传值id到一个页面，在该页面写路径下载，就可以了少了一句：FileInfo file = new FileInfo(Server.MapPath("..//reports//erp.zip"));//路径Response.ContentEncoding = System.Text.Encoding.GetEncoding("UTF-8"); //解决中文乱码
            Response.AddHeader("Content-Disposition", "attachment; filename=" + Server.UrlEncode(file.Name)); //解决中文文件名乱码    
            Response.AddHeader("Content-length", file.Length.ToString());
            Response.ContentType = "application/pdf";
            Response.WriteFile(file.FullName);
            Response.End();
