在VB.net 中連接MySql的類庫

在使用這個類庫之前，你必須安裝

在這個庫中有三個類：

ManipStringForMySQL: 此類修改SGBD的字符串

MySQL_Requettes: 發送請求

MySQL_Utils : 對SGBD數據進行測試

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

    //對函數的調用

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