C#实现函数超出指定时间，自动退出

代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading;

namespace HelloWorld
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Begin:" + DateTime.Now);
            bool ret = Process(string.Empty, 100);
            Console.WriteLine("Result={0}", ret);
            Console.WriteLine("End:" + DateTime.Now);
            Console.WriteLine("Press any key to exit...");
            Console.ReadKey(true);
        }
        private static bool Process(string param, int timeout)
        {
            bool ret = false;
            new System.Threading.Tasks.TaskFactory().StartNew(() => {
                ret = LongTimeFunc();
            }).Wait(timeout);
            Console.WriteLine("退出函数");
            return ret;
        }

        private static bool LongTimeFunc()
        {
            System.Threading.Thread.Sleep(50000000);
            return true;
        }
    }
}
