Adding generic object to generic list in C#

Question

I have class where the relevant part looks like

class C {
    void Method(SomeClass obj) {
        list.Add(obj);
    }
    List l         


        

Answer 1

I don't think you can do this in C#... you would have to add the type parameter to the class:

class C {
    void Method(SomeClass obj) {
        list.Add(obj);
    }
    List> list = new List>();
}

The other option would be to use an interface:

class C {

    void Method(T obj)
         where T : ISomeClass {
        list.Add(obj);
    }
    List list = new List();
}
