WCF小实例以及三种宿主

最近一直在学习WCF相关知识，下面将通过一个小实例对所学的知识进行简单的回顾；本实例是一个简单三层操作数据库，并且也简单实现的三种宿主（控制台宿主，IIS宿主以及Windows服务宿主）的练习；还包含一个双工的功能，下图为程序所创建分层结构图；

首先了解为这个实例所创建的两张简单表；

USE [TestDb]

GO

/****** 对象:  Table [dbo].[T_Account]    脚本日期: 07/31/2013 23:09:27 ******/

SET ANSI_NULLS ON

GO

SET QUOTED_IDENTIFIER ON

GO

CREATE TABLE [dbo].[T_Account](

    [ID] [int] IDENTITY(1,1) NOT NULL,

    [Uid] [int] NULL,

    [Money] [int] NULL,

 CONSTRAINT [PK_T_Account] PRIMARY KEY CLUSTERED

(

    [ID] ASC

)WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY]

) ON [PRIMARY]

GO

USE [TestDb]

GO

/****** 对象:  Table [dbo].[T_User]    脚本日期: 07/31/2013 23:10:00 ******/

SET ANSI_NULLS ON

GO

SET QUOTED_IDENTIFIER ON

GO

CREATE TABLE [dbo].[T_User](

    [ID] [int] IDENTITY(1,1) NOT NULL,

    [Name] [nvarchar](50) COLLATE Chinese_PRC_CI_AS NULL,

    [PassWord] [nvarchar](50) COLLATE Chinese_PRC_CI_AS NULL

) ON [PRIMARY]

接下来简单了解每一层的作用以及一些注意事项；源代码后面直接提供下载；

1：Service.DAL 是针对数据库操作的一些类；

2：Service.DbHelp 为数据库操作提供助手

3：Service.HostTest 为服务提供自宿主的测试；一般在编码时会用到；此层还用到批量寄存的知识；

4：Service.Interface 为契约层，定义的相关开放接口；

5：Service.Model为实体层也是数据契约层；

6：Service.ServerDemo 为实现契约的服务内容；若有逻辑都放在这一层；

7：WcfServiceForIIs 为宿主在IIS内容；

8：WebClient 为客户端为Web形式

9：Windows_HostService为宿主要Windows服务里的内容；

10：WindowsClient、WindowsFormsForHostService、WindowsFormsForIIS分别是对三种寄存宿主进行测试的客户端；

一：注意点批量寄存宿主；把重点的一些配置一及实现代码贴出；

<configuration>

  <configSections>

    <section name="artech.batchingHosting"

             type="Service.HostTest.Configuration.BatchingHostingSettings, Service.HostTest"/>

  </configSections>

  <appSettings>

    <add key="ConnectionString" value="server=.;database=TestDb;uid=sa;pwd=admin"/>

  </appSettings>

  <system.serviceModel>

    <bindings>

      <netTcpBinding>

        <binding name="portSharingBinding" portSharingEnabled="true"></binding>

      </netTcpBinding>

    </bindings>

    <behaviors>

      <serviceBehaviors>

        <behavior name="UsermetadataBehavior">

          <serviceMetadata httpGetEnabled="true" httpGetUrl="http://127.0.0.1:3721/UserService/metadata"/>

        </behavior>

        <behavior name="AccountmetadataBehavior">

          <serviceMetadata httpGetEnabled="true" httpGetUrl="http://127.0.0.1:3721/AccountService/metadata"/>

        </behavior>

        <behavior name="ExcptDivedeBehavior">

          <serviceDebug includeExceptionDetailInFaults="true"/>

        </behavior>

      </serviceBehaviors>

    </behaviors>

    <services>

      <service name="Service.ServerDeom.UserService" behaviorConfiguration="UsermetadataBehavior">

        <endpoint address="http://127.0.0.1:3721/UserService"

                  binding="wsHttpBinding"

                  contract="Service.Interface.IUser"/>

      </service>

      <service name="Service.ServerDeom.AccountService" behaviorConfiguration="AccountmetadataBehavior">

        <endpoint address="http://127.0.0.1:3721/AccountService"

                  binding="wsHttpBinding"

                  contract="Service.Interface.IAccount"/>

      </service>

      <service name="Service.ServerDeom.DuplexTestService">

        <endpoint address="net.tcp://127.0.0.1:3722/DuplexTestService"

                 binding="netTcpBinding"

                 contract="Service.Interface.IDuplexTest" bindingConfiguration="portSharingBinding"/>

      </service>

      <service name="Service.ServerDeom.ExcptDivideService" behaviorConfiguration="ExcptDivedeBehavior">

