我认为,你可以与一位时间和代表一道这样做,我的榜样守则如下:

using System;
using System.Timers;

class Program
{
    public delegate void tm();

    static void Main(string[] args)
    {
        var t = new tm(tryMethod);
        var timer = new Timer();
        timer.Interval = 5000;

        timer.Start();

        timer.Elapsed += (sender, e) => timer_Elapsed(t);
        t.BeginInvoke(null, null);
    }

    static void timer_Elapsed(tm p)
    {
        p.EndInvoke(null);
        throw new TimeoutException();
    }

    static void tryMethod()
    {
        Console.WriteLine("FooBar");
    }
}

您尝试了Method,然后你创建了一名代表,并在Method上指出这位代表,然后,你开始担任这一代表。 然后,你有时间,间隔时间为5000米,你将你的代表转往你的时间过长的方法(代表应是一个参考类型,而不是一个价值类别),一旦5 000秒已经过去,你就把Envoke方法称作代表。

只要试图解决问题,就应该做你想要做的事情:

• 移动时节省日光时间或改变时区的安全:

DateTime startTime = DateTime.Now;

while(true)
{
    tryMethod();
    if(DateTime.Now.Subtract(startTime).TotalMilliseconds > 5000)
        throw new TimeoutException();
}

时区和日光节省时间

DateTime startTime = DateTime.UtcNow;

while(true)
{
    tryMethod();
    if(DateTime.UtcNow.Subtract(startTime).TotalMilliseconds > 5000)
        throw new TimeoutException();
} 

(www.net 3.5或更高, 日期:Offset)

DateTimeOffset startTime = DateTimeOffset.Now;

while(true)
{
    tryMethod();
    if(DateTimeOffset.Now.Subtract(startTime).TotalMilliseconds > 5000)
        throw new TimeoutException();
} 

Using Tasks f或 custom timeout on Async method

在此,我采用一种方法,总结出时间的任务。

public class TaskWithTimeoutWrapper
{
    protected volatile bool taskFinished = false;

    public async Task<T> RunWithCustomTimeoutAsync<T>(int millisecondsToTimeout, Func<Task<T>> taskFunc, CancellationTokenSource cancellationTokenSource = null)
    {
        this.taskFinished = false;

        var results = await Task.WhenAll<T>(new List<Task<T>>
        {
            this.RunTaskFuncWrappedAsync<T>(taskFunc),
            this.DelayToTimeoutAsync<T>(millisecondsToTimeout, cancellationTokenSource)
        });

        return results[0];
    }

    public async Task RunWithCustomTimeoutAsync(int millisecondsToTimeout, Func<Task> taskFunc, CancellationTokenSource cancellationTokenSource = null)
    {
        this.taskFinished = false;

        await Task.WhenAll(new List<Task>
        {
            this.RunTaskFuncWrappedAsync(taskFunc),
            this.DelayToTimeoutAsync(millisecondsToTimeout, cancellationTokenSource)
        });
    }

    protected async Task DelayToTimeoutAsync(int millisecondsToTimeout, CancellationTokenSource cancellationTokenSource)
    {
        await Task.Delay(millisecondsToTimeout);

        this.ActionOnTimeout(cancellationTokenSource);
    }

    protected async Task<T> DelayToTimeoutAsync<T>(int millisecondsToTimeout, CancellationTokenSource cancellationTokenSource)
    {
        await this.DelayToTimeoutAsync(millisecondsToTimeout, cancellationTokenSource);

        return default(T);
    }

    protected virtual void ActionOnTimeout(CancellationTokenSource cancellationTokenSource)
    {
        if (!this.taskFinished)
        {
            cancellationTokenSource?.Cancel();
            throw new NoInternetException();
        }
    }

    protected async Task RunTaskFuncWrappedAsync(Func<Task> taskFunc)
    {
        await taskFunc.Invoke();

        this.taskFinished = true;
    }

    protected async Task<T> RunTaskFuncWrappedAsync<T>(Func<Task<T>> taskFunc)
    {
        var result = await taskFunc.Invoke();

        this.taskFinished = true;

        return result;
    }
}

然后,你可以这样说:

await new TaskWithTimeoutWrapper().RunWithCustomTimeoutAsync(10000, () => this.MyTask());

或

var myResult = await new TaskWithTimeoutWrapper().RunWithCustomTimeoutAsync(10000, () => this.MyTaskThatReturnsMyResult());

如果你想要取消当成不变的任务,那么你可以增加取消。

另一种方式是:

public class TimeoutAction
    {
        private Thread ActionThread { get; set; }
        private Thread TimeoutThread { get; set; }
        private AutoResetEvent ThreadSynchronizer { get; set; }
        private bool _success;
        private bool _timout;

        /// <summary>
        /// 
        /// </summary>
        /// <param name="waitLimit">in ms</param>
        /// <param name="action">delegate action</param>
        public TimeoutAction(int waitLimit, Action action)
        {
            ThreadSynchronizer = new AutoResetEvent(false);
            ActionThread = new Thread(new ThreadStart(delegate
            {
                action.Invoke();
                if (_timout) return;
                _timout = true;
                _success = true;
                ThreadSynchronizer.Set();
            }));

            TimeoutThread = new Thread(new ThreadStart(delegate
            {
                Thread.Sleep(waitLimit);
                if (_success) return;
                _timout = true;
                _success = false;
                ThreadSynchronizer.Set();
            }));
        }

        /// <summary>
        /// If the action takes longer than the wait limit, this will throw a TimeoutException
        /// </summary>
        public void Start()
        {
            ActionThread.Start();
            TimeoutThread.Start();

            ThreadSynchronizer.WaitOne();

            if (!_success)
            {
                throw new TimeoutException();
            }
            ThreadSynchronizer.Close();
        }
    }

CancellationTokenSource cts = new CancellationTokenSource();
cts.CancelAfter(10000);
try
{
    Task task = Task.Run(() => { methodToTimeoutAfter10Seconds(); }, cts.Token);
    TaskCompletionSource<bool> tcs = new TaskCompletionSource<bool>();
    using (cts.Token.Register(s => ((TaskCompletionSource<bool>)s).TrySetResult(true), tcs))
    {
        if (task != await Task.WhenAny(task, tcs.Task))
        {
            throw new OperationCanceledException(cts.Token);
        }
    }
    /* Wait until the task is finish or timeout. */
    task.Wait();

    /* Rest of the code goes here */
    
}
catch (TaskCanceledException)
{
    Console.WriteLine("Timeout");
}
catch (OperationCanceledException)
{
    Console.WriteLine("Timeout");
}
catch (Exception ex)
{
    Console.WriteLine("Other exceptions");
}
finally
{
    cts.Dispose();
}
