Hi,

I am really in need of some urgent help please. I am trying to get a new users details from Facebook in C# MVC. I downloaded the NuGet package in Visual Studio and put the code below in my controller.

My questions are:

1. How would I get the code(access token) in C#? Is there a way I can generate one? All the examples I see don't mention how you get it but they just show the code as a parameter in the method.

2. For testing, I created an access token on the Facebook website to see if the user details comes through correctly. I get an error doing this, saying the invalid URL. I searched on Google and I see its because of the localhost url, does anyone know a way around this?

Thanks For all the help.

public ActionResult FacebookCallback(string EmailAddress, string Password, string code)
       {

           var fb = new FacebookClient();

           dynamic result = fb.Post("oauth/access_token", new
           {
               client_id = "XXXXXXXXXXX",
               client_secret = "YYYYYYYYYYYYYYYYYYY",
               redirect_uri = "http%3a%2f%2flocalhost%3a43568%2fRegister",
               code = <big>code</big>
           });

           var accessToken = result.access_token;

           // Store the access token in the session for farther use
           Session["AccessToken"] = accessToken;

           // update the facebook client with the access token so
           // we can make requests on behalf of the user
           fb.AccessToken = accessToken;

           // Get the user's information, like email, first name, middle name etc
           dynamic me = fb.Get("me?fields=first_name,middle_name,last_name,id,email");
           string email = me.email;
           string firstname = me.first_name;
           string middlename = me.middle_name;
           string lastname = me.last_name;

           // Set the auth cookie
           FormsAuthentication.SetAuthCookie(email, false);
           return RedirectToAction("Index", "Home");
       }
