asp.net通过流文件BinaryWrite的方式下载之后刷新当前页面

Response.Charset = "GB2312"; Response.AddHeader("Content-Disposition", "attachment; filename=\"" + HttpUtility.UrlEncode(PlanName, System.Text.Encoding.UTF8) + "\""); Response.AddHeader("Content-Length", byfs.Length.ToString()); Response.ContentEncoding = System.Text.Encoding.Default; Response.ContentType = "application/octet-stream"; Response.BinaryWrite(byfs); Response.Flush(); Response.Close();这是我的下载代码，能够实现下载，但是尝试了很多方法，不能实现下载后的刷新，求高手指点！

期待大神解決。00000
