比如说我们要从用户表customer和用户订单表orders中，查询上海的用户，在最近10个月中至少消费3笔满10快钱的用户的姓名和年龄。如果写成传统的方法，不知道要写多少代码，而且各种复杂的处理逻辑

var results = from customer in customers
              where customer.State == "WA"
              let custOrders = (from order in orders
                                where customer.ID == order.ID
                                select new { order.Date, order.Amount })
              where custOrders.Count(co => co.Amount >= 10 &&
                                     co.Date >= DateTime.Now.AddMonths(−10)) >= 3
              select new { customer.Name, customer.Age };<br><br>下面另附上一条分页的linq语句:<br>var productList=(from prod in db.Products<br>where prod.Type="零食" orderby prod.datatime select u).Skip(PageSize*(PageNum-1)).Take(PageSize);
