這是在VB.net中為連接MySql中編寫的一個類庫。你可以使用這個類庫直接操作MySql數(shù)據(jù)庫。

　　在使用這個類庫之前，你必須安裝
　　ODBC MYSQL 3.51下載地址：http://www.mysql.com/downloads/api-myodbc-3.51.html
　　Driver ODBC.NET下載地址：http://www.microsoft.com/downloads/details.aspx?FamilyId=6CCD8427-1017-4F33-A062-D165078E32B1&displaylang=en 

　　在這個庫中有三個類：
　　ManipStringForMySQL: 此類修改SGBD的字符串
　　MySQL_Requettes: 發(fā)送請求
　　MySQL_Utils : 對SGBD數(shù)據(jù)進行測試

　　下面是使用此類庫操作MySql的一個例子

　　//對DataSet進行操作

　 Public Shared Function MyODBCDataset(ByVal ReqSQL As String, _
         ByVal LaBase As String, ByVal Server As String, _
         ByVal Password As String, ByVal User As String, _
         ByVal NomDataSet As String) As DataSet
    ' Connexion à un server MySQL
    'avec le Driver ODBC 3.51 avec requette qui renvoie un dataset
    Dim MyConString As String = _
        "DRIVER={MySQL ODBC 3.51 Driver};SERVER=" & Server _
        & ";DATABASE=" & LaBase & ";UID=" & User _
        & ";PASSWORD=" & Password & ";OPTION=3;"
　 Dim MyODBCConnexion As New OdbcConnection(MyConString)
    Try
        Dim ds As New DataSet()
        Dim cmd As OdbcDataAdapter = New
        OdbcDataAdapter(ReqSQL, MyConString)
        Dim MyCommand As New OdbcCommand()
        Dim MyDataReader As OdbcDataReader
        cmd.Fill(ds, NomDataSet)
        MyODBCConnexion.Close()
        Return ds
    Catch MyOdbcException As OdbcException
    '
      HttpContext.Current.Response.Write(MyOdbcException.ToString)
    Catch MyException As Exception
    '
      HttpContext.Current.Response.Write(MyException.ToString)
    End Try
End Function

    //對函數(shù)的調(diào)用

  Dim MonDatasetTemp As DataSet = MySQL_Requettes.MyODBCDataset(
               SQL,
               constantes.ODBCBase,
               constantes.ODBCServer,
               constantes.ODBCPwd,
               constantes.ODBCUser,
               "MonDataset")
