c# google weather xml getting

我想从我使用这个http://www.google.com/ig/api?weather=获取天气

    // load xml result from Google weather
    var addr = WebUtility.HtmlEncode("http://www.google.com/ig/api?weather=vilnius&hl=lt");
    XDocument xd = XDocument.Load(addr);

// navigate to current conditions node
var current_conditions = from currentCond in xd.Root.Descendants("current_conditions")
select currentCond;
// navigate to Forecast info node
var forcastInfo = from forecastinfo in xd.Root.Descendants("forecast_information")
select forecastinfo;

我使用网址http://www.google.com/ig/api?weather=vilnius&hl=lt但信息是英文的，我找不到问题，请帮忙:)
