Boolean types

Question

During code review I discovered many places of our C# code that looks like this:

if(IsValid()) {
     return true;
}
else {
     return false;
}

Answer 1

The reasons for the first two examples are entirely human:

• ignorance
• lack of intellectual involvement with one's code
• code was refactored, but only half-way

There's no reason not to (I know it's a double negative) go with return IsValid();
