.NET Mutext.ReleaseMutex和Mutex.Close [英] .NET Mutext.ReleaseMutex and Mutex.Close

问题描述

什么是两者之间的区别是什么？如果我关闭我的应用程序时做Mutext.Close（）这一翻译Mutext.Release（）的，会是什么副作用？

What's the difference between the two? If I do Mutext.Close() intead of Mutext.Release() when shutting down my app, what would be the side effect?

<一个href="http://msdn.microsoft.com/en-us/library/system.threading.mutex.releasemutex%28v=VS.90%29.aspx">ReleaseMutex是用来让另一个线程来获取互斥锁。如果你已经获得互斥（名为的WaitOne 和获得，或通过构造收购）时，才应调用。 重要说明 ReleaseMutex 如果您还没有获取互斥会抛出异常。

ReleaseMutex is used to allow another thread to obtain the mutex. It should only be called if you have acquired the mutex (called WaitOne and acquired it or acquired through the constructor). Important Note ReleaseMutex will throw an exception if you have not acquired the mutex.

Close is used to clean up the resources that have been allocated by declaring the mutex object, whether you ever blocked on it or not, if you have acquired the mutex it will release it (equivalent to calling ReleaseMutex. If you plan to lock on the mutex for the whole application (i.e. using this to ensure a single instance of your app), then I would wrap it in a using statement like the example in Joseph Albahari's threading guide (a must read).
