Is it possible to use operator ?? and throw new Exception()?

Question

I have a number of methods doing next:

var result = command.ExecuteScalar() as Int32?;
if(result.HasValue)
{
   return result.Value;
}
else
{
   throw new Ex         


        

Answer 1

If you just want an exception when the returned value isn't an Int32 then do this:

return (int)command.ExecuteScalar();

If you want to throw your own custom exception then I'd probably do something like this instead:

int? result = command.ExecuteScalar() as int?;
if (result == null) throw new YourCustomException();
return result.Value;
