推荐答案

以下是您要阅读的主题:

1)母版页
2)部分视图
3)CSS样式

一个好的MVC方法将是创建一个局部视图，该视图在UL列表中呈现一些LI元素.

部分视图将在您的母版页上调用/渲染，从而使其在整个站点范围内都可用.

您将使用CSS使UL/LI元素看起来像菜单，而不仅仅是项目符号列表.

您当然可以使用ASP.NET成员资格，Linq to SQL等.有关MVC的Google文章，请访问Google或查看 ^ ]很好开始.

干杯.

Here are the topics you''ll want to read up on:

1) Master pages
2) Partial views
3) CSS styling

A good MVC approach to this would be creating a partial view that renders some LI elements in a UL list.

The partial view will be called/rendered on your master page, thus making it available site-wide.

You''ll use CSS to make the UL/LI elements look like a menu instead of just a bulleted list.

You can, of course, use ASP.NET membership, Linq to SQL etc. Google for ScottGu''s article''s on MVC, or check out the ASP.NET MVC site[^] for a good start.

如果使用HtmlHelper Extension方法创建菜单，例如:

<％= Html.RenderMenu()％>
您可以使用HtmlHelper实例查看请求上下文并确定您所在的页面.一旦有了这个，您就可以查找(数据库，配置，菜单数据所在的位置...)要呈现的子菜单.

以下是一些可以让您指出我认为正在寻找的方向的信息:

公共静态MvcHtmlString RenderMenu(this HtmlHelper html)
{var somePage = Html.ViewContext.HttpContext.Request.RawUrl;
var menu = lookupMenuBasedOnPage(somePage);
返回MvcHtmlString.Create(menu.Render());

If you create the menus using an HtmlHelper Extension method like:

<%= Html.RenderMenu() %>
you can use the HtmlHelper instance to look at the request context and determine what page you are on. Once you have this you can lookup (database, configuration, where ever your menu data is...) which submenu to render.

Heres something to get you point in the direction I think you are looking for:

public static MvcHtmlString RenderMenu(this HtmlHelper html)
{ var somePage = Html.ViewContext.HttpContext.Request.RawUrl;
var menu = lookupMenuBasedOnPage(somePage);
return MvcHtmlString.Create(menu.Render());
