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]
