Operator && cannot be applied to operands of type bool and short : Error

At least we get an error message when we do stuff like that in C#.

If you'd have done that in C the compiler would have accepted it - TTT.PaymentStatusID would have been assigned 1 which would then be regarded as a 'true' expression - and you'd have been hard pressed to find it later on when the program was malfunctioning!

To avoid this sort of error, many C programmers write the expressions the other way around:

 1 == TTT.PaymentStatusID 

but (thankfully) that is unnecessary in C# :)
