c# - c# 比较当前windows用户和AD组

Question

我正在尝试获取当前的 windows 用户并查看该用户是否属于 Active Directory 中的某个组。用户名信息找到“Harper\TSmith”，这看起来不错，但是当我到达

UserPrincipal uPrincipal = Psearch.FindOne() as UserPrincipal

行 UPrincipal 为空。想不通为什么。我在底部还有一个验证器类，它作为布尔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;
    }

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

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