定义服务契约-创建宿主程序-创建客户端程序访问服务 namespace HelloService{    /// 
    /// 服务契约    /// 
    [ServiceContract]    public interface IHelloService    {        /// 
        /// 服务操作            /// 
        ///         /// 
             [OperationContract]        string  SayHello(string name);    }}

类HelloService继承接口IHelloService

namespace HelloService{   public class HelloService:IHelloService    {        /// 
        /// 打招呼        /// 
        ///         /// 
             public string SayHello(string name)        {            return name + ":say hello!";        }    }}

定义一个客户端

namespace HelloClient{    class Program    {        static void Main(string[] args)        {            using (HelloProxy proxy=new HelloProxy())            {                Console.WriteLine(proxy.Say("KAKA"));                Console.Read();            }        }    }    /// 
    /// 硬编码服务契约    /// 
    interface IService    {        /// 
        /// 服务操作        /// 
        ///         /// 
             [OperationContract]        string Say(string name);    }    /// 
    /// 客户端代理类型    /// 
    class HelloProxy : ClientBase
     
      , IService    {        /// 
      
        /// 硬编码定义绑定        /// 
        public static readonly Binding HelloBinding = new NetNamedPipeBinding();        public static readonly EndpointAddress HelloAddress = new EndpointAddress(new Uri("net.pipe://localhost/Hello"));        public HelloProxy() : base(HelloBinding, HelloAddress) { }        public string Say(string name)        {            //使用Channel属性对服务进行调用            return Channel.SayHello(name);        }           }}
     

 

宿主程序

namespace HelloServiceHost{    class Program    {        static void Main(string[] args)        {            using (MyHelloHost host=new MyHelloHost())            {                host.Open();                Console.Read();            }        }    }    public class MyHelloHost:IDisposable    {        /// 
        /// 定义一个服务对象        /// 
        private ServiceHost _myHost;        public ServiceHost MyHost        {            get { return _myHost; }            set { _myHost = value; }        }        /// 
        /// 定义一个基地址        /// 
        public const string BaseAddress = "net.pipe://localhost";        /// 
        /// 可选地址        /// 
        public const string HelloServiceAddress = "Hello";        /// 
        /// 服务契约实现类型        /// 
        public static readonly Type ServiceType=typeof(HelloService.HelloService);                /// 
        /// 服务契约接口        /// 
        public static readonly Type ContractType=typeof(HelloService.IHelloService);        /// 
        /// 服务定义一个绑定        /// 
        public static readonly Binding helloBinding = new NetNamedPipeBinding();        /// 
        /// 构造服务对象        /// 
        protected void CreateHelloService()        {            //创建服务对象            _myHost = new ServiceHost(ServiceType, new Uri[] { new Uri(BaseAddress)});            //给当前数组对象添加终结点            _myHost.AddServiceEndpoint(ContractType, helloBinding, HelloServiceAddress);        }        /// 
        /// 打开服务        /// 
        public void Open()        {            Console.WriteLine("开始启动服务！");            _myHost.Open();            Console.WriteLine("服务已经启动！");        }        /// 
        /// 构造方法        /// 
        public MyHelloHost()        {            CreateHelloService();        }        /// 
        /// 销毁对象        /// 
        public void Dispose() {            if (_myHost!=null)            {                (_myHost as IDisposable).Dispose();            }        }    }}

 

 

要先启动服务HelloServiceHost

 

再启动客户端
