推荐答案
在您查看输出，你可以只添加一个 jQuery的客户端脚本来做到这一点，这将运行一次你的网页是拼凑起来的：
In your view output you could just add a jQuery client script to do it which will run once your page is pieced together:
$('body').addClass('yourClass');
另一种方法是将类数据存储在控制器中，如：
Another method would be to store the class data in your controller like:
ViewData["MasterPageBodyClass"] = "yourClass";
然后在你的母版查看您可以检查这是否存在等，并添加它，如果它存在：
Then in your MasterPage view you could check for the existance of this and add it if it exists:
<%
string bodyClass = "";
if (ViewData["MasterPageBodyClass"] != null)
{
bodyClass = "class=\"" + ViewData["MasterPageBodyClass"].ToString() + "\"";
}
%>
<body <%= bodyClass %>>
只有所需的类被连接到主体实际上需要将类存储在的ViewData 每隔一个行动可以忽略它的控制器的动作。
Only the controller actions that required the class to be attached to the body would actually need to store the class in the ViewData every other action could just ignore it.
