 日= DateTime.Now.Day;
  1.5 取當(dāng)前時(shí)

int 時(shí)= DateTime.Now.Hour;
  1.6 取當(dāng)前分

int 分= DateTime.Now.Minute;
  1.7 取當(dāng)前秒

int 秒= DateTime.Now.Second;
  1.8 取當(dāng)前毫秒

int 毫秒= DateTime.Now.Millisecond;
  
28.自定義分頁(yè)代碼:

  先定義變量 :

public static int pageCount; //總頁(yè)面數(shù)
public static int curPageIndex=1; //當(dāng)前頁(yè)面

  下一頁(yè):

if(DataGrid1.CurrentPageIndex < (DataGrid1.PageCount - 1))
{
 DataGrid1.CurrentPageIndex += 1;
 curPageIndex+=1;
}

bind(); // DataGrid1數(shù)據(jù)綁定函數(shù)

  上一頁(yè):

if(DataGrid1.CurrentPageIndex >0)
{
 DataGrid1.CurrentPageIndex += 1;
 curPageIndex-=1;
}

bind(); // DataGrid1數(shù)據(jù)綁定函數(shù)

  直接頁(yè)面跳轉(zhuǎn):

int a=int.Parse(JumpPage.Value.Trim());//JumpPage.Value.Trim()為跳轉(zhuǎn)值

if(a<DataGrid1.PageCount)
{
 this.DataGrid1.CurrentPageIndex=a;
}

bind();
29.DataGrid使用:

  添加刪除確認(rèn):

private void DataGrid1_ItemCreated(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
 foreach(DataGridItem di in this.DataGrid1.Items)
 {
  if(di.ItemType==ListItemType.Item||di.ItemType==ListItemType.AlternatingItem)
  {
   ((LinkButton)di.Cells[8].Controls[0]).Attributes.Add("onclick","return confirm(’確認(rèn)刪除此項(xiàng)嗎?’);");
  }
 }
}

  樣式交替:

ListItemType itemType = e.Item.ItemType;

if (itemType == ListItemType.Item )
{
 e.Item.Attributes["onmouseout"] = "javascript:this.style.backgroundColor=’#FFFFFF’;";
 e.Item.Attributes["onmouseover"] = "javascript:this.style.backgroundColor=’#d9ece1’;cursor=’hand’;" ;
}
else if( itemType == ListItemType.AlternatingItem)
{
 e.Item.Attributes["onmouseout"] = "javascript:this.style.backgroundColor=’#a0d7c4’;";
 e.Item.Attributes["onmouseover"] = "javascript:this.style.backgroundColor=’#d9ece1’;cursor=’hand’;" ;
}

  添加一個(gè)編號(hào)列:

DataTable dt= c.ExecuteRtnTableForAccess(sqltxt); //執(zhí)行sql返回的DataTable
DataColumn dc=dt.Columns.Add("number",System.Type.GetType("System.String"));

for(int i=0;i<dt.Rows.Count;i++)
{
 dt.Rows[i]["number"]=(i+1).ToString();
}

DataGrid1.DataSource=dt;
DataGrid1.DataBind();

  DataGrid1中添加一個(gè)CheckBox,頁(yè)面中添加一個(gè)全選框

private void CheckBox2_CheckedChanged(object sender, System.EventArgs e)
{
 foreach(DataGridItem thisitem in DataGrid1.Items)
 {
  ((CheckBox)thisitem.Cells[0].Controls[1]).Checked=CheckBox2.Checked;
 }
}

  將當(dāng)前頁(yè)面中DataGrid1顯示的數(shù)據(jù)全部刪除

foreach(DataGridItem thisitem in DataGrid1.Items)
{
 if(((CheckBox)thisitem.Cells[0].Controls[1]).Checked)
 {
  string strloginid= DataGrid1.DataKeys[thisitem.ItemIndex].ToString();
  Del (strloginid); //刪除函數(shù)
 }
}

  30.當(dāng)文件在不同目錄下,需要獲取數(shù)據(jù)庫(kù)連接字符串(如果連接字符串放在Web.config,然后在Global.asax中初始化)

  在Application_Start中添加以下代碼:

Application["ConnStr"]=this.Context.Request.PhysicalApplicationPath+ConfigurationSettings.
   AppSettings["ConnStr"].ToString();

  31. 變量.ToString()

  字符型轉(zhuǎn)換 轉(zhuǎn)為字符串

12345.ToString("n"); //生成 12,345.00
12345.ToString("C"); //生成 ¥12,345.00
12345.ToString("e"); //生成 1.234500e+004
12345.ToString("f4"); //生成 12345.0000
12345.ToString("x"); //生成 3039 (16進(jìn)制)
12345.ToString("p"); //生成 1,234,500.00%

  32、變量.Substring(參數(shù)1,參數(shù)2);

  截取字串的一部分,參數(shù)1為左起始位數(shù),參數(shù)2為截取幾位。 如:string s1 = str.Substring(0,2);

  
33.在自己的網(wǎng)站上登陸其他網(wǎng)站:(如果你的頁(yè)面是通過(guò)嵌套方式的話,因?yàn)橐粋(gè)頁(yè)面只能有一個(gè)FORM,這時(shí)可以導(dǎo)向另外一個(gè)頁(yè)面再提交登陸信息)

<SCRIPT language="javascript">
<!--
 function gook(pws)
 {
  frm.submit();
 }
//-->

</SCRIPT> <body leftMargin="0" topMargin="0" onload="javascript:gook()" marginwidth="0" marginheight="0">
<form name="frm" action=" http://220.194.55.68:6080/login.php?retid=7259 " method="post">
<tr>
<td>
<input id="f_user" type="hidden" size="1" name="f_user" runat="server">
<input id="f_domain" type="hidden" size="1" name="f_domain" runat="server">
<input class="box" id="f_pass" type="hidden" size="1" name="pwshow" runat="server">

<INPUT id="lng" type="hidden" maxLength="20" size="1" value="5" name="lng">
<INPUT id="tem" type="hidden" size="1" value="2" name="tem">

</td>

</tr>

</form>

  文本框的名稱必須是你要登陸的網(wǎng)頁(yè)上的名稱,如果源碼不行可以用vsniffer 看看。

  下面是獲取用戶輸入的登陸信息的代碼:

string name;
name=Request.QueryString["EmailName"];
