今天看到Json转DataTable的例子,总结一下.... using System; using System.Collections; using System.Collections.Generic; using System.Data; using System.IO; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Web; using System.Web.Script…

在json转换成对象时,json的key会与java 类的字段一一对应.如果没有映射上的java字段会在该数据类型上填充默认值,如int 0,String null 等. 没有映射的json key在程序结束后会用警告显示出来,告知程序员那个key值没有被映射上 import net.sf.json.JSONObject; public class MainClass { public static void main(String[] args) { TestJsonBean(); } /**…

步骤: 一.前台JS取HtmlTable数据,根据设定的分隔符把数据拼接起来 <!--导出Excel--> <script type="text/javascript"> //导出Excel function exportExcel() { var data = ""; $("#divRptTable").find("table").find("tr").each(function…

list转换成DataTable类如下: public static DataTable ToDataTable<T>(this IList<T> datas) { DataTable dt = new DataTable(); Type type = typeof(T); PropertyInfo[] properties = type.GetProperties(); List<KeyValuePair<PropertyInfo, ExportFieldAttrib…

领导让在存储过程中批量添加数据,找出效率最高的,我看到后台代码后,发现可以将list<对象>转换成DataTable,把DataTable转换成参数传入存储过程实现批量插入数据,知道还有其他的方法,不过这个方法已经实现,就写一下了: 1.创建表. CREATE TABLE [dbo].[person]( [ID] [,) NOT NULL, [Name] [nvarchar]() NULL, [Pwd] [nvarchar]() NULL, [Age] [int] NULL ) 2.创建表值参…
