WCF快速上手（二）

服务端是CS程序，客户端(调用者)是BS程序

一、代码结构：

二、服务接口Contract和实体类Domain

INoticeService：

using Domain;

using System;

using System.Collections.Generic;

using System.Linq;

using System.ServiceModel;

using System.Text;

using System.Threading.Tasks;

namespace Contract

{

    /// <summary>

    /// 通知公告

    /// </summary>

    [ServiceContract]

    public interface INoticeService

    {

        /// <summary>

        /// 获取一条公告信息

        /// </summary>

        [OperationContract]

        Notice GetNotice();

    }

}

Notice：

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace Domain

{

    /// <summary>

    /// 通知公告

    /// </summary>

    public class Notice

    {

        /// <summary>

        /// 标题

        /// </summary>

        public string Title { get; set; }

        /// <summary>

        /// 内容

        /// </summary>

        public string Content { get; set; }

        /// <summary>

        /// 数据

        /// </summary>

        public byte[] Data { get; set; }

    }

}

三、服务WcfService和宿主WcfHost

NoticeService：

using Contract;

using Domain;

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace WcfService

{

    /// <summary>

    /// 通知公告服务

    /// </summary>

    public class NoticeService : INoticeService

    {

        /// <summary>

        /// 获取一条公告信息

        /// </summary>

        public Notice GetNotice()

        {

            Notice notice = new Notice();

            notice.Title = "测试标题";

            notice.Content = "测试内容";

            notice.Data = new byte[];

            for (int i = ; i < ; i++)

            {

                notice.Data[i] = (byte);

            }

            return notice;

        }

    }

}

Program：

using System;

using System.Collections.Generic;

using System.Configuration;

using System.IO;

using System.Linq;

using System.ServiceModel;

using System.Text;

using System.Threading;

using System.Threading.Tasks;

using WcfService;

namespace WcfServer

{

    class Program

    {

        static void Main(string[] args)

        {

            string path = AppDomain.CurrentDomain.BaseDirectory + "Service";

            string[] fileArr = Directory.GetFiles(path);

            int port = int.Parse(ConfigurationManager.AppSettings["ServerPort"]);

            foreach (string fileName in fileArr)

            {

                string url = string.Format("http://localhost:{0}/Service/{1}", port, Path.GetFileName(fileName));

                Uri[] uri = new Uri[] { new Uri(url) };

                ServiceHost host = new ServiceHost(typeof(NoticeService), uri);

                host.Open();

            }

            Console.WriteLine("服务成功启动");

            Console.Read();

        }

    }

}

服务端App.config配置：

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

<configuration>

  <startup>

    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />

  </startup>

  <appSettings>

    <add key="ServerPort" value="8998"/>

  </appSettings>

  <system.serviceModel>

    <services>

      <service name="WcfService.NoticeService" behaviorConfiguration="ServiceBehavior" >

        <endpoint  contract="Contract.INoticeService" address="" binding="basicHttpBinding" bindingConfiguration="ServiceBinding">

          <identity>

            <dns value="localhost" />

          </identity>

        </endpoint>

        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />

      </service>

    </services>

    <bindings>

      <basicHttpBinding>

        <binding name="ServiceBinding" sendTimeout="00:00:20" maxReceivedMessageSize="2147483646">

        </binding>

      </basicHttpBinding>

    </bindings>

    <behaviors>

      <serviceBehaviors>

        <behavior name="ServiceBehavior">

          <serviceMetadata httpGetEnabled="true"/>

        </behavior>

      </serviceBehaviors>

    </behaviors>

  </system.serviceModel>

</configuration>

四、客户端

NoticeProxy：

using Contract;

using Domain;

using System;

using System.Collections.Generic;

using System.Linq;

using System.ServiceModel;

using System.Text;

using System.Threading.Tasks;

namespace WcfClient

{

    /// <summary>

    /// 通知公告

    /// </summary>

    public class NoticeProxy : INoticeService

    {

        private ChannelFactory<INoticeService> channelFactory;

        private INoticeService server;

        public NoticeProxy()

        {

            channelFactory = new ChannelFactory<INoticeService>("NoticeService");

            server = channelFactory.CreateChannel();

        }

        /// <summary>

        /// 获取一条公告信息

        /// </summary>

        public Notice GetNotice()

        {

            return server.GetNotice();

        }

    }

}

客户端调用服务：

using Domain;

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using System.Windows.Forms;

using WcfClient;

namespace WinformClient

{

    public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

        }

        private void btnTest_Click(object sender, EventArgs e)

        {

            try

            {

                NoticeProxy proxy = new NoticeProxy();

                Notice notice = proxy.GetNotice();

                MessageBox.Show(notice.Data.Length.ToString());

            }

            catch (Exception ex)

            {

                MessageBox.Show(ex.Message);

            }

        }

    }

}

客户端App.config配置：

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

<configuration>

  <startup>

    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />

  </startup>

  <system.serviceModel>

    <behaviors>

      <endpointBehaviors>

        <behavior name="ServiceBehavior">

          <dataContractSerializer maxItemsInObjectGraph="2147483646"/>

        </behavior>

      </endpointBehaviors>

    </behaviors>

    <bindings>

      <basicHttpBinding>

        <binding name="ServiceBinding"  maxReceivedMessageSize="2147483646">

          <readerQuotas maxArrayLength="65242880" maxStringContentLength="65242880"/>

        </binding>

      </basicHttpBinding>

    </bindings>

    <client>

      <endpoint name="NoticeService" contract="Contract.INoticeService"  address="http://localhost:8998/Service/NoticeService.svc" behaviorConfiguration="ServiceBehavior"  binding="basicHttpBinding" bindingConfiguration="ServiceBinding" />

    </client>

  </system.serviceModel>

</configuration>
