"Do you want to Open or save"不显示

Question

我的代码：

    [AcceptVerbs(HttpVerbs.Get)]
    public ActionResult Export()
    {
        DataTable table = ListToDataTable();
        var rows = table.AsEnumerable().AsQueryable() as IEnumerable<DataRow>;
        var output = CreateXlsStream(rows);
        return File(output, "application/vnd.ms-excel", "Export.xls");
    }

"您要打开还是保存"不显示。我想在执行此"返回文件（输出，" application/vnd.ms-excel"，" export.xls"）;'之后默认显示"您要打开或保存"。line.thanks。

这应该有效：

Response.AppendHeader("Content-Disposition", "inline; filename=Export.xls");
return File(...
