Question

我目前正在尝试创建一个按钮，可以将文本文件从我的网站下载到用户计算机。我有正确的文件上传到网站，但下载它的代码不起作用。这就是我所拥有的：

private ActionResult CallProgram(string path) //calls program that outputs txt file to website
    {
       using (Process exeProcess = Process.Start(startInfo)) //program called
        { 
           lines = exeProcess.StandardOutput.ReadToEnd();
           Information info = new Information();

           //save txt to website
           info.fileName = Path.GetFileName(path);
           info.filePath = Path.Combine(Server.MapPath("~/App_Data/uploads"), info.fileName + "_results.txt");

           using (StreamWriter outfile = new StreamWriter(info.filePath))
            {
              outfile.Write(lines);
              outfile.Close();
            } //text output saved to txt
         }

        return RedirectToAction("results_download", new { output = info });
     }

以下是行动：

public ActionResult results_download(Information output)
    {
        return View(output);
    }

aspx文件中按钮的实际代码：

<script runat="server">
protected System.IO.File download_BTN_Click(object sender, EventArgs e)
{
    Response.Clear();
    Response.ContentType = "text/plain";
    Response.AppendHeader("Content-Disposition", "attachment; filename=Model.fileName");
    Response.TransmitFile(Server.MapPath("~/App_Data/uploads/"+info.fileName)); //
    Response.End();
}

<div>
    <asp:Button ID="download_BTN" runat="server" OnClick="download_BTN_Click" fileName="" Text="Download Results" />
</div>

我是asp.net的新手，并且给了一个远远超出我能力的项目。所以我可能只是犯了一个愚蠢的错误。谢谢。
