            .Net中操作MySql数据库的方法2007-04-27 ruoo korn这是在VB.net中为连接MySQL中编写的一个类库。你可以使用这个类库直接操作MySql数据库。 在使用这个类库之前,你必须安装 
  ODBC MYSQL 3.51下载地址:http://www.mysql.com/downloads/api-myodbc-3.51.html 
  Driver ODBC.NET下载地址:http://www.microsoft.com/downloads/details.aspx?FamilyId=6CCD8427-1017-4F33-A062-D165078E32B1&displaylang=en 在这个库中有三个类: 
  ManipStringForMySQL: 此类修改SGBD的字符串 
  MySQL_Requettes: 发送请求 
  MySQL_Utils : 对SGBD数据进行测试下面是使用此类库操作MySql的一个例子以下为引用的内容:
  //对DataSet进行操作 
  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 //对函数的调用 Dim MonDatasetTemp As DataSet = MySQL_Requettes.MyODBCDataset(
               SQL,
               constantes.ODBCBase, 
               constantes.ODBCServer, 
               constantes.ODBCPwd, 
               constantes.ODBCUser, 
               "MonDataset")
