推荐答案

如果我理解这一点正确...

If I have understood this correctly...

如果您的列表是母版页上...

If your list is on the master page...

<ul runat="server" id="list">
    <li runat="server" id="home">Home</li>
    <li runat="server" id="news">News</li>
</ul>

...那么您可以将您的内容网页上做到这一点...

...then you can do this on your content page...

Control list = this.Page.Master.FindControl("list");

然后，李对象将在列表对象控制 - 例如 list.Controls 。或者，你可以做...

Then the li objects will be controls in the list object - e.g. list.Controls. Or you can do...

Control home = this.Page.Master.FindControl("list").FindControl("home");

...找到列表控件的具体控制。

...to find specific controls of the list control.

在使用上的HTML =服务器控制服务器端等价的对象将 HtmlGenericControl

When using the runat="server" on the HTML controls the server side equivalent object will be HtmlGenericControl.

如果你想一类适用于 LI 标签，你会做什么是投在 LI 对象到 HtmlGenericControl 并然后使用属性属性。例如...

If you want to apply a class to the LI tags what you would have to do is cast the LI object to a HtmlGenericControl and then use the Attributes property. For example...

HtmlGenericControl home = (HtmlGenericControl)this.Page.Master.FindControl("list").FindControl("home");

home.Attributes["class"] = "className";
