在Master Page中快速创建菜单

Question

您好我有一个网站，其主菜单根据用户的角色填写 这需要在母版页中有很多菜单处理代码，事情正常 我很想知道，这种方法是否有任何性能下降 或者是否有更好的方式以这种方式放置菜单（我没有使用默认的asp.net Db和帐户等）这是我的代码：

DAO dao = new DAO();
protected void Page_Load(object sender, EventArgs e)
{ DispMenues(); }

protected void btnLogin_Click(object sender, EventArgs e)
{ /* Login Mechanism */ }

private void DispMenues()
{ // Menu is main menue on the page
    Menu.Items.Clear();
    MenuItem mnuHome = new MenuItem("&nbsp&nbspHome&nbsp&nbsp", "Home");
    mnuHome.NavigateUrl = "~/index.aspx";
    Menu.Items.Add(mnuHome);

    if (Session["urole"] != null)
        switch (Session["urole"].ToString())
        {
            case "admin":
                AdmMenu();
                break;
            case "supervisor":
                SupMenu();
                break;
            case "deo":
                DEOMenu();
                break;
            default:
                Response.Redirect("index.aspx");
                break;
        }

}

这很好。
如果我是你，我会在你的商品名称中使用css而不是“＆amp; nbsp” 此外，您可以使用带有... 5个参数（我认为）的MenuItem构造函数，包括NavigateUrl 或者你可以简单地使用默认构造函数并逐个初始化属性。

编辑：哦，另一件事......最好在菜单控件 DataBound事件中创建项目，你应该考虑使用SiteMap
