Json数据格式在日常工作中还是非常实用的,只需要Json数据就可以了,如果对Json数据不太了解,那就必须先要对下面就对 进行学习,下面就对Json数据格式的代码进行系统的分析与研究。。#t#
看到另一篇C#解析Json的类 的文章现在json因为轻型,越来越流行,部门内部的数据标准趋向于json,所以开始学习。本次工作内容是要将以下数据解析成.Net可以使用的数据,返回的数据除了header,其他的都是可变的,也就是说结构不是固定的。完全由用户选择,所以选择了生成DataTable。
Json数据格式如下:
- using System;
- using System.Collections.Generic;
- using System.Text;
- using System.Data;
- using System.Web.Script.Serialization;
- namespace Tencent.Itil.Cmsi.Common
- {
- public class GeneralSearchResult
- {
- public Header header = new Header();
- private DataTable fieldDefine = new DataTable();
- /// <summary>
- /// 返回的数据结构定义,无数据
- /// </summary>
- public DataTable FieldDefine
- {
- get { return fieldDefine; }
- set { fieldDefine = value; }
- }
- private DataTable retrunData = new DataTable();
- /// <summary>
- /// 返回的数据,格式为DataTable,结构和FieldDefine中的结构一样
- /// </summary>
- public DataTable RetrunData
- {
- get { return retrunData; }
- set { retrunData = value; }
- }
- /// <summary>
- /// 将json数据转换为定义好的对象,数据转换为DataTable
- /// </summary>
- /// <param name="jsonText"></param>
- /// <returns></returns>
- public static GeneralSearchResult GetTransformData(string jsonText)
- {
- GeneralSearchResult gsr = new GeneralSearchResult();
- JavaScriptSerializer s = new JavaScriptSerializer();
- Dictionary<string, object> JsonData = (Dictionary<string, object>)s.DeserializeObject(jsonText);
- Dictionary<string, object> dataSet = (Dictionary<string, object>)JsonData["dataSet"];
- Dictionary<string, object> header = (Dictionary<string, object>)dataSet["header"];
- Dictionary<string, object> fieldDefine = (Dictionary<string, object>)dataSet["header"];
- Dictionary<string, object> data = (Dictionary<string, object>)dataSet["data"];
- object[] rows = (object[])data["row"];
- gsr.header.Version = header["version"].ToString();
- gsr.header.ErrorInfo = header["errorInfo"].ToString();
- gsr.header.ReturnCode = header["returnCode"].ToString();
- gsr.header.ReturnRows = Convert.ToInt16(header["returnRows"]);
- gsr.header.TotalRows = Convert.ToInt16(header["totalRows"]);
- Dictionary<string, object> dicFieldDefine = (Dictionary<string, object>)dataSet["fieldDefine"];
- foreach (KeyValuePair<string, object> ss in dicFieldDefine)
- {
- gsr.FieldDefine.Columns.Add(ss.Key, typeof(string));
- }
- gsrgsr.RetrunData = gsr.FieldDefine.Clone();
- foreach (object ob in rows)
- {
- Dictionary<string, object> val = (Dictionary<string, object>)ob;
- DataRow dr = gsr.RetrunData.NewRow();
- foreach (KeyValuePair<string, object> sss in val)
- {
- dr[sss.Key] = sss.Value;
- }
- gsr.RetrunData.Rows.Add(dr);
- }
- return gsr;
- }
