Google API request for extended resource

Question

I upload contacts from the application to Google Contacts with an external code named extcod.

ExtendedProperty property = new ExtendedProperty();
property.Name = "http://www.example.com/schemas/2005#mycal.extcod";
property.Value = item["ana_id"].ToString();
newEntry.ExtendedProperties.Add(property);

Now I would like to search the extended extcod interface in Google Contacts. but I can't figure out how to use the class ContactsQueryto set up the where clause using ExtendedProperty.

You will need to use the ContactQuery "Query" attribute: http://code.google.com/p/google-gdata/source/browse/trunk/clients/cs/src/core/feedquery.cs#361
