Csharp/C Sharp/LINQ/All

All with condition

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

  public static void Main(){
      int[] numbers = { 2, 6, 1, 56, 102 };
      Console.Write(numbers.All(e => e % 2 == 0) ? "Yes, they are" : "No, they aren"t");
  }

}

</source>

All with Predicate to Return True

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

   public static void Main() {
       string[] presidents = {"G123456", "H", "a", "H", "over", "Jack"};
       bool all = presidents.All(s => s.Length > 5);
       Console.WriteLine(all);
   }

}

</source>

All with string length

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

   public static void Main() {
       string[] presidents = {"G", "H", "a", "H", "over", "Jack"};
       bool all = presidents.All(s => s.Length > 3);
       Console.WriteLine(all);
   }

}

</source>

uses 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);
   }

}
