1.这里下载:http://www.newtonsoft.com/products/json/
安装:
解压下载文件,得到Newtonsoft.Json.dll
在项目中添加引用
2.引入命名空间
创建一个DataTable对象：
DataTable dt = new DataTable();
DataColumn dcName = new DataColumn("Name");
DataColumn dcAge = new DataColumn("Age");
DataColumn dcCity = new DataColumn("City");
dt.Columns.Add(dcName);
dt.Columns.Add(dcAge);
dt.Columns.Add(dcCity);
for (int i = 0; i < 10; i++)
{
DataRow dr = dt.NewRow();
dr[0] = "Name" + i;
dr[1] = "Age" + i;
dr[2] = "City" + i;
dt.Rows.Add(dr);
}
转换为json格式：
string json = JsonConvert.SerializeObject(dt);
Console.WriteLine(json);
json格式转换为DataTable：
DataTable dt1 = JsonConvert.DeserializeObject<DataTable>(json); for (int i = 0; i < dt1.Rows.Count; i++) { DataRow dr = dt1.Rows[i]; Console.WriteLine("{0}\t{1}\t{2}\t", dr[0], dr[1], dr[2]); }
完整的代码：
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using Newtonsoft.Json; namespace test01 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { DataTable dt = new DataTable(); DataColumn dcName = new DataColumn("Name"); DataColumn dcAge = new DataColumn("Age"); DataColumn dcCity = new DataColumn("City"); dt.Columns.Add(dcName); dt.Columns.Add(dcAge); dt.Columns.Add(dcCity); for (int i = 0; i < 10; i++) { DataRow dr = dt.NewRow(); dr[0] = "Name" + i; dr[1] = "Age" + i; dr[2] = "City" + i; dt.Rows.Add(dr); } string json = JsonConvert.SerializeObject(dt); this.richTextBox1.Text = json; } } }
Newtonsoft.Json 与 DataTable的相互转换
