Note that I did find one way to do it, but this looks more like material for The Daily WTF:

catch (Exception ex)
{
    switch (ex.GetType().Name)
    {
        case "System.FormatException":
        case "System.OverflowException":
            WebId = Guid.Empty;
            break;
        default:
            throw;
    }
}
