任务超时退出的方法 C#

超出时间方法退出。防止卡住。

方法：


private static bool ImportTaskTimeout(Action method, int hours)
        {
            try
            {
                var task = Task.Run(() => method());
                if (task.Wait(TimeSpan.FromHours(hours)))
                    return task.IsCompleted;
                else
                    return false;
            }
            catch
            {
                return false;
            }
        }

 

或者：

 static void Main(string[] args)
        {
            Task t = Task.Run(() => {
                Random rnd = new Random();
                long sum = 0;
                int n = 5000000;
                for (int ctr = 1; ctr <= n; ctr++)
                {
                    int number = rnd.Next(0, 101);
                    sum += number;
                    Console.WriteLine("ctr:    {0:N0}", ctr);
                }
            });
            TimeSpan ts = TimeSpan.FromMilliseconds(150);
            if (!t.Wait(ts))
                Console.WriteLine("The timeout interval elapsed.");
        }
