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

The reason you can't do:

return command.ExecuteScalar() as Int32? ?? throw new Exception();

Is because throwing an exception is a statement, not an expression.

If you're just looking to shorten the code a little bit, perhaps this:

var result = command.ExecuteScalar() as Int32?;
if(result.HasValue) return result;
throw new Exception();

No need for the else.
