资源解释为其他但传输的MIME类型未定义.IE的错误(Asp.net网站)

Question

当我尝试从Chrome下载它工作正常,但在IE 8中它没有下载它显示上面的错误,

    protected void btn_ExcelDownload_Click(object sender, EventArgs e)
{
    Grid_UserTable.Columns[0].Visible = false;
    string subject = lbl_Subj.Text;
    Response.Buffer = true;
    Response.Clear();
    Response.ClearHeaders();
    Response.AddHeader("Cache-Control", "no-store, no-cache");
    Response.AddHeader("content-disposition", "attachment;filename=" + subject + "-Status.xls");
    Response.Charset = "";
    Response.Cache.SetCacheability(HttpCacheability.NoCache);
    Response.ContentType = "application/vnd.ms-excel";
    System.IO.StringWriter stringWrite = new System.IO.StringWriter();
    System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
    Grid_UserTable.RenderControl(htmlWrite);
    rptList.RenderControl(htmlWrite);
    Response.Write(stringWrite.ToString());     
    Response.End();
}

当我在chrome中使用开发人员工具时,它将Resource解释为Other,但是使用MIME类型undefined进行传输.错误,但下载了文件,但IE正在抛出图像中显示的错误,我该怎么办,谢谢.

当我使用Visual Studio运行网站时,我能够在IE8中下载该文件,但是当我尝试从上传到服务器的网站下载时,我收到上述错误,错误仅在IE 8中.

我尝试打开和关闭IE浏览器兼容模式,即使这样我也收到同样的错误.

这是我的头脑内容

<asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="Server">
    <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE8" />

Answer 1

  Response.Cache.SetCacheability(HttpCacheability.NoCache);

通过从代码中删除这一行来解决。
