C#で動作タイムアウト検出を実行

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();

            }

        }

    }

使用例

//TimeoutLimit timeout = new TimeoutLimit { Do = Your Func };

//bool bo = timeout.TimeoutLimit(new TimeSpan(0, 0, 0, 1));

//if (bo) {Your Code}
