WCF - IIS 托管
在 IIS（Internet 信息服务）中托管 WCF 服务是一个循序渐进的过程。下面详细说明了 IIS 托管，并附有所需的编码和屏幕截图，以便您了解该过程。
步骤 1 − 启动 Visual Studio 2012，然后单击"文件"->"新建"->"网站"。选择"WCF 服务"并将位置设置为 http。这将在 IIS 中托管该服务。单击"确定"。
步骤 2 − 界面背后的代码如下所示。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;
// 注意：您可以使用"重构"菜单上的"重命名"命令来
// 更改代码和配置文件中的接口名称"IService"。
[ServiceContract]
Public interface IService {
[OperationContract]
String GetData(int value);
[OperationContract]
CompositeType GetDataUsingDataContract(CompositeType composite);
// TODO：在此处添加您的服务操作
}
// 使用以下示例中所示的数据契约将
// 复合类型添加到服务操作。
[DataContract]
Public class CompositeType {
Bool boolValue = true;
String stringValue = "Hello ";
[DataMember]
Public bool BoolValue {
get { return boolValue; }
set { boolValue = value; }
}
[DataMember]
Public string StringValue {
get { return stringValue; }
set { stringValue = value; }
}
}
步骤 3 − 类文件背后的代码如下所示。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;
// 注意：您可以使用"重构"菜单上的"重命名"命令一起更改代码、svc 和配置文件中的类名"Service"。
Public class Service : IService {
Public string GetData(int value) {
Return string.Format("You entered: {0}", value);
}
Public CompositeType GetDataUsingDataContract(CompositeType composite) {
if(composite == null) {
thrownewArgumentNullException("composite");
}
if(composite.BoolValue) {
composite.StringValue += "Suffix";
}
return composite;
}
}
步骤 4 − 服务文件 (.svc) 包含服务的名称和文件名背后的代码。此文件用于了解服务。
<%@ ServiceHost Language = "C#" Debug = "true" Service = "Service" CodeBehind = "~/App_Code/Service.cs" %>
步骤 5 − 配置文件中提到了服务器端配置。这里只提到了一个配置为"wsHttpBinding"的端点；我们也可以拥有具有不同绑定的多个端点。由于我们要在 IIS 中托管，因此我们只能使用 http 绑定。

步骤 6 − 您需要提及服务文件名以及配置文件中提到的地址。此处给出了 IIS 的屏幕截图。
单击"开始"→ 运行 → inetmgr，这将打开以下窗口。
步骤 7 − 运行该应用程序，它将生成以下屏幕。
