LinkedIn full profile details using DotNetOpenAuth in MVC4

Question

My MVC4 application allows login using LinkedIn account. I want to pull all details that are avaible from linkedIn of the logged in User. Currently i have done the following.

Answer 1

The response of your request from LinkedIn will be a xml file. The format and fields are mentioned in LinkedIn Profile Fields

For getting email field, you need to modify your request token url as

RequestTokenEndpoint = new MessageReceivingEndpoint("https://api.linkedin.com/uas/oauth/requestToken?scope=r_fullprofile+r_emailaddress", HttpDeliveryMethods.PostRequest),

You can get the fields as required in the following code

 XDocument document = LoadXDocumentFromStream(responseStream); 

Eg : For getting the first name field from the xml file,

var firstName = document.Root.Element("first-name").Value;

Fields like languages, positions, skills etc will be returned as structured objects as part of the profile.

Eg : Language field.

    var Lang = document.Root.Element("languages");                        
    var languages = new List<string>();
    if (Lang != null)
    {
     foreach (var l in Lang.Elements())
        {
          if (l.Element("language") != null && l.Element("language").Element("name") != null)
          {
            languages.Add(l.Element("language").Element("name").Value);
           }
         }
      }

Then you can add fields to "extraData" which can be accessed in the controller.

 extraData.Add("firstName", firstName);
 extraData.Add("languages", lang);
