FaceBook Graph API: Get Friends of Friends in ASP.Net

Here's the modified code to get Friends of Friends but tis by default does not work and raises the following error

{
   "error": {
      "type": "Exception",
      "message": "(#604) Can't lookup all friends of <UID>. Can only lookup for the logged in user (<MY_UID>), or friends of the logged in user with the appropriate permission"
   }
}

The reason is that unless the friend has allowed APPs to access his friends of friends, it will not work

    {
        FaceBookConnect.API_Key = "Key";
        FaceBookConnect.API_Secret = "Secret";
        if (!IsPostBack)
        {
            string code = Request.QueryString["code"];
            if (!string.IsNullOrEmpty(code))
            {
                string data = FaceBookConnect.Fetch(code, "me/friends");
                FaceBookData facebookData = new JavaScriptSerializer().Deserialize<FaceBookData>(data);
                foreach (FaceBookUser user in facebookData.Data)
                {
                    user.PictureUrl = string.Format("https://graph.facebook.com/{0}/picture", user.Id);
                }
                FaceBookUser friend1 = facebookData.Data[0];
                data = FaceBookConnect.Fetch(code, friend1.Id + "/friends");
                facebookData = new JavaScriptSerializer().Deserialize<FaceBookData>(data);
                gvFriends.DataSource = facebookData.Data;
                gvFriends.DataBind();
            }

        }
    }
    protected void btnFetch_Click(object sender, EventArgs e)
    {
        FaceBookConnect.Authorize("user_photos,friends_photos", Request.Url.AbsoluteUri);
    }
