[.net 多线程]ThreadPool

1 CancellationTokenSource tocken = new CancellationTokenSource();
2 ThreadPool.QueueUserWorkItem(param => {
3     Console.WriteLine($"当前线程【{Thread.CurrentThread.ManagedThreadId}】");
4     Thread.Sleep(1000);
5     Console.WriteLine($"当前线程【{Thread.CurrentThread.ManagedThreadId}】退出");
6 }, tocken);

两种出发模式：定时8s出发，事件触发器出发（autoresetevent）

 1 AutoResetEvent evt = new AutoResetEvent(false);
 2 ThreadPool.RegisterWaitForSingleObject(evt, (state, isOut) =>
 3 {
 4     CancellationTokenSource token = (CancellationTokenSource)state;
 5     if (tocken.IsCancellationRequested)
 6     {
 7         Console.WriteLine("退出RWFS");
 8         return;
 9     }
10     Console.WriteLine("RWFS...");
11 }, tocken, 8000, false);
