Question

I have a catch block like below:

catch (Exception e)
            {
                connection.Close();
                return null;
            }

I get a warning saying ‘e’ is not being used. I don’t want to use it. But if I remove it I get an error saying “class type expected”. What’s to be done?

Answer 1

catch
{ 
   connection.Close(); 
   return null; 
}
