使用c#读取excel中的数据

可以采用读取Access的方式读取excel中的数据

首先添加System.Data.OleDb引用

using System;using System.Collections.Generic;using System.Linq;using System.Text;using Word = Microsoft.Office.Interop.Word;using System.Data;using System.Data.Common;using System.Data.OleDb;namespace ConsoleApplication3{ class Program { static void Main(string[] args) { try { string file = @"E:\1.xls"; OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source="+ file +";Extended Properties=Excel 8.0"); conn.Open(); Console.WriteLine("连接成功"); OleDbCommand comm = new OleDbCommand("Select * from [Sheet1$] where [NO] is not null",conn); OleDbDataReader re = null; re = comm.ExecuteReader(); if (re != null) { string srt; while (re.Read()) { srt = re["修改日期"].ToString(); Console.WriteLine(srt); } } } catch (Exception ex) { Console.WriteLine(ex.Message); } } }}

我使用的office2007，excel的总列数是1048576，由于在建立Excel时候，执行了插入操作，会是Excel长度超过1048576

因此可以将上边的Select * from [Sheet1$] where [NO] is not null

改为：Select * from [Sheet1$A:B] where [NO] is not null

A：B表示读取两列

修改后读取的结果：
