  ASP.NET MVC 4 beta web api xml post problem

  Mar 06, 2012 07:41 PM|LINK

  I use two programs: the first one posts an xml-package to an asp.net mvc 4 web api project.
  
  The first application:

  const string endpoint = "http://192.168.2.6/WebApi.Test/api/values?format=xml";
  
  var apps = new Apps();
  var applications = new List<Application>();
  var application = new Application();
  
  application.Key = "key";
  application.DisplayName = "name";
  application.InstalledVersion = "2012.1.5.42921";
  application.Environment = "Prod";
  applications.Add(application);
  apps.ApplicationsList = applications;
  
  var httpClient = new HttpClient();
  var mediaType = new MediaTypeHeaderValue("application/xml");
  var requestMessage = new HttpRequestMessage<T>(data, mediaType);
  httpClient.PostAsync(endpoint, requestMessage.Content).Result;

  The second web api application:

  public class ValuesController : ApiController
  {
      // POST /api/values
      public void Post(Apps apps)
      {
          List<Application> applicationsList = apps.ApplicationsList;
          string displayName = applicationsList[0].DisplayName;
          string key = applicationsList[0].Key;
          string environment = applicationsList[0].Environment;
          string hospitalNumber = applicationsList[0].HospitalNumber;
          string installedVersion = applicationsList[0].InstalledVersion;
      }
  }

  I also made 2 seperated classes to store my data in each application:

      public class Apps
      {
          [XmlElement("Application")]
          public List<Application> ApplicationsList { get; set; }
      }
  
      public class Application
      {
          [XmlAttribute("key")]
          public string Key { get; set; }
          [XmlAttribute("zhnr")]
          public string HospitalNumber { get; set; }
          [XmlAttribute("env")]
          public string Environment { get; set; }
          public string DisplayName { get; set; }
          public string InstalledVersion { get; set; }
      }

  The xml-file captured by Wireshark looks fine:

  <?xml version="1.0" encoding="utf-8"?>
  <Apps xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  	<Application key="key" env="Prod">
  		<DisplayName>name</DisplayName>
  		<InstalledVersion>2012.1.5.42921</InstalledVersion>
  	</Application>
  </Apps>

  But the posted object in the ApiController always receives a null-object when a List<Application> is used, can anyone help me?

  The solution is model binding: http://blogs.msdn.com/b/carlosfigueira/archive/2012/02/27/disabling-model-binding-on-asp-net-web-apis-beta.aspx
