Question

Is it possible, and if so how do I override the Contains method of an otherwise normal List<T>, where T is my own, custom type?

Answer 1

To make your own Contains implementation you could create a class that implements the IList interface. That way your class will look like a IList. You could have a real List internally to do the standard stuff.

class MyTypeList : IList<MyType> {     private List<MyType> internalList = new ...;      public bool Contains(MyType instance)     {      }      .... }
