我有

网站地图像这样：

<?xml version="1.0" encoding="utf-8" ?>
<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >
    <siteMapNode url="" title=""  description="">
        <siteMapNode url="~/Home.aspx" title="Home"  description=" this is the home page" />
        <siteMapNode url="~/ProjectList.aspx" title="Project List"  description="Approved projects" />
        <siteMapNode url="" title="Project Choices" description="">
            <siteMapNode url="~/StudentChoices.aspx" title="Student Project Choices"  description="" />
            <siteMapNode url="~/StaffChoices.aspx" title="Supervisor Project Choices"  description="" />
        </siteMapNode>
        <siteMapNode url="~/AllocationList.aspx" title="Project Allocation List"  description="" />
        <siteMapNode url="" title="Submit Proposal" description="" >
            <siteMapNode url="~/submit.aspx" title="New Proposal"  description="new proposal" />
            <siteMapNode url="~/reSubmit.aspx" title="Re-Submit Proposal" description="re submit proposal"/>
        </siteMapNode>
        <siteMapNode url="~/StaffRecords.aspx" title="Staff Records"  description="" >
            <siteMapNode url="~/addStaff.aspx" title="Add new Staff" description="" />
        </siteMapNode>
        <siteMapNode url="~/StudentRecords.aspx" title="Student Records"  description="" />
        <siteMapNode url="~/Administration.aspx" title="Administration"  description="" />
    </siteMapNode>
</siteMap>

我使用此站点地图创建菜单项：如下所示：

<asp:Menu ID="Menu1" runat="server" Orientation="Horizontal"
                BackColor="#33CCFF" Font-Overline="False" DataSourceID="SiteMapDataSource1"
                Font-Size="Larger" ForeColor="Black" ItemWrap="True" StaticDisplayLevels="2"
                StaticSubMenuIndent="60px" Width="100%" OnMenuItemDataBound="Menu1_MenuItemDataBound">
                <DynamicHoverStyle BackColor="#9999FF" ForeColor="Black" />
                <DynamicMenuItemStyle BackColor="#0099FF" ForeColor="Black" />
                <DynamicMenuStyle BackColor="#0099FF" />
                <DynamicSelectedStyle BackColor="#0099FF" ForeColor="Black" />
            </asp:Menu>

<asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" />

在代码Be-Hide上，我写了以下内容：

protected void Menu1_MenuItemDataBound(object sender, MenuEventArgs e)
    {
        //string role = Session["Roles"].ToString();
        string AdminRole = ConfigurationManager.AppSettings["AdminRole"];
        string StaffRole = ConfigurationManager.AppSettings["StaffRole"];
        string StudentRole = ConfigurationManager.AppSettings["StudentRole"];
        if (StaffRole == "Staff")
        {
            if (e.Item.Text == "Project Choices" ||
                e.Item.Text == "Staff Records" ||
                e.Item.Text == "Student Records")
            {
                Menu1.Items.Remove(e.Item);
            }
        }
    }

和像这样的网络配置

<appSettings>
        <add key="AdminRole" value="Admin"/>
        <add key="StaffRole" value="Staff"/>
        <add key="StudentRole" value="Student"/>
    </appSettings>

但我仍然能够看到那些菜单，我无法找出为什么它没有删除，谁能告诉我为什么？显示示例代码。

siteMapNode已经提供了一个名为 roles 的属性。此属性保存可以访问站点该区域的roles。

例如，项目列表应如下所示：

<siteMapNode url="~/ProjectList.aspx" 
 title="Project List"  
 description="Approved projects" 
 roles="AdminRole"/>

有一个Security trimming，与ASP.NET Membership结合使用，可以根据用户角色管理访问权限。

你应该看看这里： ASP.NET 站点地图安全修整

 The easiest way  to use a SiteMapProvider is  to configure with SecurityTrimmingEnabled = true.
 Add this under Web.Config file 
<siteMap enabled="true" defaultProvider ="AspNetXmlSiteMapProvider" >
  <providers>
    <clear/>
    <add siteMapFile="Web.sitemap" name="AspNetXmlSiteMapProvider" type="System.Web.XmlSiteMapProvider" securityTrimmingEnabled="true" />
  </providers>
</siteMap>
try to add the roles to the site map like this
<siteMapNode url="~/StaffRecords.aspx" title="Staff Records"  description=""     roles="StaffRole">
  <siteMapNode url="~/addStaff.aspx" title="Add new Staff" description="" />
</siteMapNode>
