C Interface interface Usage Example

This article illustrates the use of C # interface interface. Share it for your reference. The details are as follows:

using System;
//example of interfaces
public class Animals
{
//simple interface
interface IAnimal {
 void Breathes();
}
//interfaces can inherent from other interfaces
interface IMammal : IAnimal {
 int HairLength();
}
//interfaces can implement other interfaces which implemented interfaces
interface IMarsupial : IMammal {
 int PouchSize();
}
//interfaces can implement many other interfaces
interface IGonerMammal : IMammal, IExtinct {
}
interface IExtinct {
 int HowLongExtinct();
}
//classes can implement multiple interfaces
public class TasmanianTiger : IGonerMammal, IMarsupial {
public int PouchSize() { return 2; }
public int HowLongExtinct() { return 28; }
public int HairLength() { return 4; }
public void Breathes() { }
}
  public static void Main(string[] args) {
 Console.Write("The Tasmanian Tiger has been extinct for {0} years", new TasmanianTiger().HowLongExtinct());
  }
}

I hope this article is helpful to everyone's C # programming.
