using System; using System.Collections.Generic; using System.Linq; namespace LINQtest { public class Child { public int Age { get; set; } } public class Parent { public Child[] Kids { get; set; } } public class MyLinq { public List<Parent> Parents { get; set; } } class Program { static void Main(string[] args) { Parent parentOne = new Parent(); parentOne.Kids = new Child[2]; parentOne.Kids[0] = new Child(); parentOne.Kids[0].Age = 1; parentOne.Kids[1] = new Child(); parentOne.Kids[1].Age = 2; Parent parentTwo = new Parent(); parentTwo.Kids = new Child[3]; parentTwo.Kids[0] = new Child(); parentTwo.Kids[0].Age = 5; parentTwo.Kids[1] = new Child(); parentTwo.Kids[1].Age = 7; parentTwo.Kids[2] = new Child(); parentTwo.Kids[2].Age = 6; Parent parentThree = new Parent(); parentThree.Kids = new Child[2]; parentThree.Kids[0] = new Child(); parentThree.Kids[0].Age = 3; parentThree.Kids[1] = new Child(); parentThree.Kids[1].Age = 4; MyLinq myLinq = new MyLinq(); myLinq.Parents = new ListPOI:(); myLinq.Parents.Add(parentOne); myLinq.Parents.Add(parentTwo); myLinq.Parents.Add(parentThree); int maxAge = myLinq.Parents.Max(parent => parent.Kids.Max(kid => kid.Age)); Console.WriteLine("Oldest kid is age of: " + maxAge); Console.WriteLine("Press any key"); Console.ReadKey(); } } }
int maxAge = myLinq.Parents.Max(parent => parent.Kids.Max(kid => kid.Age));Because for example code:
IEnumerable<int> maxAges = myLinq.Parents.Select(parent => parent.Kids.Max(kid => kid.Age));Will return collection of ages in list of parents.

One dummy example of LINQ:
using System; using System.Linq; namespace linqExamples { class Program { static void Main(string[] args) { string s = "Test"; var test = s.Select(d => "b"); foreach(var b in test) { Console.WriteLine(b); } Console.ReadKey(); } } }
