按实体框架中的子集合排序

我有一个实体框架模型，看起来像:

public class User
{
  public DateTime DateCreated {get;set;}
  publc virtual List<Car> Cars {get;set;}
}
public class Car
{
  public string ModelType {get;set;}
}

现在我想获得所有用户，并按DESC订购，以便拥有ModelType为"Sedan"的汽车的用户位于顶部。

在我的查询中，我正在通过包含属性"Cars"来做一些急于加载，但我不确定如何为子属性订购。

我使用基于此的通用存储库模式:http://www.asp.net/mvc/tutorials/getting-started-with-ef-using-mvc/implementing-the-repository-and-unit-of-work-patterns-in-an-asp-net-mvc-application

我的方法现在是这样的:

    public List<User> GetUsers()
    {
        return Get(orderBy: o => o.OrderByDescending(u => u.DateCreated), 
            includeProperties: "Cars").ToList();
    }

它有一个Get方法，看起来像

public virtual IEnumerable<TEntity> Get(
            Expression<Func<TEntity, bool>> filter = null,
            Func<IQueryable<TEntity>, IOrderedQueryable<TEntity>> orderBy = null,
            string includeProperties = "")
        {
            IQueryable<TEntity> query = dbSet;
            if (filter != null)
            {
                query = query.Where(filter);
            }
            foreach (var includeProperty in includeProperties.Split
                (new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries))
            {
                query = query.Include(includeProperty);
            }
            if (orderBy != null)
            {
                return orderBy(query).ToList();
            }
            else
            {
                return query.ToList();
            }
        }

OrderByDescending(u => u.Cars.Any(c => c.ModelType == "Sedan"));
