Answer 1

public static string ToJson(object obj, bool formatjson)
{
StringBuilder sb = new StringBuilder();
StringWriter sw = new StringWriter(sb);

        IsoDateTimeConverter idtc = new IsoDateTimeConverter();
        idtc.DateTimeFormat = "yyyy-MM-dd HH:mm:ss";

        JsonSerializer serializer = new JsonSerializer();
        serializer.Converters.Add(idtc);
        JsonWriter jw = new JsonTextWriter(sw);

        if (formatjson)
        {
            jw.Formatting = Formatting.Indented;
        }

        serializer.Serialize(jw, obj);

        //JsonConvert.SerializeObject(dt, idtc).ToString();

        return sb.ToString();
    }
