1.string res = DataTableToJson.DataTable2Json(dt);讲DataTable转换为json字符串 http://www.365mini.com/page/jquery_parsejson.htm 2.jQuery.parseJSON()函数用于将格式完好的JSON字符串转为与之对应的JavaScript对象 var res = $.parseJSON(data).ds原文：http://www.cnblogs.com/zhoumeng780/p/4585124.html

前端用的jqueryUI框架获取json格式数据绑定显示表格。后端通过WebService获取的数据是DataTable。现将获取DataTable转Json，也支持将数据集合转Json。一。项目中引用：Newtonsoft.Json 二。功能代码，很简单：using System;using System.Data;namespace WebApplication1.Common{ public class DataTableToModel { public static DataTable GetData() { DataTable dt = new DataTable(); dt.Colu...

1、将dt序列化成json，放到前台的隐藏控件【hidBoundary】中： 代码如下: string json = JsonConvert.SerializeObject(dtTemp); this.hidBoundary.Value = json; 需要引用Newtonsoft.Json.dll 2、从前台隐藏空间中取得dt中的数据 代码如下: var boundaryDiv = $(#hidBoundary); if (boundaryDiv != undefined && boundaryDiv.length != 0) { var jsonString = boundaryDiv.val(); _jsonBoundary = jQuery.parseJSON(jsonString)...

我有一个带有4列的DataTable.
