　　上一个示例程序演示承载于托管代码中的WCF服务,这个示例将演示承载于IIS中的WCF服务.跟上一个示例一样我们先从创建一个WCF服务程序开始.为了方便演示,我们这个项目就在第一个项目的基础上创建.
　　这里先提供完整的项目图做参考
DSC0000.png
　　
　　1.用VS2010打开WcfServiceDemo, 右键WcfServiceDemo解决方案-->Add-->New Project.安照下面的配置填写:
　　 DSC0001.png
　　因为我们的WCF服务承载于IIS中,可以删除program.cs文件,并在IISHostedCalService项目属性中,将Console Application改成 Class Library.因为在删掉program.cs文件后,项目中没有main方法,如果不改成 Class Library,编译会报错.
　　修改方法:右键IISHostedCalService项目-->Property
DSC0002.png
　　
　　2.引入System.ServiceModel.dll. 因为在下面创建服务协定的时候需要用到此类库.右键单击References-->Add References. 在弹出的对话框中,按照下面选择,点击OK按钮.
　　 DSC0003.png
　　3.在应用程序目录中创建 App_Code 子目录。
　　4.现在创建一个服务协定,也就是新建一个接口.为接口应用ServiceContractAttribute特性, 为接口中的4个方法应用OperationContractAttribute特性.
　　这也是WCF协定于普通接口不同之处.带有[ServiceContract]特性的接口说明是WCF公开的协议;带有[OperationContract]特性的方法说明是协议公开的方法. 完整代码如下:
　　在 App_Code 子目录中创建名为 ICalculator.cs 的代码文件
　　ICalculator.cs


DSC0004.gif DSC0005.gif View Code


using System;
using System.ServiceModel;
namespace Microsoft.ServiceModel.Samples
{
[ServiceContract]
public interface ICalculator
{
[OperationContract]
double Add(double n1, double n2);
[OperationContract]
double Subtract(double n1, double n2);
[OperationContract]
double Multiply(double n1, double n2);
[OperationContract]
double Divide(double n1, double n2);
}
}
　　
　　5.实现服务协定,也就是创建一个类,并实现接口的方法.
　　这个类需要继承于ICalculator接口,并实现ICalculator接口的方法.这个类的方法会由WCF服务提供给客户端调用.
　　在 App_Code 子目录中创建名为 CalculatorService.cs 的代码文件
　　CalculatorService.cs


View Code


using System;
using System.ServiceModel;
namespace Microsoft.ServiceModel.Samples
{
public class CalculatorService : ICalculator
{
public double Add(double n1, double n2)
{
return n1 + n2;
}
public double Subtract(double n1, double n2)
{
return n1 - n2;
}
public double Multiply(double n1, double n2)
{
return n1 * n2;
}
public double Divide(double n1, double n2)
{
return n1 / n2;
}
}
}
　　
　　到这一步,服务器端的代码编程已经完成; 这时需要新建两个文件,service.svc,Web.config;我们在浏览器中访问WCF服务时,需要service.svc作为入口,Web.config是IIS的标准配置文件.
　　6.在项目中添加servcie.svc文件.
　　servcie.svc



<%@ServiceHost language=c# Debug="true" Service="Microsoft.ServiceModel.Samples.CalculatorService"%>
　　
　　7.在项目中添加Web.config文件.
　　Webconfig


View Code


<?xml version="1.0"?>
<configuration>
<system.serviceModel>
<services>
<service name="Microsoft.ServiceModel.Samples.CalculatorService" behaviorConfiguration="MyServiceTypeBehaviors" >
<endpoint address=""
binding="wsHttpBinding"
contract="Microsoft.ServiceModel.Samples.ICalculator" />
<!--<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>-->
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="MyServiceTypeBehaviors"  >
<serviceMetadata httpGetEnabled="true"  />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
<system.web>
<compilation targetFramework="4.0"/>
<pages controlRenderingCompatibilityVersion="3.5" clientIDMode="AutoID"/>
</system.web>
</configuration>
　　
　　到这一步,已经完成了所有代码和配置文件,下面需要做的就是把WCF程序配置到IIS就可以了.
　　8.将IISHostedCalService配置到IIS
　　打开IIS-->右键网站-->添加网站. 在弹出的对话框中按照下面的填写
DSC0006.png
　　我本机的IIS版本号是7.5,在创建一个新网站之后,IIS会自动帮你添加一个默认的应用程序池,需要注意的是要确定应用程序池的.NET FrameWork 也是4.0,不然可能会报错.
DSC0007.png
　　到此,WCF服务程序已经配置好,我们看看运行效果:
　　打开IIS-->网站-->WcfCalService-->内容视图-->右键service.svc-->浏览.可以看熟悉的WCF service说明页面.
DSC0008.png
　　点击URL进去看详细的调用信息.

　　9.到这里已经可以像示例一里创建一个客户端调用程序. 我们这里暂时先不创建客户端程序.这里讨论一下WCF和WebService的关系.我们知道WebService是承载于IIS中的,而这里WCF也能承载于IIS中. 在.NET中,其实说白了WebService是WCF的一部分. 就像在.NET FrameWork下,你可以创建控制台应用程序,Windows Form程序, WebForm程序一样; 那怎么样才能在WCF框架内创建一个标准的WebService程序呢? 很简单,只要修改WCF的绑定方式就可以了.
　　将Web.config配置文件下



        <endpoint address=""
binding="wsHttpBinding"
contract="Microsoft.ServiceModel.Samples.ICalculator" />
　　修改成



        <endpoint address=""
binding="basicHttpBinding"
contract="Microsoft.ServiceModel.Samples.ICalculator" />
　　注意binding部分.
　　我们打开浏览器, 重新访问http://szx-station168:8001/service.svc?wsdl
　　看到WSDL已经变成标准WebService描述了.

　　现在的问题是,basicHttpBinding 和wsHttpBinding有什么不同? basicHttpBinding绑定下,WCF发布的是标准的WebService服务,其他开发平台的开发人员可以很方便的调用,也知道应该怎样调用. 但WebService本身也有一些不足,或者不够完善的地方,比如不支持事务,不安全等, 于是.NET提供了一套自己的绑定方式wsHttpBinding, 说了是.NET自己提供的, 功能是多了,效率可能也高了,但因为它还不是国际标准,其他开发平台的编程语言不支持,人家也不知道怎么调用. 所以WCF的跨平台应该分两种情况
　　如果服务提供方和服务调用方都是.NET平台下, 可以使用wsHttpBinding绑定;
　　如果服务提供方和服务调用方是不同的开发平台,一个是.NET,另一个是JAVA,那就只能用basicHttpBinding绑定;
　　而微软现在已经不推荐传统的ASP.NET WebService编程, 推荐使用WCF创建WebService服务.
　　当然WCF还提供了其他的绑定方式,这里不作细究;
　　9.客户端调用程序这里就先不创建了,有兴趣的同学可以参考示例一,过程是一样的.
