我的MVC4应用程序允许使用LinkedIn帐户登录.我想从登录用户的linkedIn中提取所有可用的详细信息.目前我做了以下工作.

在My AuthConfig.cs中,

  Dictionary<string, object> linkedInExtraData = new Dictionary<string, object>();           
        linkedInExtraData.Add("Icon", "../Images/linkedIn.png");          
        OAuthWebSecurity.RegisterClient(
          client: new App_Start.LinkedInCustomClient("xxxxxxxxxxxx", "yyyyyyyyyyyyyyy"),
          displayName: "LinkedIn",
          extraData: linkedInExtraData);

public class LinkedInCustomClient : OAuthClient
{
    private static XDocument LoadXDocumentFromStream(Stream stream)
    {
        var settings = new XmlReaderSettings

            MaxCharactersInDocument = 65536L
        };
        return XDocument.Load(XmlReader.Create(stream, settings));
    }

            new ServiceProviderDescription
            {
                AccessTokenEndpoint =
                        new MessageReceivingEndpoint("https://api.linkedin.com/uas/oauth/accessToken",
                        HttpDeliveryMethods.PostRequest),
                RequestTokenEndpoint =
                        new MessageReceivingEndpoint("https://api.linkedin.com/uas/oauth/requestToken?scope=r_fullprofile",
                        HttpDeliveryMethods.PostRequest),
                UserAuthorizationEndpoint = …
