title: Getting Posts from Facebook page with specified fields
body: <p>I developed asp.net web form that takes posts from facebook pages using my facebook application by this code</p>
  
  <pre><code>    var client = new WebClient();
      string oauthUrl = string.Format("https://graph.facebook.com/oauth/access_token?type=client_cred&amp;client_id={0}&amp;client_secret={1}", "appid", "appsecret");
  
      string accessToken = client.DownloadString(oauthUrl).Split('=')[1];
  
      string pageInfo = client.DownloadString(string.Format("https://graph.facebook.com/Mypage?access_token={0} ", accessToken));
      string pagePosts = client.DownloadString(string.Format("https://graph.facebook.com/Mypage/posts?access_token={0} ", accessToken));
  </code></pre>
  
  <p>this code returns <strong><code>all posts with their all fields</code></strong> 
  but I need to <strong><code>choose some fields of them not all</code></strong>
  How can I do that??</p>
