C# 读取excel组件方法?

Posted 2023-03-29

这是我以前写的winform 把Excel 数据导入到Access 表中 下面的后台代码
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Data.OleDb;
//Download by http://www.codefans.net
namespace ParkLottery

public partial class ImportPerson : Form

public ImportPerson()

InitializeComponent();


private void button1_Click(object sender, EventArgs e)

SaveFileDialog dlg = new SaveFileDialog();
dlg.Filter = "Excel文件(*.xls)|*.xls";
if (dlg.ShowDialog() == DialogResult.OK)

string filePath = dlg.FileName;
this.textBox1.Text = filePath;




private void button2_Click(object sender, EventArgs e)

if (textBox1.Text.Length == 0)

MessageBox.Show("请选择导入数据的Execl文件");

else

try


OleDbConnectionStringBuilder connectStringBuilder = new OleDbConnectionStringBuilder();
connectStringBuilder.DataSource = this.textBox1.Text.Trim();
connectStringBuilder.Provider = "Microsoft.Jet.OLEDB.4.0";
connectStringBuilder.Add("Extended Properties", "Excel 8.0");
using (OleDbConnection cn = new OleDbConnection(connectStringBuilder.ConnectionString))

DataSet ds = new DataSet();
string sql = "Select * from [Sheet1$]";
OleDbCommand cmdLiming = new OleDbCommand(sql, cn);
cn.Open();
using (OleDbDataReader drLiming = cmdLiming.ExecuteReader())

ds.Load(drLiming, LoadOption.OverwriteChanges, new string[] "Sheet1" );
DataTable dt = ds.Tables["Sheet1"];
if (dt.Rows.Count > 0)

for (int i = 0; i < dt.Rows.Count; i++)


//写入数据库数据
string MySql = "insert into ClientInfo values('"+dt.Rows[i]["姓名"].ToString()+"','"+dt.Rows[i]["姓名"].ToString()+"','0','"+dt.Rows[i]["备注"].ToString()+"','0','"+i.ToString()+"')";
new DataAccess().SQLExecute(MySql); //执行sql语句插入到access数据库中

MessageBox.Show("数据导入成功！");

else

MessageBox.Show("请检查你的Excel中是否存在数据");




catch (Exception ex)

MessageBox.Show(ex.ToString());




追问

我想请问一下有没有快速读取excel数据到数据库的方法 类似于批量导入 非常感谢
