(.net - version 3) Authentication Fail through code

[GoogleCodeExporter]

Hi,

I am getting parsing error in authentication using below code

 AccountQuery query = new AccountQuery("https://www.googleapis.com/analytics/v3/management/accounts");
            AnalyticsService service = new AnalyticsService("AnalyticsServiceApi");
            if (!string.IsNullOrEmpty(userName))
            {
                service.setUserCredentials(userName, passWord);
            }

                AccountFeed accountFeed = service.Query(query);
                foreach (AccountEntry entry in accountFeed.Entries)
                {
                    ListViewItem item = new ListViewItem(entry.Title.Text);
                    //item.SubItems.Add(entry.Title.Text);
                    item.SubItems.Add(entry.ProfileId.Value);
                    this.ProfileIds.Items.Add(item);
                }
            }

Its showing me "Parsing failed" issue. Can you please guide me to get profile 
information with version 3 of google Analytics API?
