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...
Datatable dt=new Datatable();StringBuilder JsonString = new StringBuilder(); //Exception Handling if (dt != null && dt.Rows.Count > 0) { JsonString.Append("{ "); JsonString.Append("\"T_blog\":[ "); for (int i = 0; i < dt.Rows.Count; i++) { JsonString.Append("{ "); for (int j = 0...

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)...

本文实例讲述了asp.net使用DataTable构造Json字符串的方法。分享给大家供大家参考，具体如下：
/// <summary>
/// 将datatable转换为json
/// </summary>
/// <param name="dtb"></param>
/// <returns></returns>
private string Dtb2Json(DataTable dtb) {JavaScriptSerializer jss = new JavaScriptSerializer();System.Collections.ArrayList dic = new System.Collections.ArrayList();foreach (DataRow dr in dtb.Rows){Syst...
