Question

Is there any attribute that I can use, attached to the method definition, that will suppress any exceptions of a certain type originating in that method? e.g.

[SuppressException(typeof(TimeoutException))]
public void TroubleMethod()
{

}

So when there is a TimeoutException, it won’t throw outside of TroubleMethod?

Answer 1

You can use exception handling around the entire method:

public void TroubleMethod()
{
    try {
        // ...
    } catch(TimeoutException) {
        // Throw away
    }
}

I don’t think an attribute that does what you describe exists, though. If you want the debugger to step through your method, you can always use [System.Diagnostics.DebuggerStepThrough()], but as for suppressing exceptions, I don’t think that’s possible.
