Interfaces enable you to write generic code for classes which share some functionality but otherwise have no relationship to each other. Consider the following example. The classes Square and Cube both implement the IPower interface but otherwise are not related in any way. This enables us to write a method (MyMethod) which works with any object which implements the IPower interface: using System; interface IPower { int GetPower(int i); } class Square : IPower { public int GetPower(int i) { return i * i; } } class Cube : IPower { public int GetPower(int i) { return i * i * i; } } class Program { static void Main() { Square s = new Square(); MyMethod(s, 2); Cube c = new Cube(); MyMethod(c, 2); Console.ReadKey(); } static void MyMethod(IPower ip, int i) { Console.WriteLine(ip.GetPower(i)); } } The output is: 4 8
