Igualdad en LINQ

Compara dos oraciones (enumerables) y determina si coinciden exactamente o no.

Operador	Descripción	Sintaxis de expresión de consulta de C #	Sintaxis de expresión de consulta de VB
SequenceEqual	Da como resultado un valor booleano si se encuentra que dos secuencias son idénticas entre sí	No aplica	No aplica

Ejemplo de SequenceEqual: método Enumerable.SequenceEqual

C#

using System;
using System.Collections.Generic;
using System.Linq;

namespace Operators {
   class SequenceEqual {
      static void Main(string[] args) {
      
         Pet barley = new Pet() { Name = "Barley", Age = 4 };
         Pet boots = new Pet() { Name = "Boots", Age = 1 };
         Pet whiskers = new Pet() { Name = "Whiskers", Age = 6 };

         List<Pet> pets1 = new List<Pet>() { barley, boots };
         List<Pet> pets2 = new List<Pet>() { barley, boots };
         List<Pet> pets3 = new List<Pet>() { barley, boots, whiskers };

         bool equal = pets1.SequenceEqual(pets2);
         bool equal3 = pets1.SequenceEqual(pets3);

         Console.WriteLine("The lists pets1 and pets2 {0} equal.", equal ? "are" :"are not");
         Console.WriteLine("The lists pets1 and pets3 {0} equal.", equal3 ? "are" :"are not");

         Console.WriteLine("\nPress any key to continue.");
         Console.ReadKey();
      }

      class Pet {
         public string Name { get; set; }
         public int Age { get; set; }
      }
   }
}

VB

Module Module1
   Sub Main()

      Dim barley As New Pet With {.Name = "Barley", .Age = 4}
      Dim boots As New Pet With {.Name = "Boots", .Age = 1}
      Dim whiskers As New Pet With {.Name = "Whiskers", .Age = 6}

      Dim pets1 As New System.Collections.Generic.List(Of Pet)(New Pet() {barley, boots})
      Dim pets2 As New System.Collections.Generic.List(Of Pet)(New Pet() {barley, boots})
      Dim pets3 As New System.Collections.Generic.List(Of Pet)(New Pet() {barley, boots, whiskers})

      Dim equal As Boolean = pets1.SequenceEqual(pets2)
      Dim equal3 As Boolean = pets1.SequenceEqual(pets3)

      Console.WriteLine("The lists pets1 and pets2 {0} equal.", IIf(equal, "are", "are not"))
      Console.WriteLine("The lists pets1 and pets3 {0} equal.", IIf(equal3, "are", "are not"))

      Console.WriteLine(vbLf & "Press any key to continue.")
      Console.ReadKey()
  
   End Sub

   Class Pet
      Public Property Name As String
      Public Property Age As Integer
   End Class
   
End Module

Cuando el código anterior de C # o VB se compila y ejecuta, produce el siguiente resultado:

The lists pets1 and pets2 are equal.
The lists pets1 and pets3 are not equal.

Press any key to continue.
