Is there a good method in C# for throwing an exception on a given thread

Question

The code that I want to write is like this:

void MethodOnThreadA()
{
    for (;;)
    {
        // Do stuff
        if (ErrorConditionMet)
            ThrowO         


        

Answer 1

Like the others, I'm not sure that's such a good idea, but if you really want to do it, then you can create a subclass of SynchronizationContext that allows posting and sending delegates to the target thread (if it's a WinForms thread the work is done for you as such a subclass already exists). The target thread will have to implement some sort of a message pump equivalent though, to receive the delegates.

I take your point about an exception being thrown in the finally block.

However, I think there is a way - using yet another thread - of using this exception-as-interrupt idea.

Thread A:

At some random time, throw an exception on thread C:

Thread B:

try {
    Signal thread C that exceptions may be thrown
    //do stuff, without needing to check exit conditions
    Signal thread C that exceptions may no longer be thrown
}
catch {
    // exception/interrupt occurred handle...
}
finally {
    // ...and clean up
    CloseResourceOne();
    CloseResourceTwo();
}

Thread C:

 while(thread-B-wants-exceptions) {
        try {
            Thread.Sleep(1) 
        }
        catch {
            // exception was thrown...
            if Thread B still wants to handle exceptions
                throw-in-B
        }
    }

Or is that just silly?
