Re: [問題]C# 讀寫excel file
我只會讀的部份,就參考一下唄~~
其他請各位高手指導一下，謝謝！
using System.Data.SqlClient;
using System.Data.OleDb;
private void btnLoad_Click(object sender, EventArgs e)
{
string cnStr = "Data Source=C:\\Database\\employee.xls;Provider=Microsoft.Jet.OLEDB.4.0;Extended Properties=Excel 8.0;";
using (OleDbConnection cn = new OleDbConnection(cnStr))
{
using (OleDbCommand cmd = new OleDbCommand())
{
cmd.Connection = cn;
cn.Open();
cmd.CommandText = "SELECT * from [data$]"; //sheet name
using (OleDbDataReader dr = cmd.ExecuteReader())
{
while (dr.Read())
{
ListBox1.Items.Add(dr[0].ToString() + "\t" + dr[1].ToString() + "\t" + dr[2].ToString());
}
}
}
}
}

: 連線方式可以去connectionstring網站找
