    ------------------------windowform承载服务步骤:

    (1)定义契约:

    using System;

    using System.Collections.Generic;

    using System.Linq;

    using System.Text;

    using System.ServiceModel;

    namespace IWpf

    {

        [ServiceContract]

        public interface IUser

        {

            [OperationContract]

            string GetName();

            [OperationContract]

            int GetAge();

        }

    }

    (2)承载契约;

    using System;

    using System.Collections.Generic;

    using System.Linq;

    using System.Text;

    using IWpf;

    namespace wpf承载服务

    {

      public  class wpf:IUser

        {

     

            #region IUser 成员

     

            public string GetName()

            {

                return "郭泽峰";

            }

     

            public int GetAge()

            {

                return 13;

            }

            #endregion

        }

    }

    appconfig:配置契约:

    ?xml version="1.0" encoding="utf-8" ?>

    <configuration>

      <system.serviceModel>

        <services>

          <service name="wpf承载服务.wpf" behaviorConfiguration ="behaviorone">

            <host>

              <baseAddresses>

                <add baseAddress="http://localhost:1234/wpf"/>

              </baseAddresses>

            </host>

            <endpoint address="" binding="basicHttpBinding" contract="IWpf.IUser">

            </endpoint>

          </service>

        </services>

        <behaviors>

          <serviceBehaviors>

            <behavior name="behaviorone">

              <serviceMetadata httpGetEnabled="true"/>

            </behavior>

          </serviceBehaviors>

        </behaviors>

      </system.serviceModel>

    </configuration>

    -------------启动服务;

    using System.ServiceModel;

    namespace wpf承载服务

    {

        public partial class Form1 : Form

        {

            ServiceHost host;

            public Form1()

            {

                InitializeComponent();

            }

            private void button1_Click(object sender, EventArgs e)

            {

                host = new ServiceHost(typeof(wpf));

                host.Open();

            }

     

            private void button2_Click(object sender, EventArgs e)

            {

                host.Close();

            }

        }

    }

    -----------------使用契约;

      ServiceReference1.UserClient u = new ServiceReference1.UserClient();

      MessageBox.Show(u.GetName());

    ---------------------------------------------------------------------------完成;

    --------------

     

     

     

    ---------------通过编程来承载和使用服务;

    --承载服务

     public partial class Form1 : Form

        {

            public Form1()

            {

                InitializeComponent();

            }

            ServiceHost host = null;

            private void button1_Click(object sender, EventArgs e)

            {

                host = new ServiceHost(typeof(wpf));

                //定义绑定协议:

                NetTcpBinding tcpBinding = new NetTcpBinding();

                //定义地址:

                string s = "net.tcp://localhost:3200/gg";//路径随便了;

                host.AddServiceEndpoint(typeof(IWpf.IUser), tcpBinding, s);

                host.Opened += delegate { label1.Text = "已经打开"; };

                host.Closed += delegate { label1.Text = "已经关闭"; };

                host.Open();

            }

     

            private void button2_Click(object sender, EventArgs e)

            {

                if (host.State == CommunicationState.Opened)

                {

                    host.Close();

                }

            }

    -----------------应用客户端:

               //绑定形式:

                NetTcpBinding bind = new NetTcpBinding();

                //地址

                EndpointAddress address = new EndpointAddress("net.tcp://localhost:3200/gg");

                //通道工厂

                ChannelFactory<IWpf.IUser> factory = new ChannelFactory<IWpf.IUser>(bind, address);

                IWpf.IUser user = factory.CreateChannel();

                string s = user.GetName();

                MessageBox.Show(s);

     

    -----------------通信方式:单工(无需等待方法名void,且参数部位out;ref;);请求响应(需要等待);双攻;

    单工:[OperationContract(IsOneWay=true)]即可;

    -------

     

    ---SOA:属于一种基于组件的架构模型;它可以根据需求对松散耦合的粗粒度应用组件

    进行分布式部署,组合和使用。

    SOA的四个特性:

    1.每个服务必须有明确的服务边界;

    2.服务是独立的;

    3.采用标准的契约定义和通信协议;

    4.服务是自解释的;

    //地址:

    http://dddd:5050/;

    net.tcp:dec:3030/myservice;

    net.msmq:localhost/mymsmq;

    -----------------------------------------

    soa的好处:在用户层和一万五层添加了一层服务层,将

    力度比较小的互操作的对象进一步封装,形成粗粒度

    组件,从而达到一种松耦合的状态;

    --------------------------------------------

    tcp:二进制;效率远远高于http;多用于内网传输;

    http:soap;

    ---------------------------------------------

    wcf:

    1.面向服务;

    2.松耦合;

    3,可交互;

    4.整合性;

    -----------------------------------------

    remoting和wevservice区别:

    webservice:不限平台,http协议,基于xml;效率低;无状态;

    remoting:仅限。net平台,网络传输协议(不一定是http),二进制;效率很高;有状态;

    remoting是.net 中用来跨越machine, process, appdomain 进行方法调用的技术,

    ------------messagecontract:控制soap协议的工具;
