您好lax4u;

Hi lax4u;

此查询仅通过在末尾使用SingleOrDefault方法返回一条记录，因此无需排序，或者我遗漏了什么。

This query only returns one record by the use of the SingleOrDefault method on the end so there is nothing to sort, or am I missing something.

return repository.GetQuery()
 .Where(x => x.CustomerID == customerID)
 .Include(x => x.Orders.Select(y => y.OrderDetails))
 .Include(x => x.Orders.Select(y => y.Payments))
 .SingleOrDefault();
