Question

如何对实体框架返回的对象的内部集合进行排序？

public class X
{
   public string Field {get; set;}
   public EntityCollection<Y> Ys {get; set;}
}

public class Y
{
   public string Field {get; set;}
}

from x in entities.Xs
orderby x.Field
select x

有没有办法修改此LINQ查询以返回X对象并对Y对象进行排序？或者我必须在Y列表返回时手动对其进行排序？

修改

此代码必须返回X类型对象的集合，匿名输入不符合当前项目的要求。

var sortedList = from x in entities.Xs
                 orderby x.Field
                 select new {
                   Field = x.Field,
                   y = (select y in x.Ys
                        orderby y.Field
                        select y)
                 };

<强>编辑：如果您不想要匿名类型，请执行以下操作：

var sortedList = from x in entities.Xs
                 orderby x.Field
                 select new X {
                   Field = x.Field,
                   y = (select y in x.Ys
                        orderby y.Field
                        select y)
                 };
