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。
