Question

我正在尝试下载一个zip文件，并以相同的方式提取并运行未压缩的内容，但是当执行代码时，zip文件正在服务器位置提取，并且内容也在该位置运行。下面是我编写的代码。我已经在本地网络上托管了代码。我什至尝试了Write（）而不是TransmitFile（）

try
{
    string launchPresentationPath = Convert.ToString(e.CommandArgument);
    string exeFolder = launchPresentationPath.Replace("/Launch_Presentation.exe", "");

    string path = HttpContext.Current.Request.PhysicalApplicationPath + "/Uploads/" + exeFolder + ".zip"; //+ Convert.ToString(e.CommandArgument);

    string userRoot = System.Environment.GetEnvironmentVariable("USERPROFILE");
    string str1 = Environment.GetFolderPath(Environment.SpecialFolder.UserProfile);

    downloadFolder = Path.Combine(userRoot, "Downloads");

    string strAttach = "attachment; filename=" + exeFolder.Substring(exeFolder.IndexOf('/') + 1) + ".zip";

    System.IO.FileInfo file = new System.IO.FileInfo(path);
    if (file.Exists)
    {
        HttpResponse res = HttpContext.Current.Response;
        res.Clear();
        res.AppendHeader("content-disposition", strAttach);
        res.ContentType = "application/octet-stream";
        res.TransmitFile(path);

        using (ZipFile zip2 = ZipFile.Read(path))
        {
            zip2.ExtractAll(downloadFolder, Ionic.Zip.ExtractExistingFileAction.DoNotOverwrite);
        }

        DirectoryInfo f = new DirectoryInfo(downloadFolder + "\\" + exeFolder.Substring(exeFolder.IndexOf('/') + 1));
        FileInfo[] a = f.GetFiles();
        if (a.Length > 0)
        {
            ProcessStartInfo myProcess = new ProcessStartInfo(downloadFolder + "\\" + exeFolder.Substring(exeFolder.IndexOf('/') + 1) + "\\Launch_Presentation.exe");

            myProcess.UseShellExecute = false;

            Process process = Process.Start(myProcess);
            int Exeid = process.Id;

            this.Visible = false;
            this.Visible = true;
            process.EnableRaisingEvents = true;
            pdfFrame.Visible = videoFrame.Visible = false;
            Response.Redirect(Convert.ToString(this.Page.Request.Url.AbsoluteUri));
            process.Exited += (myProcess_HasExited);
        }

        res.Flush();
        res.End();
    }

}
catch (Exception ex)
{

}

为什么它不在客户端位置下载？

可能是与定义为downloadFolder的客户端路径的许可有关的问题。请检查并通知我。

无法在客户端位置C＃Asp.NET上下载文件
