管理员如何访问粉丝页面

protected void Page_Load(object sender, EventArgs e)
{
    if (Request["Code"] == null)
    {
       Response.Redirect(string.Format("https://graph.facebook.com/oauth/authorize?client_id={0}&redirect_uri={1}&scope={2}", app_id, Request.Url.AbsoluteUri, scope)); 
    }
}
private void CheckAuthorization()
{
    Dictionary<string, string> tokens = new Dictionary<string, string>();
    string url = string.Format("https://graph.facebook.com/oauth/access_token?client_id={0}&redirect_uri={1}&scope={2}&code={3}&client_secret={4}", app_id, Request.Url.AbsoluteUri, scope, Request["Code"], app_secret);
    HttpWebRequest request = System.Net.WebRequest.Create(url) as HttpWebRequest;
    using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
    {
        StreamReader reader = new StreamReader(response.GetResponseStream());
        string vals = reader.ReadToEnd();
        foreach (string token in vals.Split('&'))
        {
            tokens.Add(token.Substring(0, token.IndexOf("=")), token.Substring(token.IndexOf("=") + 1, token.Length - token.IndexOf("=") - 1));
        }
    }
    string access_token = tokens["access_token"];
    dynamic messagePost = new ExpandoObject();
    messagePost.access_token = access_token;
    messagePost.picture = "picture";
    messagePost.link = "link";
    messagePost.name = "name";
    messagePost.caption = "caption";
    messagePost.description = "description ";
    FacebookClient app = new FacebookClient(access_token);
    app.Post("/PAGE ID/feed", messagePost);
