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...

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(...

list.OrderByDescending(i => i.a).ThenByDescending(i => i.b);

Dictionary dic1 = new Dictionary(); dic1.Add("ddd","123"); dic1.Add("aaa", "123"); dic1.Add("ccc", "123"); dic1.Add("fff", "123"); dic1.Add("eee", "123"); dic1.Add("bbb", "123"); Dictionary dic1Asc = dic1.OrderBy(o => o.Key).To...

datarow=datarow.OrderByDescending(x=>x["name"]).ToArray();

查询并填充数据

order by [列名] [ASC(按升序排序)|DESC(按降序排序)]

var n = from p in numbers where p%2 == 0 orderby p descending select p;

Dictionary dic1 = new Dictionary(); dic1.Add("ddd","123"); dic1.Add("aaa", "123"); dic1.Add("ccc", "123"); dic1.Add("fff", "123"); dic1.Add("eee", "123"); dic1.Add("bbb", "123"); Dictionary dic1Asc = dic1.OrderBy(o => o.Key).To...

布尔只有两种状态,所以直接用 OrderBy跟OrderByDescending就能正序跟倒序拍,没必要多计算 .OrderBy(o => o.字段); .OrderByDescending(o => o.字段)...
