畢設(shè)是碰到這個(gè)問題，一直是手動(dòng)關(guān)閉Excel進(jìn)程-_-!今天碰巧看到，欣喜轉(zhuǎn)之：
－－－－－－－－－－－－－
關(guān)于在asp.net中調(diào)用Excel組件不能結(jié)束進(jìn)程的問題，常見的解決方法用的是下面這段代碼
wb.Close(null,null,null);app.Workbooks.Close();app.Quit();if(rng != null){
System.Runtime.InteropServices.Marshal.ReleaseComObject(rng);
rng = null;
}
if(ws != null){
System.Runtime.InteropServices.Marshal.ReleaseComObject(ws);
ws = null;
}
if(wb != null){ System.Runtime.InteropServices.Marshal.ReleaseComObject(wb);
wb = null;
}
if(app != null){ System.Runtime.InteropServices.Marshal.ReleaseComObject(app);
app = null;
}
GC.Collect();
雖然這段代碼在配置正確的情況下能自動(dòng)結(jié)束Excel進(jìn)程，但是前提是在操作Excel時(shí)沒有引發(fā)異常的情況下，如果有異常發(fā)生，那么Excel進(jìn)程將不能結(jié)束（比如：引用了一個(gè)在Excel文件中不存在的文本框時(shí)就會(huì)出現(xiàn)“HRESULT 中的異常：0x800A03EC。”），這時(shí)就要借助Process類的Kill()方法來結(jié)束，下面是我寫的測(cè)試代碼：
using System;using System.Diagnostics;using excel = Microsoft.Office.Interop.Excel;namespace ExcelTest{
/// <summary>
/// Excel的摘要說明。
/// </summary>
public class Excel
{
private DateTime beforeTime; //Excel啟動(dòng)之前時(shí)間
private DateTime afterTime; //Excel啟動(dòng)之后時(shí)間
excel.Application app;
excel.Workbook wb;
excel.Worksheet ws;
excel.Range rng;
excel.TextBox tb;
public Excel(string templetPath)
{
//實(shí)例化一個(gè)Excel Application對(duì)象并使其可見
beforeTime = DateTime.Now;
app = new excel.ApplicationClass();
app.Visible = true;
afterTime = DateTime.Now;
wb = app.Workbooks.Open(templetPath,Type.Missing,Type.Missing,Type.Missing,Type.Missing,Type.Missing,Type.Missing,Type.Missing,Type.Missing,Type.Missing,Type.Missing,Type.Missing,Type.Missing,Type.Missing,Type.Missing);
ws = (excel.Worksheet)wb.Worksheets.get_Item(1);
}
public void ExcelMethod()
{
rng = ws.get_Range("B5","C7");
rng.Merge(excel.XlAxisCrosses.xlAxisCrossesAutomatic);
rng.Value2 = "Excel2003";
rng = ws.get_Range("D8","E11");
rng.MergeCells = true;
rng.Value2 = "Excel2003";
rng.HorizontalAlignment = excel.XlHAlign.xlHAlignCenter;
rng.VerticalAlignment = excel.XlVAlign.xlVAlignCenter;
rng = ws.get_Range("A1",Type.Missing);
rng.Value2 = 5;
rng = ws.get_Range("A2",Type.Missing);
rng.Value2 = 7;
for(int i=1;i<100;i++)
{
string s = string.Concat("G",i.ToString());
rng = ws.get_Range(s,Type.Missing);
rng.Value2 = i.ToString();
}
tb = (excel.TextBox)ws.TextBoxes("文本框 1");
tb.Text = "作 者";
tb = (excel.TextBox)ws.TextBoxes("文本框 2");
tb.Text = "KLY.NET的Blog";
tb = (excel.TextBox)ws.TextBoxes("文本框 3");
tb.Text = "日 期";
try
{
tb = (excel.TextBox)ws.TextBoxes("文本框 5");
tb.Text = DateTime.Now.ToShortDateString();
}
catch
{
//這里用Dispose()方法結(jié)束不了Excel進(jìn)程，所有還是要用Process的Kill()方法配合使用
// this.Dispose();
this.KillExcelProcess();
throw new Exception("不存在ID為\"文本框 5\"的文本框！");
}
finally
{
//如果有異常發(fā)生，Dispose()方法放在這里也結(jié)束不了Excel進(jìn)程
// this.Dispose();
//如果發(fā)生異常，在這里也可以結(jié)束Excel進(jìn)程
// this.KillExcelProcess();
}
}
/// <summary>
/// 另存為Excel文件
/// </summary>
/// <param name="savePath">保存路徑</param>
public void SaveAsExcelFile(string savePath)
{
wb.SaveAs(savePath,excel.XlFileFormat.xlHtml,Type.Missing,Type.Missing,Type.Missing,Type.Missing,excel.XlSaveAsAccessMode.xlExclusive,Type.Missing,Type.Missing,Type.Missing,Type.Missing,Type.Missing);
}
/// <summary>
/// 結(jié)束Excel進(jìn)程
/// </summary>
public void KillExcelProcess()
{
Process[] myProcesses;
DateTime startTime;
myProcesses = Process.GetProcessesByName("Excel");
//得不到Excel進(jìn)程ID，暫時(shí)只能判斷進(jìn)程啟動(dòng)時(shí)間
foreach(Process myProcess in myProcesses)
{
startTime = myProcess.StartTime;
if(startTime > beforeTime && startTime < afterTime)
{
myProcess.Kill();
}
}
}
/// <summary>
/// 如果對(duì)Excel的操作沒有引發(fā)異常的話，用這個(gè)方法可以正常結(jié)束Excel進(jìn)程
/// 否則要用KillExcelProcess()方法來結(jié)束Excel進(jìn)程
/// </summary>
public void Dispose()
{
wb.Close(null,null,null);
app.Workbooks.Close();
app.Quit();
//注意：這里用到的所有Excel對(duì)象都要執(zhí)行這個(gè)操作，否則結(jié)束不了Excel進(jìn)程
if(rng != null)
{
System.Runtime.InteropServices.Marshal.ReleaseComObject(rng);
rng = null;
}
if(tb != null)
{
System.Runtime.InteropServices.Marshal.ReleaseComObject(tb);
tb = null;
}
if(ws != null)
{
System.Runtime.InteropServices.Marshal.ReleaseComObject(ws);
ws = null;
}
if(wb != null)
{
System.Runtime.InteropServices.Marshal.ReleaseComObject(wb);
wb = null;
}
if(app != null)
{
System.Runtime.InteropServices.Marshal.ReleaseComObject(app);
app = null;
}
GC.Collect();
}
}
}
這段代碼能很好的解決Excel進(jìn)程不能正常結(jié)束的問題，如果主機(jī)操作系統(tǒng)不是服務(wù)器版的話，那么就要借助于ntsd -c q -p pid命令來結(jié)束。
還有一個(gè)問題的關(guān)于Excel組件訪問權(quán)限的配置，一定要在組件服務(wù)里面正確配置，否則結(jié)束不了Excel進(jìn)程，具體的配置方法在我項(xiàng)目的doc文件夾下；在我前面的文章里面介紹了在web.config文件里面加入假扮用戶的方法，但是經(jīng)我測(cè)試發(fā)現(xiàn)這種方法雖然可以訪問Excel組件，但是結(jié)束不了進(jìn)程，除非用Kill方法強(qiáng)行結(jié)束。
