LINQ语句的两种语法实现方式

using System;
using System.Linq;

namespace LINQ语法实现
{
    class Program
    {
        static void Main(string[] args)
        {
            int[] a = { 3,1,2,4};

            //1.Query syntax
            var Query1 = from num in a
                         where num % 2 == 0
                         orderby num
                         select num;
            foreach (var i in Query1)
            {
                Console.WriteLine("{0}", i);
            }
            Console.WriteLine();

            //2.Method syntax
            var Query2 = a.Where(n => n % 2 == 0).OrderBy(n => n);
            foreach (var j in Query2)
            {
                Console.WriteLine("{0}", j);
            }
        }
    }
