动态更改CSS [英] Change CSS Dynamically

问题描述

我需要确定哪些 CSS 应用于某些特定网页。我有一个母版页，其中包含子级， default.aspx 和 services.aspx 是母版页的子级。我想要的是当用户导航 Default.aspx 或 Services.aspx 时，系统应该应用 DefaultCSS 文件，否则我想应用一些普通css 文件。

I need to determine which CSS should be applied on some specific pages. I have a master page which has children and default.aspx and services.aspx are ones of the children of Master page. What I want to is when user navigates Default.aspx or Services.aspx,system should apply DefaultCSS file otherwise I want to apply some ordinary css file.

我该如何做，对于这个问题什么样的做法会更好。

How can I do that and for this question what kind of practice would be better.

提前感谢。

推荐答案

我想我找到了我要找的东西：

I think I've found what I am looking for :

protected void Page_Init(object sender, EventArgs e)
    {
        HtmlLink css = new HtmlLink();
        css.Href = "css/fancyforms.css";
        css.Attributes["rel"] = "stylesheet";
        css.Attributes["type"] = "text/css";
        css.Attributes["media"] = "all";
        Page.Header.Controls.Add(css);
    }

同样MSDN描述如何实现这一点： HtmlLink Class

Also MSDN was describing how to achieve this : HtmlLink Class
