本文介绍了一种使用ASP.NET将GridView数据导出为Excel文件的方法。通过设置HTTP响应头和编码方式，确保了导出文件能被正确解析。文中还提供了一个用于避免错误的辅助方法。

///

/// 导出Excel ///

/// /// protected void btnExcel_Click(object sender, EventArgs e) { Response.Clear(); System.Web.HttpContext curContext = System.Web.HttpContext.Current; Response.AddHeader("content-disposition", "attachment;filename=instimestock.xls"); Response.Charset = "utf-8"; Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312"); Response.ContentType = "application/vnd.xls"; System.IO.StringWriter stringWrite = new System.IO.StringWriter(); System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite); //写到Excel的数据不用分页 //BindData(); [color=#FF0000]gridviewName[/color].RenderControl(htmlWrite); Response.Write(stringWrite.ToString());//向客户端写数据 Response.End(); } //这个方法不写的话可能报错类型“GridView”的控件“GridView1”必须放在具有 runat=server 的窗体标记内。 public override void VerifyRenderingInServerForm(Control control) { // Confirms that an HtmlForm control is rendered for }
