C#生成Json格式文档

1、随笔- 14 文章- 0 评论- 5 C#生成JSON数据格式的函数使用说明： 对List 集合使用的方法： List objList = objAction.GetCODE_MByList(objTbl); string JsonSource = JSONHelper.ToJSON(objList); /当前页记录转成JSON格式 但有个问题： 日期型数据谁转换成：这样的数据！？不知道谁碰到过没有！ 对数据集的使用如：DataSet,DataTable JSONHelper jsonHelp = new JSONHelper(); jsonHelp.success = true; jsonH

2、elp.totlalCount = getPrjListCount(); foreach (DataRow dr in dsResult.Tables0.Rows) . jsonHelp.AddItem(PRJ_ID, drPRJ_ID.ToString(); jsonHelp.AddItem(PRJ_NAME, drPRJ_NAME.ToString(); jsonHelp.AddItem(DEP_ID, drDEP_ID.ToString(); jsonHelp.AddItem(PRJ_MANID, drPRJ_MANID.ToString(); jsonHelp.AddItem(PRJ_

3、STATE, drPRJ_STATE.ToString(); if (drPRJ_STARTDATE != DBNull.Value) . jsonHelp.AddItem(PRJ_STARTDATE, Convert.ToDateTime(drPRJ_STARTDATE).ToString(yyyy/MM/dd); else . jsonHelp.AddItem(PRJ_STARTDATE, string.Empty); if (drPRJ_ENDDATE != DBNull.Value) . jsonHelp.AddItem(PRJ_ENDDATE, Convert.ToDateTime(

4、drPRJ_ENDDATE).ToString(yyyy/MM/dd); else . jsonHelp.AddItem(PRJ_ENDDATE, string.Empty); jsonHelp.AddItem(PRJ_MEMO, drPRJ_MEMO.ToString(); jsonHelp.AddItem(CODE_NAME, drCODE_NAME.ToString(); jsonHelp.AddItem(DEP_NAME, drDEP_NAME.ToString(); jsonHelp.AddItem(USER_NAME, drUSER_NAME.ToString(); jsonHel

5、p.ItemOk(); string strResult = jsonHelp.ToString(); /#JSONHelp.cs源码#/ using System;using System.Collections;using System.Collections.Generic; using System.Text; using System.Web.Script.Serialization;namespace mon. /*/ / JSONHelper 的摘要说明 / public class JSONHelper . /对应JSON的singleInfo成员 p

6、ublic string singleInfo = string.Empty; protected string _error = string.Empty; protected bool _success = true; protected long _totalCount = 0; protected System.Collections.ArrayList arrData = new ArrayList(); public JSONHelper() . public static string ToJSON(object obj) . JavaScriptSerializer seria

7、lizer = new JavaScriptSerializer(); return serializer.Serialize(obj); public static string ToJSON(object obj, int recursionDepth) . JavaScriptSerializer serializer = new JavaScriptSerializer(); serializer.RecursionLimit = recursionDepth; return serializer.Serialize(obj); /对应于JSON的success成员 设置success

8、为TURE，代表成功#region 设置success为TURE，代表成功 public bool success . get . return _success; set . /如设置为true则清空error if (success) _error = string.Empty; _success = value; #endregion /对应于JSON的error成员 public string error . get . return _error; set . /如设置error，则自动设置success为false if (value != ) _success = false;

9、_error = value; public long totlalCount . get . return _totalCount; set . _totalCount = value; /重置，每次新生成一个json对象时必须执行该方法 public void Reset() . _success = true; _error = string.Empty; singleInfo = string.Empty; arrData.Clear(); .#region public void AddItem(string name, string value) . arrData.Add( +

10、name + : + + value + ); #endregion public void ItemOk() . arrData.Add(); /序列化JSON对象，得到返回的JSON代码 public override string ToString() . StringBuilder sb = new StringBuilder(); sb.Append(); sb.Append(totalCount: + totlalCount.ToString() + ,); sb.Append(success: + _success.ToString().ToLower() + ,); sb.Append(error: + _error.Replace(, ) + ,); sb.Append(singleInfo: + singleInfo.Replace(, ) + ,); sb.Append(data:); int index = 0; sb.Append(); if (arrData.Count = 0) . sb.Append(); else . foreach (string val in arrData) . index+; if (val != ) . sb.Append(val + ,); else . sb = sb.
