The class i have used.How can i use this code in asp.net2.0 without getting any error

public static XElement GetGeocodingSearchResults(string address)
{
    // Use the Google Geocoding service to get information about the user-entered address
    // See http://code.google.com/apis/maps/documentation/geocoding/index.html for more info...
    var url = String.Format("http://maps.google.com/maps/api/geocode/xml?  
    address={0}&sensor=false", HttpContext.Current.Server.UrlEncode(address));

    // Load the XML into an XElement object (whee, LINQ to XML!)
    var results = XElement.Load(url);

    // Check the status
    var status =results.Element ("status").Value;
    if (status != "OK" && status != "ZERO_RESULTS")
        // Whoops, something else was wrong with the request...
        throw new ApplicationException("There was an error with Google's Geocoding Service: " + status);

    return results;
}
