ASP.NET：如何把Gridview中的数据导出到EXCEL表格（使用默认格式）

我导出的EXCEL文件都是带边框的，我现在只想导出为无任何格式的EXCEL文件，该如何实现啊？
参考代码：
protected void Button1_Click(object sender, EventArgs e)
{
System.Web.UI.Control ctl = this.GridView1;
HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment;filename=Excel.xls");
HttpContext.Current.Response.Charset = "UTF-8";
HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.Default;
HttpContext.Current.Response.ContentType = "application/ms-excel";
ctl.Page.EnableViewState = false;
System.IO.StringWriter tw = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(tw);
ctl.RenderControl(hw);
HttpContext.Current.Response.Write(tw.ToString());
HttpContext.Current.Response.End();
}
public override void VerifyRenderingInServerForm(Control control)
{
// Confirms that an HtmlForm control is rendered for
}
现在我知道他导出的是HTML格式的（用记事本可以打开），所以才会带边框，现在我想要的是导出EXCEL的标准格式（也就是用记事本打开是乱码的那种）

Answer 1

System.Web.UI.Control ctl=this.DataGrid1;
//DataGrid1是你在窗体中拖放的控件
HttpContext.Current.Response.AppendHeader("Content-Disposition","attachment;filename=Excel.xls");
HttpContext.Current.Response.Charset ="UTF-8";
HttpContext.Current.Response.ContentEncoding =System.Text.Encoding.Default;
HttpContext.Current.Response.ContentType ="application/ms-excel";
ctl.Page.EnableViewState =false;
System.IO.StringWriter tw = new System.IO.StringWriter() ;
System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter (tw);
ctl.RenderControl(hw);
HttpContext.Current.Response.Write(tw.ToString());
HttpContext.Current.Response.End();
