Linq 对string[]字符串数组进行排序 （升序降序乱序）

Posted 2021-03-17 xe2011

using System;
using System.Collections;
using System.Linq;

namespace ConsoleApp1 {
    class Program {
        static void Main(string[] args) {

            string[] array = { "a.m.", "a", "Smith", "Jones", "module", "zoology",
                                "youth", "Hsieh", "abdomen", "Xerox", "season",
                                "Luncheon", "transferable","macro","genuine" };
            //var array = from a in names orderby a ascending select a;//升序
            //var array = from a in names orderby a descending select a;//降序
            var array = from a in array orderby Guid.NewGuid() select a; //打乱顺序序，每次运行结果都不一样

            foreach (var item in array ) {
                Console.WriteLine(item);
            }
            Console.ReadKey();
        }
    }
}

升序排序

ascending 默认不指名就是ascending 升序

降序排序

descending 降序

//Linq 

var array = from a in names orderby a descending select a;//降序 

乱序排序

每次运行结果都不一样，

//Linq 

var array = from a in array orderby Guid.NewGuid() select a; //打乱顺序序，每次运行结果都不一样
