The extension method of C # implements array sorting in LINQ

First define an array, int[] a = {3,1,2,4}, we want to simply implement the ordering of the array, but the a array is under system space, there is no order by (), this is the introduction of namespaces using You can see the method again after System.Linq. Here's a simple example:

Using System;using System.linq;namespace object initializer {class program    {        static void Main (string[] args)        {            int[] A = {3,1,2,4};            var result = A.orderby (t=>t);            foreach (var i in result)            {                Console.WriteLine ("{0}", i);            }            Console.WriteLine ();}}}
