仅停止一个线程 [英] Stopping only one thread

问题描述

我的应用程序中有很多线程，如何仅停止其中的一个线程?如果我使用Thread.Sleep()，它将停止整个应用程序，我只想停止一个线程.我怎么做?我正在使用c#.

I have many threads in my application, how do I stop only one thread from them? If I use Thread.Sleep() it stops the whole application, I just want to stop a single thread. How do I do that? I am using c#.

推荐答案

使用Thread.Sleep()时，您仅停止调用此方法的线程.如果您的主线程(即UI线程)调用Thread.Sleep()，则应用程序冻结(实际上其他线程仍在继续工作，但未刷新UI).因此，如果您想停止某个线程，则:

When you are using Thread.Sleep() you are stopping only thread, which called this method. If your main thread (i.e. UI thread) calls Thread.Sleep(), then application freezes (actually other threads continue working, but UI is not refreshed). So, if you want to stop some thread, then:

• 它不应该是主线程
• 只需在该线程上调用Thread.Sleep()

示例(假设此代码在主线程上执行):

Example (assume this code is executed on main thread):

ThreadPool.QueueUserWorkItem(DoSomething);
Thread.Sleep(1000); // this will freeze application

这是一个回调(在后台线程上执行):

And this is a callback (which is executed on background thread):

static void DoSomething(object state)
{
    Thread.Sleep(5000); // this will not freeze application
}
