WCF-IISホスティング

IIS（インターネットインフォメーションサービス）でWCFサービスをホストすることは、段階的なプロセスです。IISホスティングは、プロセスを理解するためのスクリーンショットだけでなく、必要なコーディングとともに詳細に以下に示されています。

Step 1− Visual Studio 2012を起動し、[ファイル]→[新規]→[Webサイト]をクリックします。「WCFサービス」と場所をhttpとして選択します。これにより、IISでサービスがホストされます。[OK]をクリックします。

Step 2 −インターフェースの背後にあるコードを以下に示します。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;

// NOTE: You can use the "Rename" command on the "Refactor" menu to 
// change the interface name "IService" in both code and config file 
// together.

[ServiceContract]
Public interface IService {
   [OperationContract]
   String GetData(int value);

   [OperationContract]
   CompositeType GetDataUsingDataContract(CompositeType composite);

   // TODO: Add your service operations here
}

// Use a data contract as illustrated in the sample below to add 
// composite types to service operations.

[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; }
   }
}

Step 3 −クラスファイルの背後にあるコードを以下に示します。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;

// NOTE: You can use the "Rename" command on the "Refactor" menu to 
// change the class name "Service" in code, svc and config file 
// together.

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;
   }
}

Step 4−サービスファイル（.svc）には、サービスの名前とファイル名の背後にあるコードが含まれています。このファイルは、サービスについて知るために使用されます。

<%@ ServiceHost Language = "C#" Debug = "true" Service = "Service" 
   CodeBehind = "~/App_Code/Service.cs" %>

Step 5−サーバー側の構成は構成ファイルに記載されています。ここでは、「wsHttpBinding」に構成されているエンドポイントが1つだけ言及されています。バインディングが異なる複数のエンドポイントを持つこともできます。IISでホストするため、httpバインディングのみを使用する必要があります。
