ASP.NET中操作Word和Excel(二)

使用HttpContext对象，导出到word。这个比较通用，也可以导出到excel等。可将整个页面(Page)，或者DataGrid，DataList等控件使用RenderControl()方法到word，提示用户选择下载存放地址。


HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment;filename=" + filename);


HttpContext.Current.Response.Charset = "UTF-8";


HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.Default;


HttpContext.Current.Response.ContentType = filetype;


//HttpContext.Current.Response.ContentType = "application/ms-excel";//image/JPEG;text/HTML;image/GIF;vnd.ms-excel/msword


System.IO.StringWriter tw = new System.IO.StringWriter();


System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(tw);


gv.RenderControl(hw);


HttpContext.Current.Response.Write(tw.ToString());


HttpContext.Current.Response.End();
