     在学习IIS服务寄宿时参考了文章：如何在IIS中承载WCF服务http://msdn.microsoft.com/zh-cn/library/ms733766.aspx，并按照上面的教程进行配置，

PS:2011-5-28

不按上面的教程进行配置也是可以的，下面我讲一下我的配置过程。

步骤1：首先创建一个解决方案叫做IISHostWCF。

步骤2：在这个解决方案中创建一个”控制台应用程序“Client来测试我们通过IIS寄宿的服务，然后在创建一个CalcService的“WCF服务库“

步骤3：在创建好WCF服务库以后他会自动帮助我们创建契约IService1.cs（接口）以及契约实现Service1.cs

我们在WCF服务哭下创建一个文件夹叫做App_Code，然后将IService1.cs和Service1.cs都放到这个App_Code文件夹中去。

步骤4：将自动生成的配置文件App.config改名为Web.config（这一步很重要，不然会报错说找不到ServiceHost指定的路径）

步骤5:其他内容可以参照前面。

最后通过http://localhost/IISHostedCalc/Service.svc访问时报错，错误内容为：“由于扩展配置问题而无法提供您请求的页面。如果该页面是脚本，请添加处理程序。如果应下载文件，请添加 MIME 映射。”

解决方法：

以管理员运行命令：

C:/Windows/Microsoft.NET/Framework/v3.0/Windows Communication Foundation/ServiceModelReg.exe -i

运行结果如下图所示：

再次登录 http://localhost/IISHostedCalc/Service.svc，运行经过如下图所示

表明服务没有发布成功，按照提示进行修改，修改以后的Web.config为:

<?xml version="1.0" encoding="utf-8" ?><br /> <configuration><br /> <system.serviceModel><br /> <behaviors><br /> <serviceBehaviors><br /> <behavior name="MyServiceTypeBehaviors" ><br /> <serviceMetadata httpGetEnabled="true" /><br /> </behavior><br /> </serviceBehaviors><br /> </behaviors><br /> <services><br /> <service name="Microsoft.ServiceModel.Samples.CalculatorService" behaviorConfiguration="MyServiceTypeBehaviors" ><br /> <!-- This endpoint is exposed at the base address provided by host: http://localhost/servicemodelsamples/service.svc --><br /> <endpoint address="" binding="wsHttpBinding" contract="Microsoft.ServiceModel.Samples.ICalculator" /><br /> </service><br /> </services><br /> </system.serviceModel><br /> </configuration>

再次登录http://localhost/IISHostedCalc/Service.svc，会出现如下界面

 SvcUtil.exe应用

可以参考ServiceModel 元数据实用工具 (Svcutil.exe)

我们可以在C:/Program Files/Microsoft SDKs/Windows/v6.0A/bin目录下找到SvcUtil.exe，将这个程序拷贝到D盘根目录下，然后打开cmd，切换到d盘根目录下，输入命令：

svcutil.exe http://xuwei/IISHostedCalc/service.svc?wsdl

运行完以后，在d盘根目录下就会自动生成CalculatorService.cs和output.config文件。

在CalculatorService.cs中定义了CalculatorClient这个类，我们在客户端应用程序CalculatorServiceClient中就可以直接通过Calculator这个类创建调用服务的客户端对象。

CalculatorService.cs：

out.config

创建测试客户端

将CalculatorService.cs和out.config拷贝到CalculatorServiceClient项目下。然后添加现有项CalculatorService，添加完以后再添加应用程序配置文件App.config，将out.config中的内容拷贝到App.config中去，Program.cs代码如下：

using System;<br /> using System.Collections.Generic;<br /> using System.Linq;<br /> using System.Text;<br /> namespace CalculatorServiceClient<br /> {<br /> class Program<br /> {<br /> static void Main(string[] args)<br /> {<br /> CalculatorClient client = new CalculatorClient();<br /> // 使用 "client" 变量在服务上调用操作。<br /> Console.WriteLine("x+y={2} when x={0} and y={1}", 1, 2, client.Add(1, 2));<br /> Console.WriteLine("x-y={2} when x={0} and y={1}", 1, 2, client.Subtract(1, 2));<br /> Console.WriteLine("x*y={2} when x={0} and y={1}", 1, 2, client.Multiply(1, 2));<br /> Console.WriteLine("x/y={2} when x={0} and y={1}", 1, 2, client.Divide(1, 2));<br /> Console.Read();<br /> // 始终关闭客户端。<br /> client.Close();<br /> }<br /> }<br /> }<br />

运行这个CalculatorServiceClient控制台应用程序，运行结果如下：
