Json数据时间格式的处理

方法：

using Newtonsoft.Json;
using Newtonsoft.Json.Converters;//需引入Newtonsoft.Json.dll
public class ConvertHelper
    {
        /// <summary>
        /// 将对象转成json格式并格式化日期：yyyy-MM-dd
        /// </summary>
        /// <param name="jsonObject"></param>
        /// <param name="dateType"></param>
        /// <returns></returns>
        public static string BuildJsonDateString(object jsonObject, string dateType = "yyyy-MM-dd")
        {
            var timeConverter = new IsoDateTimeConverter { DateTimeFormat = dateType };
            return JsonConvert.SerializeObject(jsonObject, Newtonsoft.Json.Formatting.Indented, timeConverter);
        }

        /// <summary>
        /// 将对象转成json格式并格式化时间：yyyy-MM-dd HH:mm:ss
        /// </summary>
        /// <param name="jsonObject"></param>
        /// <param name="dateType"></param>
        /// <returns></returns>
        public static string BuildJsonDateTimeString(object jsonObject, string dateType = "yyyy-MM-dd HH:mm:ss")
        {
            var timeConverter = new IsoDateTimeConverter { DateTimeFormat = dateType };
            return JsonConvert.SerializeObject(jsonObject, Newtonsoft.Json.Formatting.Indented, timeConverter);
        }
    }

 

调用：

public string GetList()
        {
            News_BLL bll = new News_BLL();
            DataTable dt = bll.GetList("").Tables[0];
            var list = Common.ConvertHelper<Model.News_Model.News_ITM>.ConvertToList(dt);
            return Common.ConvertHelper.BuildJsonDateTimeString(list);
        }
