NHibernate Criteria.AddOrder(Order.Asc("Column.Property"))

Question

我有一个OrderEntity,它有一个属性OrderStatistics,它有一个属性CreateDate.它看起来像Order.OrderStatistics.CreateDate.

我想获取所有订单并通过CreateDate对它们进行排序.

1. fetchQuery.UnderlyingCriteria.AddOrder(Order.Asc("OrderStatistics.CreateDate"))不会吵闹

2. fetchQuery.UnderlyingCriteria.AddOrder(Order.Asc("CreatorName"))有效

   我怎样才能完成一项工作？

谢谢,

Answer 1

fetchQuery
    .UnderlyingCriteria
    .CreateAlias("OrderStatistics", "stats")
    .AddOrder(Order.Asc("stats.CreateDate"))

要么

OrderStatistic stats = null;
fetchQuery
    .CreateAlias(order => order.OrderStatistics, () => stats)
    .OrderBy(() => stats.CreateDate);
