Share Post as Facebook App on Facebook page

I have been using facebook api to share post on facebook page as facebook app. I have created facebook app. The post also gets shared but the problem is, it is not being posted as a facebook app. Instead it asks user for login and then it shares post as a user. Any help regarding how could I share a post as a Facebook App would be appreciated as I have been trying this for a long time. Thanx in advance friends. The code that I have been using is as follows.

using Facebook;

  protected void CheckAuthorization()
    {
        string authorizationCode = Request.QueryString["code"];
        string access_token = Facebook_GetAccessToken(authorizationCode);
        FacebookShare(access_token);
    }

     private string Facebook_GetAccessToken(string pAuthorizationCode)
    {
        string urlGetAccessToken = "https://graph.facebook.com/oauth/access_token";
        urlGetAccessToken += "?client_id=my app id";
        urlGetAccessToken += "&client_secret=app secret";
        urlGetAccessToken += "&redirect_uri=" + Facebook_GetRedirectUri();
        urlGetAccessToken += "&code=" + pAuthorizationCode;

        string responseData = RequestResponse(urlGetAccessToken);
        if (responseData == "")
        {
            return "";
        }
        NameValueCollection qs = HttpUtility.ParseQueryString(responseData);
        string access_token = qs["access_token"] == null ? "" : qs["access_token"];

        return access_token;
    }

    protected void FacebookShare(string token)
    {
        if (token != null)
        {
            Int64 transactionid = Convert.ToInt64(Cache["transactionid"]);
            string app_id = "my app id";

            string app_secret = "app secret";

            string scope = "offline_access,read_stream,publish_actions,publish_stream,manage_pages,status_update";
            dynamic parameters = new ExpandoObject();

            parameters.link = "my website link";
            parameters.name = "my project name";
            parameters.picture= "my website logo";
            var client = new FacebookClient(token);
            client.Post("/1374775846180409/feed", parameters); // this is my facebook page id where I want to share post.
            Response.Cookies["transaction"].Expires = DateTime.Now;
        }
        else
        {
        }
    }

Regarding above code, I am getting Facebook Authorization code successfully.

You can only ask your user who has logged into your app to post on facebook, apps as such are not allowed to post. You will need a page access token to post as the page, which have permissions to modify the data belonging to a Facebook Page. To obtain a page access token you need to start by obtaining a user access token, for which your user has to be logged into your app and asking for the manage_pages permission scope. Next, you can GET /me/accounts, which will return a page access token for each page that you manage.

This can not be accomplished using offline access or without logging in.
