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 interfacespublic class Animals{//simple interfaceinterface IAnimal { void Breathes();}//interfaces can inherent from other interfacesinterface IMammal : IAnimal { int HairLength();}//interfaces can implement other interfaces which implemented interfacesinterface IMarsupial : IMammal { int PouchSize();}//interfaces can implement many other interfacesinterface IGonerMammal : IMammal, IExtinct {}interface IExtinct { int HowLongExtinct();}//classes can implement multiple interfacespublic 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。
