纯手工的WCF

一、创建一个类库程序，定义服务协定IOperationService和服务实现OperationService。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
namespace ServiceLib
{
    [ServiceContract]
    public interface IOperationService
    {
        [OperationContract]
        int Add();
        [OperationContract]
        int Multi();
    }
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
namespace ServiceLib
{
    public class OperationService:IOperationService
    {

        public int Add()
        {
            return 5;
        }

        public int Multi()
        {
            return 10;
        }
    }
}

　　二、创建一个控制台程序作为宿主。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
using System.ServiceModel.Channels;
namespace MyServiceHost
{
    class Program
    {
        static void Main(string[] args)
        {
            using (HostService hostService = new HostService())
            {
                hostService.OpenService();
                Console.ReadLine();
            }
        }
        public class HostService:IDisposable{
            /// <summary>
            /// 定义服务对象
            /// </summary>
            private ServiceHost host;

            public HostService(){
                this.CreateOperationService();
            }
            public ServiceHost Host
            {
                get { return host; }
            }
            /// <summary>
            /// 基地址
            /// </summary>
            public const string BASEADDRESS = "net.pipe://localhost";  //或者http、net.tcp 等
            /// <summary>
            /// 备用地址
            /// </summary>
            public const string OPERATIONSERVICEADDRESS = "Operation";
            public static readonly Binding OperationBingding = new NetNamedPipeBinding();
            /// <summary>
            /// 定义服务类型
            /// </summary>
            public static readonly Type ServiceType=typeof(ServiceLib.OperationService);
            /// <summary>
            /// 接口类型
            /// </summary>
            public static readonly Type ContractType = typeof(ServiceLib.IOperationService);
            /// <summary>
            /// 构建服务对象
            /// </summary>
            protected void CreateOperationService()
            {
                host = new ServiceHost(ServiceType, new Uri[] { new Uri(BASEADDRESS) });
                //为服务对象添加终结点
                host.AddServiceEndpoint(ContractType, OperationBingding, OPERATIONSERVICEADDRESS);
            }
            /// <summary>
            /// 释放空间
            /// </summary>
            public void OpenService()
            {
                Console.WriteLine("开始启动服务....");
                host.Open();
                Console.WriteLine("启动服务成功....");
            }
            public void Dispose()
            {
                if (host != null)
                {
                    (host as IDisposable).Dispose();
                }
            }
        }
    }
}

　　三、创建一个控制台程序作为客户端，来测试服务的调用。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
using System.ServiceModel.Channels;
using ServiceLib;
namespace ClientConsole
{
    class Program
    {
        static void Main(string[] args)
        {
            using (OperationProxy proxy = new OperationProxy())
            {
                Console.WriteLine(proxy.Add().ToString());
                Console.WriteLine(proxy.Multi().ToString());
                Console.ReadLine();
            }
        }
        /// <summary>
        /// 硬编码定义服务协定
        /// </summary>
        [ServiceContract]
        interface IService
        {
            [OperationContract]
            int Add();
            [OperationContract]
            int Multi();
        }

        class OperationProxy : ClientBase<IOperationService>, IService
        {
            /// <summary>
            /// 硬编码定义绑定
            /// </summary>
            public static readonly Binding OperationBinding = new NetNamedPipeBinding();
            public static readonly EndpointAddress OperationAddress = new EndpointAddress(new Uri("net.pipe://localhost/Operation")); //Operation 表示宿主中定义的备选地址
            public OperationProxy()
                : base(OperationBinding, OperationAddress)
            {
            }
            public int Add()
            {
                return Channel.Add();
            }
            public int Multi()
            {
                return Channel.Multi();
            }
        }
    }
}
