用gridview显示来自excel表格里的数据

在asp.net 2.0中，如何用gridview显示来自建立好的EXCEL文件的内容呢，其实是很简单的，下面给出简单代码片断

protected void Page_Load(object sender, EventArgs e)
{
OleDbConnection DBConnection = new
OleDbConnection(“Provider=Microsoft.Jet.OLEDB.4.0;” + “Data Source=” +
Server.MapPath(“~/App_Data/demo1.xls”) + “;” + “Extended
Properties=\\”Excel 8.0;HDR=Yes\\”");
DBConnection.Open();
string SQLString = “SELECT * FROM [Sheet1]“;
OleDbCommand DBCommand = new OleDbCommand(SQLString, DBConnection);
IDataReader DBReader = DBCommand.ExecuteReader();
GridView1.DataSource = DBReader;
GridView1.DataBind();
DBReader.Close();
DBConnection.Close();
}
其中，把demo1.xls放在app_data目录下，这里用select * from [Sheet1]来将sheet1的内容取出来。
