Fetching Hosting Services Name Using Windows Azure Management API

TheWindows Azure Management API is a REST based API and allows you to perform almost all management level tasks with an Azure subscription.

Any client making a call to an Azure portal using a Management API has to authenticate itself before making a call. Authenticating being done between Azure portal and client calling REST based Azure Management API through the certificates.

Very first let us create a class representing HostedService. There is property representing name of hosted service.

        public  class HostedServices
        {
            public string serviceName { get; set; }
        }

Essentially you need to perform four steps:

1. You need to create a web request to your subscription id.
   
   
    
2. While making request you need to make sure you are calling the correct version and adding the cross ponding certificate of your subscription.
   
   
   
   Note: I have uploaded debugmode.cer to my azure portal at subscription level.
    
3. Get the stream and convert response stream in string
   
   
   
   You will get the XML response in the following format:
   
   
    
4. Once XML is there in form of string you need to extract ServiceName from XML element using LINQ to XML.
   
   
   

On running you should get all the hosted service. For me there is only one hosted service debugmode9 under my Azure subscription.

            request.ClientCertificates.Add

                            (@"D:\debugmode.cer"));
             var response = request.GetResponse().GetResponseStream();
             var xmlofResponse = new StreamReader(response).ReadToEnd();
 
             XDocument doc = XDocument.Parse(xmlofResponse);

             var servicesName = from r in doc.Descendants(ns + "HostedService")
                                select new HostedServices
                                {
                                    serviceName = r.Element(ns + "ServiceName").Value
                                };           
             foreach (var a in servicesName)
             {
                 Console.WriteLine(a.serviceName);
             }                   
             Console.ReadKey(true);
         }
     }
