推荐答案

MessageBox用于Windows(与Web相对)应用程序.它将尝试在服务器上打开一个消息框.不允许这样做，这样会导致应用程序错误.

要在客户端上显示一条消息，您需要使用JavaScript-例如alert("message").

MessageBox is for use within windows (as opposed to web) applications. It would attempt to open a message box on the server. This is not allowed so that application errors.

To show a message on the client you would need to use JavaScript - such as alert("message").
