使用json.net 组件 生成JSON字符串，自定义日期格式

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);

            return sb.ToString();
        }

生成的日期格式为一字符串，这样便于客户端处理！
