    {

        Response.Redirect("Default2.aspx?filename=Csharp/CSharp.txt");              
    }

Download.aspx 下载.aspx

 protected void Page_Load(object sender, EventArgs e) <br/>

    {
        string filename = Request.QueryString["filename"];
        Response.ContentType = "text";
        Response.AppendHeader("Content-Disposition", "attachment; filename=CSharp.txt");

Use additional flag to indicate that the the actual downloading should be made. 使用附加标志指示应进行实际下载。 In a meantime you can show a "Please wait" message. 在此期间，您可以显示“请稍候”消息。 Like this: 像这样：

<!DOCTYPE html>
<html>
  <head>
    <meta http-equiv="refresh" content="3; url=<%=HttpUtility.HtmlAttributeEncode(Request.Url.OriginalString + &IsDownloading=true")%>">
  </head>

  <body>
    <h2>Your download will start shortly...</h2>
  </body>
</html>

Code-behind: 后台代码：

protected void Page_Load(object sender, EventArgs e)
{
    if(string.Compare((Request.QueryString["IsDownloading"] ?? string.Empty).Split(new char[] { ',' }).First(), "true", StringComparison.InvariantCultureIgnoreCase) == 0)
  {
    // Make a file transfer
  }
}
