c＃将当前Windows用户与AD组进行比较

Question

我正在尝试抓取当前的Windows用户，看看该用户是否属于Active Directory中的某个组。用户名信息找到“Harper \ TSmith”，这似乎很好但是当我到达

时

UserPrincipal uPrincipal = Psearch.FindOne() as UserPrincipal

行UPrincipal为空。无法弄清楚为什么。我在底部还有一个验证器类，它作为一个bool方法来查看它们是否属于该特定组。

PrincipalContext principalCtx = new PrincipalContext(ContextType.Domain);
            UserPrincipal findUser = new UserPrincipal(principalCtx);
            //findUser.Name = Environment.UserName;
            findUser.Name = WindowsIdentity.GetCurrent().Name;
            PrincipalSearcher pSearch = new PrincipalSearcher();
            pSearch.QueryFilter = findUser;
            UserPrincipal uPrincipal = pSearch.FindOne() as UserPrincipal;

            Validator validate = new Validator();
            //validate.IsUserInGroup("VisualOne", uPrincipal);

            if (validate.IsUserInGroup("MyGroup", uPrincipal))
            {
                var MemberShipForm = new Membership();
                MemberShipForm.Show();
            }



public bool IsUserInGroup(string groupName, UserPrincipal user)
    {
        PrincipalContext context = new PrincipalContext(ContextType.Domain, "Harper");
        GroupPrincipal group = GroupPrincipal.FindByIdentity(context, "MyGroup");

        if (user.IsMemberOf(group))
        {
            return true;
        }
        return false;
    }

Answer 1

PrincipalContext principalCtx = new PrincipalContext(ContextType.Domain);
UserPrincipal uPrincipal = UserPrincipal.Current;

 if (validate.IsUserInGroup("MyGroup", uPrincipal))
            {
                var MemberShipForm = new Membership();
                MemberShipForm.Show();
            }
