下面是一个将DataGrid中的数据生成Excel文档的方法,其中System.Web.UI.Control ctl指DataGrid的ID,
FileName指要生成Excel文件的名称。
//生成Excel文件 public void ToExcel(System.Web.UI.Control ctl, string FileName) { //设置网络输出流的HTTP字符集为UTF-8,Current为当前 HTTP 请求获取 HttpContext 对象 HttpContext.Current.Response.Charset = "GB2312"; HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.Default; //设置输出流HTTPMIME类型为excel HttpContext.Current.Response.ContentType = "application/ms-excel"; //将HTTP头添加到输出流 HttpContext.Current.Response.AppendHeader("Content-Disposition","attachment;filename="+""+ FileName+".xls"); //不保存该控件的视图状态 ctl.Page.EnableViewState = false; System.IO.StringWriter sw = new System.IO.StringWriter(); //将文本写入到输出流 System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(sw); //将服务器控件的内容输出到HtmlTextWriter对象中 ctl.RenderControl(hw); //StringWriter.ToString返回包含迄今为止写入到当前 StringWriter 中的字符的字符串 HttpContext.Current.Response.Write(sw.ToString()); HttpContext.Current.Response.End(); }
