c# - What happens when a .NET thread throws an exception?

Question

We have an interface IPoller for which we have various implementations. We have a process that will take an IPoller and start it in a separate thread. I'm trying to come up with a generic way of providing exception handling for any IPollers which don't do it themselves.

My original thinking was to create an implementation of IPoller that would accept an IPoller and just provide some logging functionality. The question I ran into though is how would I provide this error handling? If I have IPoller.Start() which is the target for the Thread is that where the exception will occur? Or is there something on the thread itself I can hook into?

Answer 1

Something like:

Thread thread = new Thread(delegate() {
    try
    {
        MyIPoller.Start();
    }
    catch(ThreadAbortException)
    {
    }
    catch(Exception ex)
    {
        //handle
    }
    finally
    {
    }
});

This will ensure the exception doesn't make it to the top of the thread.
