使用WindowsService为宿主实装WCF 服务

由于需要，需要把WCF服务宿主在windows service 中，下面说明一下，Demo的步驟：
1. 写WCF服务

创建一个接口类，与一个实现类。接口类上打上[ServiceContract]标签，需要暴露的服务方法上打上[OperationContract]

（注意：增加System.ServiceModel 类的引用

代码如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
using System.Configuration;

namespace Angelia.WinService.DemoWinService
{
[ServiceContract]
interface IMyService
{
[OperationContract]
string OutputString(string paramString);

}

public class MyService : IMyService
{
实现接口方法的代码
}
}

增加app.config文件,增加WCF服务信息的结点如下：

<system.serviceModel>
<services>
<service name="Angelia.WinService.DemoWinService.MyService" --服务的类名 behaviorConfiguration="basicBehavior">
<host>
<baseAddresses>
<add baseAddress="http://localhost:8999/MyService"/>
</baseAddresses>
</host>
<endpoint address="http://localhost:8999/MyServiceService" --指定服务的位置
contract="Angelia.WinService.DemoWinService.IMyService" --接口类的名字，即是contract
binding="basicHttpBinding" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="basicBehavior">
<serviceMetadata httpGetEnabled="true" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>

2.创建Window Service ,把WCF服务放在window Service中

找到visual studio 自动帮助创建的OnStart方法

protected override void OnStart(string[] args)
{
ServiceHost host = new ServiceHost(typeof(MyService));  --把WCF的service宿主在这里
host.Open();  --打开服务。
}

增加安装服务类。
在服务类的设计面板上，点鼠标右键，然后在弹出的菜单上，点add installer项，然后一个叫ProjectInstaller类增加成功。

在设计面板上有两个控件：

一个叫serviceProcessInstaller1.选中它，到属性窗口，选择account，可以选择windows servcie的login用户身份，一般选择NetworkService.

一个叫ServiceInstaller1.选中它到属性窗口，可以设置服务名，启动类型等关于服务的一些设置。

3. 安装或卸载Windows 服务
执行下面的批处理文件安装服务。

set WindowsServiceExeName="MyService.exe"  --第一步中编译出来的exe文件。
set WindowsServiceName="MyServiceDemo"     --在安装类中设置的服务的名字。

@ECHO.
@ECHO -----------------------------------------------------------------
@ECHO Installing Services %WindowsServiceName%
@ECHO -----------------------------------------------------------------
@ECHO.

if Exist %WindowsServiceExeName% installutil %WindowsServiceExeName%
@if errorlevel 1 goto :error

httpcfg set urlacl -u http://+:8999/IngrianService/ -a D:(A;;GX;;;NS)

@ECHO.
@ECHO -----------------------------------------------------------------
@ECHO Start the services for %WindowsServiceName%
@ECHO -----------------------------------------------------------------
@ECHO.
net start %WindowsServiceName%
@if errorlevel 1 goto :error

@ECHO.
@ECHO ----------------------------------------
@ECHO InstallServices.bat Completed
@ECHO ----------------------------------------
@ECHO.

@REM  ----------------------------------------
@REM  Restore the command prompt and exit
@REM  ----------------------------------------
@goto :exit

@REM  -------------------------------------------
@REM  Handle errors
@REM
@REM  Use the following after any call to exit
@REM  and return an error code when errors occur
@REM
@REM  if errorlevel 1 goto :error
@REM  -------------------------------------------
:error
@ECHO An error occured in InstallServices.bat - %errorLevel%
@PAUSE
@exit errorLevel

@REM  ----------------------------------------
@REM  The exit label
@REM  ----------------------------------------
:exit

popd
set pause=
PAUSE
echo on

卸载Windows 服务

set WindowsServiceExeName="MyService.exe"  --第一步中编译出来的exe文件。
set WindowsServiceName="MyServiceDemo"     --在安装类中设置的服务的名字。
@ECHO
@ECHO -----------------------------------------------------------------
@ECHO Stop the services for %WindowsServiceName%
@ECHO -----------------------------------------------------------------
@ECHO
.net stop %WindowsServiceName%
@ECHO
@ECHO -----------------------------------------------------------------
@ECHO Uninstalling Services for %WindowsServiceName%@ECHO -----------------------------------------------------------------
@ECHO
if Exist %WindowsServiceExeName% installutil /u %WindowsServiceExeName%
@if  errorlevel 1 goto :error
@ECHO
@ECHO ----------------------------------------
@ECHO UninstallServices.bat Completed
@ECHO ----------------------------------------
@ECHO
@REM ----------------------------------------
@REM Restore the command prompt and exit
@REM ----------------------------------------
@goto :exit
@REM -------------------------------------------
@REM Handle errors
@REM
@REM Use the following after any call to exit
@REM and return an error code when errors occur
@REM
@REM if errorlevel 1 goto :error
@REM -------------------------------------------
:error
@ECHO  An error occured in InstallServices.bat - %errorLevel%
@PAUSE
@exit errorLevel
@REM ----------------------------------------
@REM The exit label
@REM ----------------------------------------
:exit
popd
set pause=PAUSE
echo on

3.客户端调用WCF服务

首先增加service reference.把服务启动后，输入服务地址，也就是第一步中配置文件中的地址，

（注意第一步中的locahost要改成机器的IP地址）

添加完引用后。app.config中有如下代码：

<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_IIngrianService" closeTimeout="00:01:00"
openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536"
messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
useDefaultWebProxy="true">
<readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
maxBytesPerRead="4096" maxNameTableCharCount="16384" />
<security mode="None">
<transport clientCredentialType="None" proxyCredentialType="None"
realm="" />
<message clientCredentialType="UserName" algorithmSuite="Default" />
</security>
</binding>
</basicHttpBinding>
</bindings>
<client>
<endpoint address="http://10.1.24.143:8999/IngrianService" binding="basicHttpBinding"
bindingConfiguration="BasicHttpBinding_IIngrianService" contract="ServiceReference1.IIngrianService"
name="BasicHttpBinding_IIngrianService" />
</client>
</system.serviceModel>

调用服务方法：如下是调用代码：

static void Main(string[] args)
{
ServiceReference1.MyServiceClient client = new ServiceReference1.MyServiceClient();
string text = client.OutputString("dsfsdfsdfsdf");
Console.WriteLine("string: " + text);

Console.Read();
}
