Sychronization of threads via events

[Dan]

The Win32 API lets you create named events via CreateEvent. However, the
..NET equivalents, AutoResetEvent and ManualResetEvent, don't appear to let
you do that. Is there a way to create the equivalent of a named event in
..NET?

Thanks...

Hi Dan:

There is no way to create a named event with the framework classes.
You'll have to PInvoke CreateEvent.

Dan,

In 1.1, you can call CreateEvent through the P/Invoke layer, and get the
handle to the event. Once you have it, you should be able to pass the
result to the Handle property of an AutoResetEvent or a ManualResetEvent
(whichever one is appropriate).

In .NET 2.0, you can use the EventWaitHandle class and pass a name
through the constructor. The inheritance chains for ManualResetEvent and
AutoResetEvent have been changed to derive from this (which in turn, derives
from WaitHandle).

Hope this helps.

I wrote a named event wrapper which you can get from here (the project also has a thread which expses a WaitHandle so you can wait on multiple threads too).
