如何在Nhibernate查询中选择集合？

如何解决如何在Nhibernate查询中选择集合？

我在调整查询中的集合时遇到问题。

我已将问题分为三个阶段。

第一阶段：-我正在使用以下查询获取所有帐户。

var allAccountsQuery = session.QueryOver(() => accountAlias)
            .Where(account => !account.IsDeleted)
            .Inner.JoinAlias(account => account.Owner,() => ownerAlias,o => o.Id == owner.Id)
            .TransformUsing(new DistinctRootEntityResultTransformer());

第二阶段：-我正在将余额提取到我的帐户中。

AccountBalance accountBalance = null;
            allAccountsQuery = allAccountsQuery
                .Left.JoinAlias(account => account.AccountBalances,() => accountBalance,balance => !balance.IsDeleted)
                .TransformUsing(new DistinctRootEntityResultTransformer());

第3阶段：之后，我尝试使用投影条件操作根据以下条件填充一些属性。

allAccountsQuery = allAccountsQuery
                .SelectList(list => list
                    .Select(() => accountAlias.Id).WithAlias(() => accountAlias.Id)
                    .Select(() => accountAlias.AccountNumber).WithAlias(() => accountAlias.AccountNumber)
                    .Select(() => accountAlias.CoreAccountId).WithAlias(() => accountAlias.CoreAccountId)
                    .Select(() => accountAlias.SourceId).WithAlias(() => accountAlias.SourceId)
                    .Select(() => accountAlias.Changed).WithAlias(() => accountAlias.Changed)
                    .Select(
                        Projections.Conditional(
                            Subqueries.Exists(
                                QueryOver
                                .Of(() => history)
                                .Where(() => history.Account.Id == accountAlias.Id && history.ValidFrom <= dateToCheck && history.ValidTo >= dateToCheck)
                                .Select(x => x.Account.Id)
                                .DetachedCriteria) // this is the SUB-SELECT,Projections.SubQuery(
                                QueryOver
                                .Of(() => history)
                                .Where(() => history.Account.Id == accountAlias.Id)
                                .Select(x => x.AccountDescription)
                                .Take(1)
                            ),Projections.Property<Account>(p => p.Description)
                        )
                    )
                    .WithAlias(() => accountAlias.Description)
                )
                .TransformUsing(new DeepTransformer<Account>());

问题：现在，我想放下我从第二阶段获取的收藏集。经过一些研究，我发现下面的内容。让我知道正确的看法。
