关于LINQ一个简单例子

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace ConsoleApplication1
{
    class Program
    {
       
        static void Main(string[] args)
        {
            
            var A = new[] { 3, 4, 6, 7 };
            var B = new[] { 2, 2, 3, 5, 1 };
            var somInts = from a in A
                          from b in B
                          where a > 4 && b <= 2
                          select new { a, b, sum = a + b };
            foreach (var a in somInts)
            {
                Console.WriteLine(a);
            }
        

            Console.Read();



        }
    }
}
