901227-C#中需要WaitForSingleObject [英] 901227 - WaitForSingleObject is needed in C#

问题描述

嗨 在函数中，必须等待直到引发特殊变量重置或特殊事件.我要如何等待该功能?
在C ++中，这可以由WaitForSingleObject完成. RegisterWaitForSingleObject可能无济于事，因为它注册了单独的功能.我需要在相同的函数中等待，并且直到事件发生时才返回.
我该怎么办?
thx

解决方案

从System.Threading.WaitHandle派生的许多类中都可以使用此方法，请参见:
http://msdn.microsoft.com/en-us/library/system.threading. waithandle.aspx [ ^ ].

Paulo指出的两个当然很重要，但是除了使用它们之外，还可以使用其父类在功能上涵盖这两种情况(手动或自动重置).此类为System.Threading.EventWaitHandle:
http://msdn.microsoft.com/en-us/library/system.threading. eventwaithandle.aspx [ ^ ].

请参见类AutoResetEvent和ManualResetEvent.
WaitForSingleObject实际上是WaitOne方法.

hi in a function a wait must be done until a special variable reset or a special event is raised. how can i wait in the function?
in C++, this would be possible to be done by WaitForSingleObject. RegisterWaitForSingleObject may not help, because it registers a separate function. i need to wait in the same function and don''t return until the event occurs.
what can i do?
thx

解决方案

This method is available in a number of classes derived from System.Threading.WaitHandle, please see:
http://msdn.microsoft.com/en-us/library/system.threading.waithandle.aspx[^].

The two pointed out by Paulo are of course very important, but instead of using them, one could use its parent class functionally covering both cases (manual or auto reset); this class is System.Threading.EventWaitHandle:
http://msdn.microsoft.com/en-us/library/system.threading.eventwaithandle.aspx[^].

See the classes AutoResetEvent and ManualResetEvent.
The WaitForSingleObject is effectively the WaitOne method.

You can also look for "slim" version of those classes in my article: Managed Thread Synchronization[^]
