using System.Collections.Generic;
public class MainClass {
public static void Main() {

<source lang="csharp">using System;
using System.Linq;
using System.Collections;
using System.Collections.Generic;
public class MainClass {

==Using All to determine whether an array contains only odd numbers.==

<source lang="csharp">using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
public class MainClass {
public static void Main() {
int[] numbers = { 1, 11, 3, 19, 41, 65, 19 };
bool onlyOdd = numbers.All(n => n % 2 == 1);
Console.WriteLine("The list contains only odd numbers: {0}", onlyOdd);
}
