nhibernate5.5.0 JoinEntityAlias 多个 ProjectionList 结果不起作用

Question

        public IList<RoomEcologyDto> GetNonassetJoinPersonData(ExpressionCondition<UVNonAssetAll> nonassetCondition)
        {
            var lambda_contract_effect = bizUTRenterContract.lambda_effect_condition();
            var lambda_contract = lambda_contract_effect.ConditionExpression;
            var lambda_nonasset = nonassetCondition.ConditionExpression;
            UVNonAssetAll a = null;
            UTRenterContract b = null;
            UTRenterApplyIn c = null;
            var sqlQuery = dbAccess.Session.QueryOver(() => a).Where(lambda_nonasset)
                .JoinEntityAlias(() => b, Restrictions.And(Restrictions.Where(() => a.keyId == b.NonAssetID), Restrictions.Where(lambda_contract)), JoinType.LeftOuterJoin)
                .JoinEntityAlias(() => c, Restrictions.Where(() => c.ID == b.ApplyID), JoinType.LeftOuterJoin);
            ;
            sqlQuery = sqlQuery.Select(
                Projections.ProjectionList()
                .Add(Projections.RootEntity())
                .Add(Projections.Property(nameof(b)+"."+nameof(UTRenterContract.ID)))//=> not error,sql right,but res=[{a:UVNonAssetAll}]
                .Add(Projections.Select<UTRenterContract>(x => x.ID), nameof(RoomEcologyDto.renterContractId)) // sqlQuery.List<Hashtable>().error::“could not resolve property: ID of: HYGZFSys.Entity.UVNonAssetAll”
                .Add(Projections.Property<UTRenterContract>(x => x.ID), nameof(RoomEcologyDto.renterContractId))// sqlQuery.List<Hashtable>().error could not resolve property: ID of: HYGZFSys.Entity.UVNonAssetAll”
                )
                ;
            sqlQuery = sqlQuery.TransformUsing(Transformers.AliasToEntityMap);
            var res = sqlQuery.List<Hashtable>();
            return new List<RoomEcologyDto>();
        }

1. 字符串属性有效，但 hashtale 结果仍然是 [{a:UVNonAssetAll}]
2. 如何拉姆达？
3. 转换为 RoomEcologyDto？ ，当我使用变压器时=> 无法在类“System.RuntimeType
”中找到属性“a”的设置器

必须对齐

            }
            projection.Add(Projections.Property(alignName), propertyName);
