推荐答案

你正在暂停winform的主线程用那个代码。这意味着您的应用程序基本上所有处理都会停止。

请注意，您提到了计时器，但是您正在暂停_thread_。因为你提到了webbrowser控件，我假设你在那里展示了一些你可以控制的内容。

在这种情况下你会想要使用JavaScript（是的！）并使用setTimeout（）或者的setInterval（）。查看： JavaScript时间事件 [ ^ ]

You are pausing the main thread of your winform with that code. That means that basically all processing stops for your app.
Notice that you mentioned timer, but you are pausing the _thread_. Because you mentioned the webbrowser control I'm assuming you are showing some content in there that you have control over.
In that case you will want to use JavaScript (yeah!) and use setTimeout() or setInterval(). Check out : JavaScript Timing Events[^]
