无法显示 XML 页

我用一个GridView的  HyperLinkField 项指定一个页面显示某个上传的文件(不同的人有不同的文件).
当此文件为.txt格式时能正常显示,当为.doc格式时就出现如下错误.为什么呢? (vs2005+asp.net+sql)

无法显示 XML 页。
使用样式表无法查看 XML 输入。请更正错误然后单击刷新按钮，或以后重试。

你是怎么样显示的啊……
代码呢？
是将文件读到网页中吗？

是啊,是将已经上传过的文件显示在网页中.我的代码是这样的.
  protected void Page_Load(object sender, EventArgs e)
{

      string ID = Request["ID"].ToString();
      Label1.Text = ID;
      Label1.Visible = false;

      SqlConnection meteor = new SqlConnection(System.Configuration.ConfigurationManager.AppSettings["meteor"]);
      meteor.Open();

      SqlCommand comm = new SqlCommand("select uploadfile from studentinformation where studentname ='" + Label1.Text.ToString().Trim() + "'", meteor);

      SqlDataReader dr = comm.ExecuteReader();

      string tmp;
      if (dr.Read())
      {
         tmp = dr["uploadfile"].ToString();
         if (tmp.Length > 0)
         {
            show();
         }
         else
         {
            Response.Write("<script language=javascript>alert('对不起,该生简历不存在!');window.close()</script>");
         }
      }

      meteor.Close();

}
private void show()
{
      SqlConnection meteor = new SqlConnection(System.Configuration.ConfigurationManager.AppSettings["meteor"]);
      meteor.Open();
      SqlCommand comm = new SqlCommand("select * from studentinformation where studentname ='" + Label1.Text.ToString().Trim() + "'", meteor);
      SqlDataReader dr = comm.ExecuteReader();
      if (dr.Read())
      {
         Label2.Text = dr.GetString(17);
         Label2.Visible = false;
      }
      meteor.Close();
      string strFileUploadPath = Server.MapPath("~/upload/");
      string strFileName = Label2.Text;
      string FullFileName = strFileUploadPath + strFileName;

      FileInfo DownloadFile = new FileInfo(FullFileName);
      Response.Clear();
      Response.ClearHeaders();
      Response.Buffer = false;
      Response.ContentType = "application/octet-stream ";
      Response.AppendHeader("Content-Disposition ", "attachment;filename= "
         + HttpUtility.UrlEncode(DownloadFile.FullName, System.Text.Encoding.UTF8));
      Response.AppendHeader("Content-Length ", DownloadFile.Length.ToString());
      Response.WriteFile(DownloadFile.FullName);
      Response.Flush();
      Response.End();

}
