title: c# - how to get user access token without login from facebook?
body: <p>I want to get user access token(Graph API Explorer) from facebook without login</p>
  
  <p>I tried with app access token but I am unable to get comments for the posts</p>
  
  <p>Code is for app access token:</p>
  
  <pre><code>        string appId = "APP_Id";
          string appSecret = "APP_Secret";
          var fb = new FacebookClient();
          dynamic result = fb.Get("oauth/access_token", new
          {
              client_id = appId,
              client_secret = appSecret,
              grant_type = "client_credentials"
          });
          fb.AccessToken = result.access_token;
          var accessToken = fb.AccessToken;
  </code></pre>
  
  <p>Any ideas? Thanks in advance.</p>
