.net 3.5 suspend

[jerry_zhang99]

在.net 3.5中，Thread.suspend() 和 Thread.Resume()被弃用了，请问一下都用什么来挂起和释放线程呢

Please use other classes in System.Threading, such as Monitor, Mutex, Event, and Semaphore, to synchronize Threads or protect resources. (请使用System.Threading中的其他类，如Monitor, Mutex, Event, 和Semaphore，以同步线程和保护资源。)



Thread.Suspend和Thread.Resume被废弃的主要原因是因为其使用很容易造成线程死锁(Deadlock)。

我是不知道用那个更合适，所以，问了下，最后我用的是 ManualResetEvent,还是不错，挺好用的。谢谢
