如何将元标记添加到asp.net中的内容占位符页面？
我想在IE 11浏览器中渲染时强制IE模式为7。能够通过在head标签下放置一个单独的aspx页面来实现。但我想为单个内容占位符页面这样做。
< pre lang =HTML>& lt; meta http-equiv =& ;英寸×UA兼容&安培; QUOT;含量=&安培; QUOT; IE = 7和; QUOT; /& gt;< / pre>

How to add meta tag to a content place holder page in asp.net?
I want to force IE mode to 7 while rendering in IE 11 browser. Able to do so by putting under the head tag for a separate aspx page. But I want to do so for a single content place holder page.
<pre lang="HTML"><meta http-equiv="X-UA-Compatible" content="IE=7" /></pre>

推荐答案
如果要从内容页面向页眉添加自定义标签，只需添加另一个ContentPlaceholder位置正确：
母版页：
If you want to add custom tags to the page header from a content page, you just need to add anotherContentPlaceholderin the correct position:
Master page:
<%@ Master Language="C#" %>
<!doctype html>
<html>
<head runat="server">
...
<asp:ContentPlaceholder id="HeaderContent" runat="server" />
...
</head>
<body>
...
<asp:ContentPlaceholder id="MainContent" runat="server" />
...
</body>
</html>
内容页面：
Content page:
<%@ Page Language="C#" MasterPageFile="~/YourMasterPage.master" %>
<asp:Content runat="server" ContentPlaceholderID="HeaderContent">
Extra headers here...
</asp:Content>
<asp:Content runat="server" ContentPlaceholderID="MainContent">
Page content here...
</asp:Content>
然而，在这种情况下没有必要这样做。任何< meta http-equiv ... 标记都是响应标头的替代。您真正需要做的就是从内容页面的代码隐藏中添加标题：
However, there's no need to do that in this case. Any <meta http-equiv... tag is a substitute for a response header. All you really need to do is add the header from the code-behind of your content page:
public partial class YourPage : Page
{
public void Page_Load(object sender, EventArgs e)
{
Response.AppendHeader("X-UA-Compatible", "IE=7");
}
}
