怎样把数据导出成word文档或者Excel

在网上找的，直接上代码：把控件名称传入方法即可，强制转换一下。(Control) 控件名
public static void OutPutExcel(Control con)
        {
            HttpResponse Response = HttpContext.Current.Response;
            //定义文档类型、字符编码
            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 = Encoding.UTF8;;//GB2312             //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";
            //DG.EnableViewState = false;
            //　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);

            con.RenderControl(oHtmlTextWriter);
            //System.IO.Directory.CreateDirectory(HttpContext.Current.Server.MapPath("/") + "excel/" + DateTime.Now.ToString("yyyyMMdd") + "/");
            //string s = HttpContext.Current.Server.MapPath("/") + "excel/" + DateTime.Now.ToString("yyyyMMdd") + "/" + DateTime.Now.ToString("yyyyMMddHHmmsss")+".aspx";
            //System.IO.File.WriteAllText(s, oStringWriter.ToString());
            //ScriptManager.RegisterClientScriptBlock(con, con.GetType(), "excel", "open('/excel/" + DateTime.Now.ToString("yyyyMMdd") + "/" + DateTime.Now.ToString("yyyyMMddHHmmsss") + ".aspx" + "');", true);
            Response.Write(oStringWriter.ToString());
            
            Response.End();
        }
