C#中执行动作超时检测

public delegate void DoHandler();
    public class TimeoutLimit
    {
        private readonly ManualResetEvent _mTimeoutObject;
        private bool _timeout;
        public DoHandler Do;

        public TimeoutLimit()
        {
            _mTimeoutObject = new ManualResetEvent(true);
        }
        public bool DoWithTimeout(TimeSpan timeSpan)
        {
            if (Do == null)
            {
                return false;
            }
            _mTimeoutObject.Reset();
            _timeout = true;
            Do.BeginInvoke(DoAsyncCallBack, null);
            if (!_mTimeoutObject.WaitOne(timeSpan, false))
            {
                _timeout = true;
            }
            return _timeout;
        }
        private void DoAsyncCallBack(IAsyncResult result)
        {
            try
            {
                Do.EndInvoke(result);
                _timeout = false;
            }
            catch (Exception ex)
            {
                _timeout = true;
            }
            finally
            {
                _mTimeoutObject.Set();
            }
        }
    }

使用示例

//TimeoutLimit timeout = new TimeoutLimit { Do = Your Func };
//bool bo = timeout.TimeoutLimit(new TimeSpan(0, 0, 0, 1));
//if (bo) {Your Code}
