Sleep的问题

先上全部源码：

 using System;
 using System.Threading;

 namespace MoveServices
 {
     public static class MoveWorker
     {
         private static Random random = new Random();
         public static void DoWork()
         {
             while (true)
             {
                 , );
                 Console.WriteLine("{0}\ttime={1}", DateTime.Now.ToString("HH:mm:ss.fff"), time);
                 Thread.Sleep(time > - ? time *  : time);
             }
         }
     }
 }

 using System;
 using System.Threading;

 namespace MoveServices
 {
     class Program
     {
         static void Main(string[] args)
         {
             while (true)
             {
                 try
                 {
                     MoveWorker.DoWork();
                 }
                 catch (Exception exception)
                 {
                     Console.WriteLine("{0}\texception：{1}", DateTime.Now.ToString("HH:mm:ss.fff"), exception.Message);
                 }
                 finally
                 {
                     Thread.Sleep();
                 }
             }
         }
     }
 }

当随机数time=-1的时候，程序会无限暂停，因为Thread.Sleep(-1)相当于sleep(UINT_MAX)。不说了，只有吃过亏才会深刻理解。
