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(); } } }
