如何使用Asp.net通过userID获取Facebook userName？

Question

I am doing an App for android

now I can using "Facebook SDK for Android" to get userID and store in SQL server

The problem is ..

how can I use "Asp.net 4.0" (visual web developer 2010) and "Facebook SDK for .NET" to parse these ID to userName on Server without login button?

I have found some information for using dynamic access token.

but all I have found examples are using visual 2013 , MVC , login button

that is not what i want. I just want a basic aspx.

Do anybody know anything about the question ?

Facebook doesn't provide username. If you are looking for name of user then use this code

Get accesstoken from here. Step 1 : http://narendrajarad.blogspot.in/2014/07/facebook-login-using-javascript.html

Step 2 : Add Facebook reference to your project from nuget packages.

Use this name space :

using Facebook;

Use this code :

_apiKey = "API KEY"
_apiSecret = "SECRET KEY"
var accessToken = "Pass accesstoken stored id hidden field" // check in above link
var client = new FacebookClient(accessToken);
dynamic me = client.Get("me");
Response.Write(me.first_name + "" + me.last_name);
