下載文檔時Safari瀏覽器下載后出現".html"問題

下載代碼是需要設置 Response.ContentType = "application/octet-stream",

不要設為application/x-msdownload，改設為applicatoin/octet-stream即可（這種格式代表任意的二進制數據）,

ContentType用於定義用戶的瀏覽器或相關設備如何顯示將要加載的數據。

 代碼如下：

        private static void RenderToBrowser(byte[] bytes, HttpContext context, string downloadname)
        {
            if (context.Request.Browser.Browser == "IE")
            {
                downloadname = HttpUtility.UrlEncode(downloadname, System.Text.Encoding.UTF8).Replace("+", "%20");
            }
            context.Response.ContentType = "application/octet-stream";
            context.Response.AddHeader("Content-Disposition", "attachment;fileName=" + downloadname);
            context.Response.BinaryWrite(bytes);
            context.Response.Flush();
            context.Response.End();
        }
