下载文件，停在Responce.end()

Question

我有一个代码，可以将文件压缩到文件夹中并下载 zip 文件 但下载后代码停在response.end()处 之后我有代码删除了文件夹中的所有文件，但它永远不会去那里。

有人知道为什么吗？

这是代码

protected void download_Click1(object sender, ImageClickEventArgs e)

{

string dirRoot = "E:\洗衣机\"; string[] filesToZip = Directory.GetFiles(dirRoot, "*.csv", SearchOption.AllDirectories); string zipFileName = string.Format("cleaned-{0:yyyy-MM-dd}.zip", DateTime.Now);

using (MemoryStream zipMS = new MemoryStream())
{
    using (ZipArchive zipArchive = new ZipArchive(zipMS, ZipArchiveMode.Create, true))
    {
        foreach (string fileToZip in filesToZip)
        {
            if (new FileInfo(fileToZip).Extension == ".zip") continue;
            if (fileToZip.Contains("node_modules")) continue;
            byte[] fileToZipBytes = System.IO.File.ReadAllBytes(fileToZip);
            ZipArchiveEntry zipFileEntry = zipArchive.CreateEntry(fileToZip.Replace(dirRoot, "").Replace('\\', '/'));
            using (Stream zipEntryStream = zipFileEntry.Open())
            using (BinaryWriter zipFileBinary = new BinaryWriter(zipEntryStream))
            {
                zipFileBinary.Write(fileToZipBytes);
            }

            //lstLog.Items.Add("zipped: " + fileToZip);
        }
    }

    using (FileStream finalZipFileStream = new FileStream("E:\\WashingMachine\\" + zipFileName, FileMode.Create))
    {
        zipMS.Seek(0, SeekOrigin.Begin);
        zipMS.CopyTo(finalZipFileStream);
    }
    string filePath = "E:\\WashingMachine\\" + zipFileName +" ";
    FileInfo file = new FileInfo(filePath);
    if (file.Exists)
    {
        Response.Clear();
        Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name);
        Response.AddHeader("Content-Length", file.Length.ToString());
        Response.ContentType = "text/plain";
        Response.Flush();
        Response.TransmitFile(file.FullName);
        Response.End();
    }

}

string[] directoryFiles = System.IO.Directory.GetFiles(dirRoot, "*.*");
foreach (string directoryFile in directoryFiles)
{
    System.IO.File.Delete(directoryFile);
}
//lstLog.Items.Add("ZIP Archive Created.");

}

我已经改成这个了，现在可以用了

               string filePath = "E:\\WashingMachine\\" + zipFileName + " ";
           FileInfo file = new FileInfo(filePath);
           string Outgoingfile = zipFileName;
           if (file.Exists)
           {
               Response.Clear();
               Response.ClearContent();
               Response.ClearHeaders();
               Response.AddHeader("Content-Disposition", "attachment; filename=" + Outgoingfile);
               Response.AddHeader("Content-Length", file.Length.ToString());
               Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
               Response.WriteFile(file.FullName);
               Response.Flush();
               Response.Close();
           }
