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.

Equals(DateTime)

Devuelve un valor que indica si el valor de esta instancia equivale al valor de la instancia de DateTime especificada.

public:
 virtual bool Equals(DateTime value);
public bool Equals (DateTime value);
override this.Equals : DateTime -> bool
Public Function Equals (value As DateTime) As Boolean

Parámetros

value
DateTime

Objeto que se va a comparar con esta instancia.

Devoluciones

Boolean

true si el parámetro value es igual al valor de esta instancia; en caso contrario, false.

Implementaciones

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 .
