ASP.NET：根据web.config文件中的位置配置显示或隐藏页面中的链接

Question

I have an ASP.NET web site with some locations in the web.config file, eg

<location path="SomeWhere">
  <system.web>
    <authorization>
      <allow roles="some-role"/>
      <deny users="*"/>
    </authorization>
  </system.web>
</location>

Then, in the master page for the site, I have a set of links, and I would like to show or hide some of the links according to the user's roles. I am currently doing this:

<% if (HttpContext.Current.User.IsInRole("some-role")) { %>
  <asp:HyperLink ID="SomeLink" runat="server" 
    NavigateUrl="~/SomeWhere/">Somewhere</asp:HyperLink>
<% } %>                 

I would like to avoid duplicating the role information in the web.config file and in the page code, and to replace the above check with something like

<% if (UserCanAccessLocation("Somewhere")) { %>
  <asp:HyperLink ID="SomeLink" runat="server" 
    NavigateUrl="~/SomeWhere/">Somewhere</asp:HyperLink>
<% } %>                 

Is this possible?

我记得的唯一方法-获取该URL的SiteMapNode并使用IsAccessibleToUser方法进行检查。
