我正在开发asp.net web项目.当我运行项目时,它正常工作.但在服务器中,我收到以下错误.如何解决这个问题呢？
Using themed css files requires a header control on the page. (e.g. `<head runat="server" />`).

如果页面不是为了呈现html,我觉得上面的答案都没有解决用户面临的实际问题.在这种情况下,解决方案是 - 只需粘贴以下内容即可
EnableTheming = "False" StylesheetTheme="" Theme=""
在该页面的@Page属性中.
例如,以下源代码示例:
DownloadFile.aspx.
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="DownloadFile.aspx.cs"
Inherits="WebUI.Monitorization.DownloadFile" EnableTheming="False" StylesheetTheme="" Theme="" %>

你需要在页面(或母版页)中使用runat ="server"的头标记,如下所示
<head runat="server">
<title></title>
</head>
