sequence contains no matching element

[cissemy]

Hi,
I am getiing the error : sequence contains no matching element
From:
Coordinate origin = new Coordinate { Latitude = 37.4217429, Longitude = -122.0844308 };
string address = new GoogleGeocoder().GetAddressFromLatLong(origin.Latitude, origin.Longitude

Everytime i replace { Latitude = 37.4217429, Longitude = -122.0844308 } with different numbers.
It seems working only for Google Geolocation.
Thanks
