var
is simply a shortcut for the actual type of the right-side expression.
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...
string 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!)
XElement results = XElement.Load(url);
// Check the status
string 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;
}
BUT LINQ to XML
(and whole LINQ
functionality) is only available in .NET 3.5 and above. You should either upgrade to .NET 3.5 or switch to System.Xml
