This article shows how to create an entity data model to provide the underlying connectivity to the Azure Table data, as well as how to create a WCF Data Service to expose the OData service. You can then consume the feed with any OData client, for example, Power Pivot or an application that uses the CData ADO.NET Provider for OData.
Follow the steps below to create a WCF service application that will provide connectivity to Azure Table data via OData.
In the Connection properties dialog, select the CData Azure Table Data Source and enter the necessary credentials. A typical connection string is below:
AccessKey=myAccessKey;Account=myAccountName;
Account プロパティをストレージアカウント名に設定し、ストレージアカウントのAccessKey を設定して接続します。これらの値を取得する方法は次のとおりです。
See the help documentation for guides to connecting in Visual Studio.
Specify the data source class and configure access to the new WCF Data Service. In the example below, the Access Rule for the entities is set to All. This means that any user will be able to read and modify data.
using System;
using System.Collections.Generic;
using System.Data.Services;
using System.Data.Services.Common;
using System.Linq;
using System.ServiceModel.Web;
using System.Web;
namespace AzureTablesService{
public class AzureTablesDataService : DataService {
public static void InitializeService(DataServiceConfiguration config) {
config.SetEntitySetAccessRule("*", EntitySetRights.All);
config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V3;
}
}
}
You can now use the service from any OData client; for example, Excel Power Pivot.
