喜试试下面code段

Hi try below code snippet

    using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data;

命名空间ConsoleApplication1{    类节目    {        公共静态数据表GetDataTable（）        {            //创建一个新的DataTable对象            数据表objDataTable =新的DataTable（）;            //创建一个字符串三列它们的类型            objDataTable.Columns.Add（列1中的typeof（字符串））;            objDataTable.Columns.Add（列2中的typeof（字符串））;            objDataTable.Columns.Add（列3中的typeof（字符串））;            //添加一些数据在此数据表中的行            objDataTable.Rows.Add（新的String [] {ROW1 - 列1，ROW1 - 列2，ROW1 - Column3}）;            objDataTable.Rows.Add（新的String [] {的Row2 - 列1，的Row2 - 列2，的Row2 - Column3}）;            objDataTable.Rows.Add（新的String [] {ROW3 - 列1，ROW3 - 列2，ROW3 - Column3}）;            回报objDataTable;

namespace ConsoleApplication1{ class Program { public static DataTable GetDataTable() { //Create a new DataTable object DataTable objDataTable = new DataTable(); //Create three columns with string as their type objDataTable.Columns.Add("Column 1", typeof(string)); objDataTable.Columns.Add("Column 2", typeof(string)); objDataTable.Columns.Add("Column 3", typeof(string)); //Adding some data in the rows of this DataTable objDataTable.Rows.Add(new string[] { "Row1 - Column1", "Row1 - Column2", "Row1 - Column3" }); objDataTable.Rows.Add(new string[] { "Row2 - Column1", "Row2 - Column2", "Row2 - Column3" }); objDataTable.Rows.Add(new string[] { "Row3 - Column1", "Row3 - Column2", "Row3 - Column3" }); return objDataTable;

}
