WebClient webClient = new WebClient();
string xml = webClient.DownloadString("http://nominatim.openstreetmap.org/search?city=%22new%20york%22&format=xml");

This should work:

Class for deserializing the json string

public class PlaceInfo
{
    public string place_id { get; set; }
    public string licence { get; set; }
    public string osm_type { get; set; }
    public string osm_id { get; set; }
    public List<string> boundingbox { get; set; }
    public string lat { get; set; }
    public string lon { get; set; }
    public string display_name { get; set; }
    public string @class { get; set; }
    public string type { get; set; }
    public double importance { get; set; }
    public string icon { get; set; }
}

This is the code to get the informations from the website: Format is JSON, i'm using the json serializor of c#

using System.Runtime.Serialization; using System.Runtime.Serialization.Json;

WebClient webClient = new WebClient();
string jsonString = webClient.DownloadString("http://nominatim.openstreetmap.org/search?city=%22new%20york%22&format=json");

//load into memorystream
using (var ms = new MemoryStream(Encoding.Unicode.GetBytes(jsonString)))
{
    //parse
    var ser = new DataContractJsonSerializer(typeof(PlaceInfo[]));
    PlaceInfo[] obj = (PlaceInfo[])ser.ReadObject(ms);
}

the array obj has now all places which where found with that name. for example jsut take the first place which was found obj[0].lon and obj[0].lat

maybe you can use openstreetmaps:

http://nominatim.openstreetmap.org/search?city=%22new%20york%22&format=json

http://nominatim.openstreetmap.org/search?city="---cityname---"&countrycodes="---CountryCode---"&limit=2&format=json

http://wiki.openstreetmap.org/wiki/Nominatim

you can get the result as json or xml