        <endpoint address="http://127.0.0.1:3723/ExcptDivideService"

                  binding="wsHttpBinding"

                  contract="Service.Interface.IExcptDivide"/>

      </service>

    </services>

  </system.serviceModel>

  <artech.batchingHosting>

    <add type="Service.ServerDeom.UserService, Service.ServerDeom"/>

    <add type="Service.ServerDeom.AccountService, Service.ServerDeom"/>

    <add type="Service.ServerDeom.DuplexTestService, Service.ServerDeom"/>

    <add type="Service.ServerDeom.ExcptDivideService, Service.ServerDeom"/>

  </artech.batchingHosting>

</configuration>

using System.ServiceModel;

using Service.ServerDeom;

using Service.Interface;

namespace Service.HostTest

{

    class Program

    {

        static void Main(string[] args)

        {

            using (ServiceHostCollection hosts = new ServiceHostCollection())

            {

                foreach (ServiceHost host in hosts)

                {

                    host.Opened += (sender, arg) => Console.WriteLine("服务{0}开始监听", (sender as ServiceHost).Description.ServiceType);

                }

                hosts.Open();

                Console.Read();

            }

        }

    }

}

二：宿主要IIS里的注意内容；

新建一个文本文件然后把它的后缀修改成.svc；并在其头部增加一行调用服务的代码；

<%@ ServiceHost Language="C#" Debug="true" Service="Service.ServerDeom.UserService" %>

其配置如下：

<configuration>

  <appSettings>

    <add key="ConnectionString" value="server=.;database=TestDb;uid=sa;pwd=admin"/>

  </appSettings>

  <system.web>

    <compilation debug="true" targetFramework="4.0" />

  </system.web>

  <system.serviceModel>

    <behaviors>

      <serviceBehaviors>

        <behavior>

          <!-- 为避免泄漏元数据信息，请在部署前将以下值设置为 false 并删除上面的元数据终结点 -->

          <serviceMetadata httpGetEnabled="true"/>

          <!-- 要接收故障异常详细信息以进行调试，请将以下值设置为 true。在部署前设置为 false 以避免泄漏异常信息 -->

          <serviceDebug includeExceptionDetailInFaults="false"/>

        </behavior>

      </serviceBehaviors>

    </behaviors>

    <services>

      <service name="Service.ServerDeom.UserService">

        <endpoint binding="ws2007HttpBinding"

                  contract="Service.Interface.IUser"/>

      </service>

    </services>

    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />

  </system.serviceModel>

 <system.webServer>

    <modules runAllManagedModulesForAllRequests="true"/>

  </system.webServer>

</configuration>

把I宿主部署到IIS里；

三：宿主在Windows服务；创建一个Windows服务类库，增加相应的配置以及代码；

<configuration>

  <appSettings>

    <add key="ConnectionString" value="server=.;database=TestDb;uid=sa;pwd=admin"/>

  </appSettings>

  <system.serviceModel>

    <bindings>

      <netTcpBinding>

        <binding name="portSharingBinding" portSharingEnabled="true"></binding>

      </netTcpBinding>

    </bindings>

    <behaviors>

      <serviceBehaviors>

        <behavior name="UsermetadataBehavior">

          <serviceMetadata httpGetEnabled="true" httpGetUrl="http://127.0.0.1:3718/UserService/metadata"/>

        </behavior>

      </serviceBehaviors>

    </behaviors>

    <services>

      <service name="Service.ServerDeom.UserService" behaviorConfiguration="UsermetadataBehavior">

        <endpoint address="http://127.0.0.1:3718/UserService"

                  binding="wsHttpBinding"

                  contract="Service.Interface.IUser"/>

      </service>

    </services>

  </system.serviceModel>

</configuration>

using System.ServiceModel;

using Service.ServerDeom;

using Service.Interface;

namespace Windows_HostService

{

    public partial class Service1 : ServiceBase

    {

        private ServiceHost serviceHost = null; //寄宿服务对象

        public Service1()

        {

            InitializeComponent();

        }

        protected override void OnStart(string[] args)

        {

            try

            {

                serviceHost = new ServiceHost(typeof(UserService));

                if (serviceHost.State != CommunicationState.Opened)

                {

                    serviceHost.Open();

                }

            }

            catch (Exception ex)

            {

            }

        }

        protected override void OnStop()

        {

        }

    }

}

然后安装服务文件的一些属性进行设置，比如服务自动重启，服务名称等；另一些图是对服务进行安装；

若服务安装成功后会在服务里可以看到如下：

客户端调用服务的代码大家就直接看源代码，由于本人也是刚开始学习WCF，实例内容为本人学习所做，若有不足或错误欢迎指正；[源代码下载]
