Generic method with type constraints or base class parameter

Question

If I write a method accepting a parameter which derives from a BaseClass (or an interface), as far as I know there are two ways to achieve that:

voi         


        

Answer 1

In the examples included in your question, there isn't much difference between the generic and the non-generic version. But here are some other examples of method signatures that can't be expressed without generics:

T MyMethod(T obj) where T : BaseClass { ... } 
void MyMethod(T obj1, T obj2) where T : BaseClass { ... } 
void MyMethod(T obj, List list) where T : BaseClass { ... }
