用gridview顯示來自excel表格裡的數據

在asp.net 2.0中，如何用gridview顯示來自建立好的EXCEL檔案的內容呢，其實是很簡單的，下面給出簡單程式碼片斷

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$]";
OleDbCommand DBCommand = new OleDbCommand(SQLString, DBConnection);
IDataReader DBReader = DBCommand.ExecuteReader();
GridView1.DataSource = DBReader;
GridView1.DataBind();
DBReader.Close();
DBConnection.Close();
}
其中，把demo1.xls放在app_data目錄下，這裡用select * from [Sheet1$]來取出sheet1的內容。
