Response.Clear();
Response.Buffer= true;
Response.Charset="utf-8";

//下面这行很重要， attachment 参数表示作为附件下载，您可以改成 online在线打开

//filename=FileFlow.xls 指定输出文件的名称，注意其扩展名和指定文件类型相符，可以为：.doc || .xls || .txt ||.htm

Response.AppendHeader("Content-Disposition","attachment;filename=FileFlow.xls");
Response.ContentEncoding=System.Text.Encoding.GetEncoding("utf-8");

//Response.ContentType指定文件类型可以为application/ms-excel || application/ms-word || application/ms-txt || application/ms-html || 或其他浏览器可直接支持文档

Response.ContentType = "application/ms-excel";
this.EnableViewState = false;

　　二、定义一个输入流

System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);

　　三、将目标数据绑定到输入流输出

this.RenderControl(oHtmlTextWriter);

//this 表示输出本页，你也可以绑定datagrid,或其他支持obj.RenderControl()属性的控件

Response.Write(oStringWriter.ToString());
Response.End();
