在VB.NET中增加SqlCommand.CommandTimeout

Question

我想在VB.NET中增加SqlCommand.CommandTimeout， 我想把它提高到三分钟。

我试试这个：

Public Function SQL_send(ByVal Command As String) As String
    Dim myConnection As SqlConnection
    Dim myCommand As SqlCommand
    Dim dr As SqlDataReader
    Dim databases As New ArrayList
    'declaring the objects




    myConnection = New SqlConnection("server=" & sql_server & ";uid=" & sql_user & ";pwd=" & sql_pasword & ";database=" & sql_database)

    'establishing connection. you need to provide password for sql server

    myConnection.Open()
    'opening the connection
    myCommand = New SqlCommand(Command, myConnection)
    myCommand.CommandTimeout = 300

    'executing the command and assigning it to connection 
    myCommand.ExecuteScalar()

    myConnection.Close()

    Console.WriteLine(Command & vbCrLf)
End Function

但是它没有用，它停留了30秒。

有人有想法吗？谢谢！
