a. 服务端1.契约 使用了继承using System;using System.ServiceModel;namespace WCF.Chapter2.InheritanceReworked.Host{    [ServiceContract]    public interface IHuman    {        [OperationContract]        string HumanSay();    }    [ServiceContract]    public interface IMan : IHuman    {        [OperationContract]        string ManSay();    }    [ServiceContract]    public interface IWoman : IHuman    {        [OperationContract]        string WomanSay();    }}2.服务实现 实现了自己的具体的接口using System;using System.ServiceModel;namespace WCF.Chapter2.InheritanceReworked.Host{    public class ManService : IMan    {        public string HumanSay()        {            return " 我是人，我会思考！";        }        public string ManSay()        {            return "我是男人，我力气比较大！";        }    }    public class WomanService : IWoman    {        public string HumanSay()        {            return " 我是人，我会思考！";        }        public string WomanSay()        {            return "我是女人，我爱漂亮！";        }    }}3.服务终结点配置
     
       
          
             
                
                   
           
            
                  
                 
               
                    
                
                   
           
            
                  
                 
               
            
               
             
                
                   
                  
               
            
         
      
     4.服务寄宿开启using System;using System.ServiceModel;namespace WCF.Chapter2.InheritanceReworked.Host{    class Program    {        static void Main(string[] args)        {            using (ServiceHost hostMan = new ServiceHost(typeof(ManService)))            {                hostMan.Opened += delegate                {                    Console.WriteLine("Man服务已开启...");                };                hostMan.Open();                using (ServiceHost hostWoman = new ServiceHost(typeof(WomanService)))                {                    hostWoman.Opened += delegate                    {                        Console.WriteLine("Woman服务已开启...");                    };                    hostWoman.Open();                    Console.ReadLine();                }                Console.WriteLine("Woman服务已关闭...");                Console.ReadLine();            }            Console.WriteLine("Man服务已关闭...");        }    }}b. 客户端1.客户端等效契约 除了命名空间不一样其他的都一样using System;using System.ServiceModel;namespace WCF.Chapter2.InheritanceReworked.Client{    [ServiceContract]    public interface IHuman    {        [OperationContract]        string HumanSay();    }    [ServiceContract]    public interface IMan : IHuman    {        [OperationContract]        string ManSay();    }    [ServiceContract]    public interface IWoman : IHuman    {        [OperationContract]        string WomanSay();    }}2.人类代理 男人和女人在服务端都实现了他，所以既可以是男人代表人，也可以是女人去代表人using System;using System.ServiceModel;namespace WCF.Chapter2.InheritanceReworked.Client{    public class HumanProxy : ClientBase
     
      , IHuman    {        public HumanProxy()        { }        public HumanProxy(string configurationName) :            base(configurationName)        { }        public string HumanSay()        {            return base.Channel.HumanSay();        }    }}3.由2的结论这里给出终结点配置
