Dataset ds = new DataSet();
string ConnStr = "Provider=Microsoft.Jet.OleDb.4.0;data source=" + filepath +
";Extended Properties='Excel 8.0; HDR=YES; IMEX=1'";//连接Excel的字符串
string query = "SELECT * FROM [student$]";//Excel中的表名称
OleDbCommand oleCommand = new OleDbCommand(query, new OleDbConnection(ConnStr));
OleDbDataAdapter oleAdapter = new OleDbDataAdapter(oleCommand);
oleAdapter.Fill(ds, "[student$]");
rowcount = ds.Tables[0].Rows.Count;
gridview1.DataSource = ds;
gridview1.DataBind();
lblmes.Text = "上传成功，数据如下所示，请确认：";//lblmes为label，显示提示信息
}
