Generic methods in non-generic types

Question

When you have a method like:

public static T DoSomething<T> ( params T [ ] input )

C# lets you to call it without specifying the T, like:

DoClass.DoSomething ( "1", "2", "3" );

Does the compiler figure out T by what's passed to it?

Is this a good convention (to leave out T in this case)?

Answer 1

Yes, the compiler can infer the generic type parameter in the majority of cases. (One exceptin being when your type is a lambda expression, if I remember right.)

It is generally considered perfectly good practice to omit the generic parameters when they can be inferred. In fact, I would say that it increases readability a certain amount (specifying them is often quite redundant).
