推荐答案

一点都不急.为您工作的人没有紧迫感.

有内置的ASP.NET菜单控件吗?如果没有，您在使用什么?发布一些代码将有助于我们缩小范围.

有多少种不同的权限组合?您可以用代码动态地构建菜单吗?这就是我的目标，发出菜单代码并检查每个项目是否允许.

It''s not urgent at all. The people doing your job for you, feel no sense of urgency.

Is there an ASP.NET menu control built in ? If not, what are you using ? Posting some code would help us to narrow that down.

How many different combinations of permissions are there ? Can you build the menu dynamically in code ? That''s what I''d aim to do, to emit the menu code and check each item to see if it is allowed.

您可以使用sql表或站点地图根据用户权限和角色来绑定菜单.
试试这个:

Hi,
You can use either your sql table or sitemap to bind the menu based upon the user privilege and roles.
Try this:

最近，我开发了一个类似的网站.我使用了站点地图来添加菜单项，并使用LINQ根据用户角色在站点地图中添加或删除节点.如果您知道使用LINQ查询，那将非常容易.

取得更多结果.

我在下面使用了代码.

Recently I developed a similar site. I used sitemap to add menu items and LINQ to add or remove the nodes from the sitemap based on user roles. Its quite easy if you know working with LINQ queries.

The links below would be useful try out..

Bing for more results.

I used code below.

string sUserGroup = UserGroup.TrimEnd(';');
string[] arrUserGroup = sUserGroup.Split(';');
//string dummy1 = Server.MapPath("~\\Web.sitemap");
XDocument master = XDocument.Load(Server.MapPath("~\\Web.sitemap"));

XElement xelement = null, xElement = new XElement("siteMap");
xElement.Add(new XElement("siteMapNode", new XAttribute("title", "Home")));
foreach (string s in arrUserGroup)
{
    if (s.Equals("1500") || s.Equals("2500") || s.Equals("3500"))
    {
        //Dont add these---> Will be handled later (Meant for checker transactions)
    }
    else
    {
        System.Diagnostics.Debug.WriteLine("INFO", "Inside FOR-1");
        System.Diagnostics.Debug.WriteLine("INFO", s);

        var v = from e1 in master.Descendants("siteMapNode")
                where e1.Attribute("id").Value == s
                select e1;
        foreach (XElement xe in v)
        {
            System.Diagnostics.Debug.WriteLine("INFO", "Inside FOR-2");
            xelement = new XElement(xe);
        }

        xElement.Element("siteMapNode").Add(xelement);
        xElement.Save(Server.MapPath("~\\Role.sitemap"));
    }
}
