阅读excel

string con = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=E:\YEVMIYE.xls;Extended Properties='Excel 8.0;HDR=Yes;'";
        using (OleDbConnection connection = new OleDbConnection(con))
        {
            connection.Open();
            //OleDbCommand command = new OleDbCommand("select * from [RAPOR01$]", connection);
            OleDbCommand command = new OleDbCommand("select [B], [C], [D], [E], [F] from [RAPOR01$]", connection);
            using(OleDbDataReader dr = command.ExecuteReader())
            {
                while (dr.Read())
                {
                    var row1Col1 = dr[0];
                    var row1Col2 = dr[1];
                    var row1Col3 = dr[2];
                    var row1Col4 = dr[3];
                    var row1Col5 = dr[4];

                    listBox1.Items.Add(row1Col1);
                    listBox2.Items.Add(row1Col2);
                    listBox3.Items.Add(row1Col3);
                    listBox4.Items.Add(row1Col4);
                    listBox5.Items.Add(row1Col5);
                }
                listBox1.SelectedIndex = 0;
            }
        }

[B]，[C]，[D]，[E]都可以。但最后一栏变空了。

尝试将IMEX=1添加到您的连接字符串中：

string con = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Users\peterb\Downloads\YEVMIYE.xls;Extended Properties='Excel 8.0;HDR=Yes;IMEX=1;'";
