本文实例讲述了C#接口interface用法。分享给大家供大家参考。具体如下：

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()); } }

希望本文所述对大家的C#程序设计有所帮助。
