奶雞的隨筆寫寫

使用WEB FORM 下載EXCEL 當然如果ContentType改變就可以下載其他檔案格式 
甚至可以使用 application/octet-stream 處理大部分的'格式 (聽說有安全性或效能問題?)

 private void ResponseWriteExcel(string OutFileName, byte[] buffer)
    {
        HttpContext.Current.Response.Clear();
        HttpContext.Current.Response.Buffer = true;
        HttpContext.Current.Response.Charset = "";
        HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
        HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.UTF8;
        HttpContext.Current.Response.ContentType = "application/vnd.ms-excel";
        HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment;filename=" + OutFileName + ";");
        HttpContext.Current.Response.BinaryWrite(buffer);
        HttpContext.Current.Response.Flush();
        HttpContext.Current.Response.End();
    }
