C# 对象模型数组与C数组相交的Nhibernate查询

假设我们有一个名为User的映射nhibernate对象模型，其中包含注册列表。我们还有一个包含有效注册列表的C数组

如何仅查询包含有效注册的用户

我尝试了以下方法：

Registration[] validRegistrations; // already populated
session.Query<User>().Where(usr => usr.Registrations.Intersect(validRegistrations).Any());

var results = from user in session.Query<User>()
              from registration in user.Registrations
              where validRegistrations.Contains(registration)
              select user;

当我尝试此操作时，会出现以下错误：IntersectResultOperator结果运算符当前不受支持

虽然不是最佳的，但类似的操作不起作用吗

var results = 
    session
        .Query<User>()
        .Where(usr => validRegistrations.Contains(usr.Registrations)
        .ToList();

如果您不介意切换到LINQ查询语法，我认为这会使它更具可读性，我相信您正在寻找以下内容：

Registration[] validRegistrations; // already populated
session.Query<User>().Where(usr => usr.Registrations.Intersect(validRegistrations).Any());

var results = from user in session.Query<User>()
              from registration in user.Registrations
              where validRegistrations.Contains(registration)
              select user;

以下解决方案相当于相交：

用户和注册是否双向映射？用户是否可以拥有无效的注册？
