Où est l'erreur?

string json = JsonHelper.ObjectToJson(jsonRequest); 
byte[] postdata = System.Text.Encoding.ASCII.GetBytes(json); 

WebClient client = new WebClient(); 
client.Headers.Add("Content-Type", "application/json"); 
string url = string.Format("https://maps.googleapis.com/maps/api/place/add/json?sensor={0}&key={1}", "false", ConfigurationManager.AppSettings["GooglePlacesKey"]); 

byte[] bret = client.UploadData(url,"POST", postdata); 

string sret = System.Text.Encoding.ASCII.GetString(bret); 

JavaScriptSerializer ser = new JavaScriptSerializer(); 
GooglePlecesResponse GoogleResponse = ser.Deserialize<GooglePlecesResponse>(sret);
