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//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")此程序用到的类库可在如下地址下载：http://www.codeproject.com/dotnet/MySQLConnexion/MySQLConnexion.zip
