[Yatin]

Hi,

I am very new to opensocial (Orkut) and trying to access the basic
services provided by open social .net APIs to access inbasic
information from orkut.

I am getting 401 error every time i am sending a request to orkut
sandbox. Below is the code for the same. Please help me in finding the
reason.

using System;
using org.opensocial.client;
using org.opensocial.data;

public partial class _Default : System.Web.UI.Page
{
    public class User
    {
        public User(string Id, string AlbumId, string MediaItemId,
string AppId)
        {
            this.Id = Id;
            this.AlbumId = AlbumId;
            this.MediaItemId = MediaItemId;
            this.AppId = AppId;
        }

        public string Id;
        public string AlbumId;
        public string MediaItemId;
        public string AppId;
    }
    protected void Page_Load(object sender, EventArgs e)
    {
        string strUserName = "DummyUser";
        string strSecretKey = "SecretKey";
        string strCustomerkey = "CustomerKey";

        User user = new User(strUserName, null, null, null);
        OpenSocialClient client = new OpenSocialClient("orkut.com");
        client.setProperty(OpenSocialClient.Properties.REST_BASE_URI,
