我如何下载物理path中的空Excel文件？

在这里，我想下载链接中的空Excel文件button单击物理path中的事件。 我的代码是

HttpResponse httpResponse = HttpContext.Current.Response; httpResponse.Clear(); httpResponse.ClearContent(); httpResponse.ClearHeaders(); httpResponse.AddHeader("content-disposition", "attachment;filename=" + txt1.Text + ".xls"); string strpath = ConfigurationManager.AppSettings["Downloads"].ToString() + txt1.Text; httpResponse.ContentType = "application/vnd.ms-excel;"; StringWriter sw = new StringWriter(); HtmlTextWriter hw = new HtmlTextWriter(sw); string style = @"<style> .textmode { mso-number-format:\@; } </style>"; httpResponse.Write(style); httpResponse.Output.Write(sw.ToString()); httpResponse.Flush(); httpResponse.Close(); httpResponse.End(); 

我在Web.Config中的AddKey是

 <add key="Downloads" value="C:\Users\MyName\Desktop\Downloads"/> 

在这里，我怎么能给这个添加键值

也许这可以帮助你WebClient.DownloadFile

 using (var client = new WebClient()) { client.DownloadFile(theUrl, Path.Combine(ConfigurationManager.AppSettings["Downloads"].ToString(), "myXls.xls")); }
