Thread A calls a delegate on Thread B but Thread A executes it!?!?

OK, I have a multi-threaded application.
I have a master thread which calls a delegate which I want the child thread
to execute but that is not happening, instead the master thread is running
the code in the delegate function. I know this as I can see the thread
id's.

This is what I *want* to happen

i.e.
(Master Thread:)
this.Invoke( DelegateA )

.....

(Child Thread)
private void DelegateFunction()
{
....
}


Is there anyway I can get this to happen?

Thread B needs to be waiting to receive the work in some form or other.
I have an example of something like this with the producer/consumer
queue in my threading article:

Try doing a DelegateA.BeginInvoke instead of an Invoke. And realize that you
will either need to create a callback method that handle the completion of
the process by calling an EndInvoke, just to clean things up.

That won't call it on a particular thread though - it'll call it on a
threadpool thread. That may be okay, but it may not be.
 
Just currious but, why do you want to execute a method on a specific thread?
