如何在C＃中实现类似JavaScript的setTimeout？

[英]how do I implement something like JavaScript's setTimeout in C#?

原文 2010-11-11 19:27:12 6 2 c#/ settimeout

I have a C# app that receives updates from a server, processes it, and updates the GUI. 我有一个C＃应用程序，它从服务器接收更新，处理它并更新GUI。 the updates come in constantly, say several times a second. 不断更新，每秒说几次。 I want the app to update the GUI at most once every 2 seconds. 我希望应用最多每2秒更新一次GUI。 so if an update comes in at time T, I want all updates that come in from T through T+2sec to stay in a buffer, and at T+2sec do the processing and GUI update. 因此，如果更新在时间T出现，我希望从T到T + 2sec的所有更新都保留在缓冲区中，并在T + 2sec进行处理和GUI更新。 I know in JS you can use setTimeout() to execute some code at some time in the future, so I want something like that. 我知道在JS中，您可以在将来的某个时候使用setTimeout（）执行一些代码，因此我需要类似的东西。

what's an appropriate way to do this? 有什么合适的方法做到这一点？ I've heard that using threads to "schedule" a function call isn't a great idea, but I'm not sure of a better way to do this. 我听说使用线程“调度”函数调用不是一个好主意，但是我不确定这样做的更好方法。 would it be so bad to use a Timer with a two second interval, synchronized to the GUI thread, that does the processing/updating? 使用间隔为两秒的计时器（与GUI线程同步）会很糟糕吗，该计时器会进行处理/更新吗？

2 个解决方案

You can use a System.Windows.Forms.Timer . 您可以使用System.Windows.Forms.Timer 。 It doesn't run events in a separate thread, it's the GUI thread that runs them. 它不会在单独的线程中运行事件，而是由GUI线程运行事件。 That way you can update the GUI directly without having to use Invoke. 这样，您可以直接更新GUI，而不必使用Invoke。

You should use one of the timer classes, as you posted in your question. 您应该使用在您的问题中发布的计时器类之一。

See this MSDN article comparing them - this should give you a good basis to make a decision. 请参阅此 MSDN文章对它们进行比较-这应该为您做出决定提供良好的基础。
