Facebook Integration in MVC 3.0 (.Net)

Now, Time for Facebook Integration in .Net MVC 3.0.

Step 1 :  Download Library package reference of Facebook from NuGet Package Installer.

Step 2 :  import namespace of facebook as like,             

    using facebook;

Step 3 :  This uri method handles Our call back method that will returns from facebook site after Completed Login screen. 

private System.Uri RedirectUri
{
      get
      {
            var uribuilder = new UriBuilder(Request.Url);
            uribuilder.Query = null;
            uribuilder.Fragment = null;
            uribuilder.Path = Url.Action(“FacebookCallBack”);
            return uribuilder.Uri;
      }
}

public ActionResult Facebook()
{
      var fb = new FacebookClient();
      var loginurl = fb.GetLoginUrl(new
            {
                  client_id = “463931757029793”,
                  client_secret = “add31b78281d6ffccc7d1b887f77d9d4″,
                  redirect_uri = RedirectUri.AbsoluteUri,
                  responce_type = “code”,
                  scope = “email,publish_stream,user_hometown,user_website”
            });
      return Redirect(loginurl.AbsoluteUri);
}

Step 4 :  Now, get the Details from facebook Client..

public ActionResult FacebookCallBack(string code)
{
      var fb = new FacebookClient();
      dynamic result = fb.Post(“oauth/access_token”, new
            {
                  client_id = “463931757029793”,
                  client_secret = “add31b78281d6ffccc7d1b887f77d9d4″,
                  redirect_uri = RedirectUri.AbsoluteUri,
                  code = code
            });

      var accessTocken = result[0];
      Session[“AccessTocken”] = accessTocken;
      fb.AccessToken = accessTocken;

      dynamic me = fb.Get(“me?fields=first_name,last_name,id,email”);

      String email = me[3];

      return RedirectToAction(“LoginView”);
}
