Newtonsoft.Json的格式化設置

var jsonSetting = new JsonSerializerSettings {NullValueHandling = NullValueHandling.Ignore};

序列化和反序列化時，忽略null字段

var ArticleList = JsonConvert.DeserializeObject<List<ArticleTask>>(json,jsonSetting);

---------------------------------------

new IsoDateTimeConverter { DateTimeFormat = "yyyy-MM-dd HH:mm:ss" }

序列化時，對時間的格式化設定，使用方法

var json = JsonConvert.SerializeObject(requestData, Formatting.Indented, new IsoDateTimeConverter { DateTimeFormat = "yyyy-MM-dd HH:mm:ss" });
