Does it make sense to catch ThreadAbortException and perform no action?

Question

catch (ThreadAbortException)
{ }
catch (Exception ex)
{
    TraceManager.TraceException(ex,
                                (int)ErrorCode.GENERIC_EXCEPTION,
                    


        

Answer 1

The ThreadAbortException can't be caught like that. It will get rethrown automatically at the end of the catch block unless you call Thread.ResetAbort();

Having a catch block as you have here for ThreadAbortException allows it to be auto-rethrown without the catch(Exception) block attempting to handle it.
