由于c#没有多继承，所以用接口可以实现多继承
interface IWoman { void GetSon(); } interface IMan { void Publish(); } class Program : IMan,IWoman { static void Main(string[] args) { Program p = new Program(); p.Publish(); p.GetSon(); Console.ReadKey(); } public void Publish() { Console.WriteLine("IMan接口 Publish"); } public void GetSon() { Console.WriteLine("IWoMan接口 GetSon"); } }
