Equals(Object) |
Devuelve un valor que indica si esta instancia equivale a un objeto especificado. |
Equals(DateTime, DateTime) |
Devuelve un valor que indica si dos instancias de DateTime tienen el mismo valor de fecha y hora. |

Ejemplos
En el siguiente ejemplo se muestra el Equals método.
using System;
public class Application
{
public static void Main()
{
// Create some DateTime objects.
DateTime one = DateTime.UtcNow;
DateTime two = DateTime.Now;
DateTime three = one;
// Compare the DateTime objects and display the results.
bool result = one.Equals(two);
Console.WriteLine("The result of comparing DateTime object one and two is: {0}.", result);
result = one.Equals(three);
Console.WriteLine("The result of comparing DateTime object one and three is: {0}.", result);
}
}
// This code example displays the following:
//
// The result of comparing DateTime object one and two is: False.
// The result of comparing DateTime object one and three is: True.
open System
// Create some DateTime objects.
let one = DateTime.UtcNow
let two = DateTime.Now
let three = one
// Compare the DateTime objects and display the results.
let result = one.Equals two
printfn $"The result of comparing DateTime object one and two is: {result}."
let result2 = one.Equals three
printfn $"The result of comparing DateTime object one and three is: {result2}."
// This code example displays the following:
//
// The result of comparing DateTime object one and two is: False.
// The result of comparing DateTime object one and three is: True.
Module Application
Sub Main()
' Create some DateTime objects.
Dim one As DateTime = DateTime.UtcNow
Dim two As DateTime = DateTime.Now
Dim three As DateTime = one
' Compare the DateTime objects and display the results.
Dim result As Boolean = one.Equals(two)
Console.WriteLine("The result of comparing DateTime object one and two is: {0}.", result)
result = one.Equals(three)
Console.WriteLine("The result of comparing DateTime object one and three is: {0}.", result)
End Sub
End Module
' This code example displays the following:
'
' The result of comparing DateTime object one and two is: False.
' The result of comparing DateTime object one and three is: True.
Comentarios
La instancia actual y value
son iguales si sus Ticks valores de propiedad son iguales. Sus Kind valores de propiedad no se consideran en la prueba de igualdad.
Este método implementa la System.IEquatable<T> interfaz y funciona ligeramente mejor que el Equals método porque el value
parámetro no tiene que convertirse en un objeto.
