C# ASP使用TransmitFile（）下载文件

我正在使用Response.TransmitFile（）从C驱动器上的文件夹下载zip文件夹。文件夹下载很好，我得到的文件出现在我的下载文件夹。然而，问题是在我的下载文件夹中，有一个名为asp页面的zip文件，里面是我想要下载的文件夹。另一个问题是我在上传的zip文件夹的末尾附加了一个DataTime，但是日期也不在文件夹名称的末尾

我的上传代码如下所示：

string pnq = HttpContext.Current.Request.Url.PathAndQuery;
string url = HttpContext.Current.Request.Url.AbsoluteUri.Replace(pnq, "/");
if (FileUpload1.HasFile)
{
        var filename = FileUpload1.PostedFile.FileName;
        var uriID = Guid.NewGuid().ToString();
        var password = System.Web.Security.Membership.GeneratePassword(7, 2);
        filename = filename.Remove(filename.Count() - 4) + "-" + DateTime.Now.ToShortDateString() + ".zip";
        filename = filename.Replace(" ", "-");
        filename = filename.Replace("/", "-");
        FileUpload1.SaveAs("C:\\Uploads\\" + filename);
        lblUri.Text = url + "UICDownload.aspx?fileID=" + uriID;
        lblPassword.Text = password;
        string file = MapPath("~/Sample.xml");
        XDocument doc = XDocument.Load(file);
        doc.Root.Add(new XElement("File", new XElement("name", filename), new XElement("uriID", uriID), new XElement("password", password)));
        XElement name = new XElement("name", filename);
        doc.Save(file);
}

    var text = Request.QueryString["fileID"];
    string file = MapPath("~/Sample.xml");
    XDocument doc = XDocument.Load(file);
    var node = doc.Document.Descendants("uriID").FirstOrDefault(u => u.Value.Equals(text));
    var filenode = node.Ancestors("File").First();
    var tempname = filenode.Element("name");
    var filename = tempname.Value.ToString();
    var filePassword = filenode.Element("password");
    if (filePassword.Value.ToString() == tbPassword.Text)
    {
        Response.Clear();
        Response.ContentType = "application/zip";
        Response.AppendHeader("Content-Disposition", "attachment; fileID=" + text);
        Response.TransmitFile("C:\\Uploads\\" + filename);
        Response.End();
    }

欢迎提供任何建议，如果您想让我显示任何其他代码，请告诉我。另外，当文件上载到C:\Uploads文件夹时，zip文件夹的名称末尾有日期。

请尝试将此行更改为以下内容：

Response.AppendHeader("content-disposition", "attachment; filename=" + filename);

至于zip文件的嵌套，如果你压缩一个文件夹，它就会创建嵌套在你的zip文件中的文件夹。当你创建zip时，只需压缩文件（希望有意义？）至于zip文件的嵌套，如果你压缩一个文件夹，它就会创建嵌套在你的zip文件中的文件夹。当你创建zip时，只需压缩文件（希望这有意义？）
