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")
