无配置实现WCF的调用

在vs中创建空的解决方案

1.先创建一个类库，用来定义服务契约

添加引用：“System.ServiceModel”

HelloService:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.ServiceModel;
namespace HelloService
{
    public class HelloService:IHelloService
    {
        /// <summary>
        /// 打招呼
        /// </summary>
        /// <param name="name"></param>
        /// <returns></returns>
        public string SayHello(string name)
        {
            return name + ":你好";
        }
    }
}

IHelloService:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.ServiceModel;

namespace HelloService
{
    /// <summary>
    /// 服务契约
    /// </summary>
    [ServiceContract]
    public interface IHelloService
    {
        /// <summary>
        /// 服务操作
        /// </summary>
        /// <param name="name"></param>
        /// <returns></returns>
        [OperationContract]
        string SayHello(string name);
    }
}

2.创建一个控制台应用程序

添加引用：“System.ServiceModel”

添加项目引用， 引用项目”HelloService“

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.ServiceModel;
using System.ServiceModel.Channels;
namespace HelloServiceHost
{
    class Program
    {
        static void Main(string[] args)
        {
            using (MyHelloHost Host = new MyHelloHost())
            {
                Host.open();
                Console.Read();
            }
        }
    }

    public class MyHelloHost:IDisposable
    {
        /// <summary>
        /// 定义一个服务对象
        /// </summary>
        private ServiceHost _myhost;

        /// <summary>
        /// 定义一个基地址
        /// </summary>
        public const string BaseAddress = "net.pipe://localhost";
        /// <summary>
        /// 可选地址
        /// </summary>
        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);
        /// <summary>
        ///服务定义一个绑定
        /// </summary>
        public static readonly Binding hellobinding = new NetNamedPipeBinding();
        /// <summary>
        /// 构造服务对象
        /// </summary>
        protected void CreateHelloServiceHost()
        {
            //创建服务对象
            _myhost = new ServiceHost(ServiceType, new Uri[] { new Uri(BaseAddress) });
            //添加终结点
            _myhost.AddServiceEndpoint(ContractType, hellobinding, HelloServiceAddress);
        }

        public ServiceHost Myhost
        {
            get { return _myhost; }
        }

        /// <summary>
        /// 打开服务方法
        /// </summary>
        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()
        {
            CreateHelloServiceHost();
        }

        //销毁服务宿主对象实例
        public void Dispose()
        {
            if (_myhost!=null)
            {
                (_myhost as IDisposable).Dispose();
            }
        }
    }
}

3.创建一个控制台应用程序

添加引用：“System.ServiceModel”

添加项目引用， 引用项目”HelloService“

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.ServiceModel;
using System.ServiceModel.Channels;
using HelloService;
namespace HelloClient1
{
    class Program
    {
        static void Main(string[] args)
        {
            using (HelloProxy proxy = new HelloProxy())
            {
                //利用代理调用服务
                Console.WriteLine(proxy.Say("张三"));
                Console.Read();
            }
        }
    }

    //硬编码定义服务契约
    interface IService
    {
        //服务操作
        [OperationContract]
        String Say(String name);
    }

    class HelloProxy : ClientBase<IHelloService>, IService
    {
        //硬编码定义绑定
        public static readonly Binding HelloBinding = new NetNamedPipeBinding();
        //硬编码定义地址
        public static readonly EndpointAddress HelloAddress = new EndpointAddress(new Uri("net.pipe://localhost/Hello"));

        //构造方法
        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);
        }
    }
}
