3. Пример кода для воспроизведения проблемы, пожалуйста указавыйте конкретные значения параметров запроса:

  var temp =  api.Groups.GetLongPollServer(222432549);


BotsLongPollHistoryResponse CallBackResponse = api.Groups.GetBotsLongPollHistory(new BotsLongPollHistoryParams
    { 
    	Key = temp.Key,
        Server = temp.Server,
        Ts = temp.Ts,
    });

var a = Regex.Replace(response.ToString(), "(\"(?:[^\"\\\\]|\\\\.)*\")|\\s+", "$1");

возможно править надо эту регулярку.
@Panuchi глянешь?
