[.net 多线程]ThreadPool

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

两种出发模式：定时8s出发，事件触发器出发（autoresetevent）

AutoResetEvent evt = new AutoResetEvent(false);
ThreadPool.RegisterWaitForSingleObject(evt, (state, isOut) =>
{
    CancellationTokenSource token = (CancellationTokenSource)state;
    if (tocken.IsCancellationRequested)
    {
        Console.WriteLine("退出RWFS");
        return;
    }
    Console.WriteLine("RWFS...");
}, tocken, 8000, false);
