So during my quest to understand NHibernate I came across a new keyword in C#. (well kind of new, it’s actually an old keyword but used in a different manner specifically for generic types.)
Here’s my problem… When you define a generic type it does not assume it to be either of a reference type or value type. And I do not want to force my type to be a reference type, I want it to be generic. But in a scenario where I have to return an blank or “null” value, that assumption says that the type has to be a reference type…
Here’s what I’m talking about:
The return null statement is making the assumption that T is a reference type. (I don’t want to make this assumption!) In this case I would like to return the default value for reference types and value types without having to create 2 generic types. One for each!
So I can use the default( T ) statement which will return a null for reference types, and a 0 for value types! Problem solved.
