我需要的Dispose（）或Close（）的的EventWaitHandle？ [英] Do I need to Dispose() or Close() an EventWaitHandle?

问题描述

如果我使用的EventWaitHandle （或的AutoResetEvent ，的ManualResetEvent ）在线程之间同步的话，我需要调用关闭（）或的Dispose（）在该方法事件句柄时，我用它我做了什么？

If I am using EventWaitHandle (or AutoResetEvent, ManualResetEvent) to synchronise between threads then do I need to call the Close() or Dispose() methods on that event handle when I am done with it?

的EventWaitHandle 从的WaitHandle 继承，它实现的IDisposable 。而FxCop的抱怨，如果我不落实的IDisposable 上包含一个的EventWaitHandle 任何类。因此，这意味着我需要调用它。

EventWaitHandle inherits from WaitHandle, which implements IDisposable. And FxCop complains if I don't implement IDisposable on any class that contains an EventWaitHandle. So this suggests that I do need to call it.

但是没有这些MSDN用法示例调用的Dispose（）或关闭（）：

However none of these MSDN usage examples call Dispose() or Close():

是微软忽略了自己的意见这只是举个例子？

Is this just an example of Microsoft ignoring their own advice?

推荐答案

您需要显式地处理它们。关闭（）更适合她们因为它调用Dispose（）。

You need to dispose them explicitly. Close() is more appropriate for them as it does call Dispose().
