I create a register page for my web application. The application require that after user successfully register a new account, the page will show a message "Register successfully", then wait for 5 seconds before switch to Login page. I used Thread.Sleep(5000). It wait for 5 seconds but it does not display the message. Can anyone help me?

void AccountServiceRegisterCompleted(object sender, RegisterCompletedEventArgs e)
    {
        if (e.Result)
        {
            lblMessage.Text = "Register successfully";

            Thread.Sleep(5000); 
            this.SwitchPage(new Login());
        }
        else
        {
            ...
        }
    }

推荐答案

Thread.Sleep(5000)仅将您的线程挂起5秒钟-在这段时间内将不执行任何代码到该线程上.因此没有消息或其他任何内容.

Thread.Sleep(5000) only suspends your thread for 5 seconds - no code onto this thread will be executed during this time. So no messages or anything else.

如果它是ASP.NET应用程序，则客户端不知道服务器上正在发生什么，并等待服务器的响应5秒钟.您必须手动实现此逻辑.例如，使用JavaScript:

If it's an ASP.NET app, client doesn't know what's going on on server and waits server's response for 5 seconds. You have to implement this logic manually. For example, either using JavaScript:

setTimeout(function(){location.href = 'test.aspx';}, 5000);

或添加HTTP标头:

Response.AddHeader("REFRESH","5;URL=test.aspx");

或meta标签:

<meta http-equiv="refresh" content="5; url=test.aspx" />

请参见更多信息.

如果它是桌面应用程序，则可以使用计时器.并且永远不要使主线程(UI线程)挂在诸如Thread.Sleep之类的地方.

If it's a desktop application you could use something like timers. And never make main thread (UI Thread) hangs with something like Thread.Sleep.
