我和我的信息学课程中的'团队'一直试图让程序运行并将其连接到SQL服务器,似乎我们不断收到错误。你能不能帮我解决问题,我一直试图解决这个问题,所以欢迎任何帮助。

我们到目前为止的代码:

    Try
        Dim conn As New MySqlConnection
        Dim test As String = 64012478
        conn.ConnectionString = "User ID=*****_****; Password=******; Initial Catalog=dainformat_idea; Data Source=(IP of website);"
        conn.Open()
        Dim query = "SELECT * From students"
        Dim commando As New MySqlCommand(query, conn)
        Dim reader As MySqlDataReader = commando.ExecuteReader
        reader.Read()
        If reader.HasRows Then
            MessageBox.Show(reader(0) & " " & reader(1) & "Kaas")
            Exit Sub
        Else
            MessageBox.Show("Could not find something")
            Exit Sub
        End If
        conn.Close()
    Catch ex As Exception
        MessageBox.Show(ex.Message)
    End Try`

您正在尝试将SQL Server与MySQL库连接...如果您在服务器上安装了mySQL,代码将运行正常,但只有您拥有mysql,否则连接将失败。
