EF orDErBy

LINQ 按多个字段排序(orderby、thenby、Take) orderby 子句解析为 OrderBy()方法,orderby descending 子句解析为OrderBy Descending()方法: var racers = Formula1.GetChampions(). Where(r = > r.Country == "Brazil"). OrderByDescending(...

new order是新来的订单比如说客人刚点好菜送到厨房的单last order是最后一张一般是餐厅关门前问客人是否还要加东西excuse me,930pm is our last order.would like to order anything else?大概这样用

利用扩展方法OrderByDescending对数组进行降序排序 using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace ConsoleApplication4{ class Program { static void Main(string[] args) { int[] a = { 1, 2...

private static IEnumerable Sort(IEnumerable source, string propertyName, bool asc) { Func func = s => s.GetType()....

a => a.GetType().GetProperty("你的参数")
