jquery - 通过 HttpHandler 下载多文件

Question

在我的应用程序中，用户可以下载自己的文件（图像、pdf、word、...）。我使用 HttpHandel 来做。开始选择文件并下载。我希望用户可以从列表中下载所有文件。怎么做？

 public void ProcessRequest(HttpContext context) {

        HttpResponse response = context.Response;
        string cururl = context.Request.Url.ToString();
        int iqs = context.Request.Url.ToString().IndexOf('?');
        string querystring = (iqs < cururl.Length - 1) ? cururl.Substring(iqs + 1) : String.Empty;
        NameValueCollection parameters = HttpUtility.ParseQueryString(querystring);
        byte[] result = GetstreamForDownload(parameters);
        string fileId = context.Request.QueryString["fileId"];
        response.AddHeader("Content-disposition", "attachment; filename=" + GetFileName(parameters));
        response.ContentType = "application/octet-stream";
        response.BinaryWrite(result);

}
