Check AutoResetEvent state

Question

Is it possible to check how actually AutoResetEvent object was treated? Is it fired by timeout or by calling Set() from another method?

Here is my code.

private AutoResetEvent autoResetEvent = new AutoResetEvent(false);
private int timeout = 30000;

public void SyncMethod()
{
    // some code before
    autoResetEvent.WaitOne(timeout);
    // if autoResetEvent called by timeout then { do some stuff } 
    // some code after
}
public void AsyncMethod()
{
    // some code before
    // ok I am done
    autoResetEvent.Set();
}

WaitHandle::WaitOne Method (Int32)

Return Value Type: System::Boolean

true if the current instance receives a signal; otherwise, false.

So, false is returned after timeout.

Yes, check the return value

true if the current instance receives a signal; otherwise, false.
