用sitemap做主页的菜单栏

首先打开vs--> 新建项-->选择站点地图.

站点地图建好了  其中具体的节点根据自己情况配好就行。

接下来是两个非常重要的类：

using System.Collections.Generic;
using System.Web.Routing;

        /// </summary>
        public SiteMapNode()
        {
            RouteValues = new RouteValueDictionary();
            ChildNodes = new List<SiteMapNode>();
        }

        /// <summary>

    }
}

这两个类完全可以直接拿去用，只是第二个类里面有一些判断要改一下（登陆成功是否显示），其他都不用动。

最后来看看在母版页里如何调用：
