C#实现带有超时功能的回调函数类

http://www.blue1000.com/bkhtml/c17/2013-01/71047.htm

有时候我们需要控制方法的执行时间,如果超时则强制退出。

要控制执行时间,我们必须使用异步模式,在另外一个线程中执行方法,如果超时,则抛出异常终止线程执行。

如下实现的方法:

class Program
{

    static void Main(string[] args)
    {
        //try the five second method with a 6 second timeout
        CallWithTimeout(FiveSecondMethod, 6000);

        //try the five second method with a 4 second timeout
        //this will throw a timeout exception
        CallWithTimeout(FiveSecondMethod, 4000);
    }

    static void FiveSecondMethod()
    {
        Thread.Sleep(5000);
    }
    static void CallWithTimeout(Action action, int timeoutMilliseconds)
    {
        Thread threadToKill = null;
        Action wrappedAction = () =>
        {
            threadToKill = Thread.CurrentThread;
            action();
        };

        IAsyncResult result = wrappedAction.BeginInvoke(null, null);
        if (result.AsyncWaitHandle.WaitOne(timeoutMilliseconds))
        {
            wrappedAction.EndInvoke(result);
        }
        else
        {
            threadToKill.Abort();
            throw new TimeoutException();
        }
    }

}
