本文介绍了一种将ASP.NET中的GridView控件数据导出为Excel文件的方法。通过设置HTTP响应头并利用HtmlTextWriter渲染控件内容，实现快速导出功能。

    /// <summary>
    /// 将GridView导出到Excell
    /// </summary>
    /// <param name="gv">GridView标识</param>
    /// <param name="fileName">保存的文件名</param>
    void ExportToExcell(GridView gv,string fileName)
    {
        Response.Clear();
        Response.Buffer = true;
        Response.Charset = "GB2312";
        Response.AppendHeader("Content-Disposition", "attachment;filename=" + fileName + ".xls");
        Response.ContentEncoding = System.Text.Encoding.UTF7;
        Response.ContentType = "application/ms-excel";
        System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
        System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
        gv.RenderControl(oHtmlTextWriter);
        Response.Output.Write(oStringWriter.ToString());
        Response.Flush();
        Response.End();
