## Ejemplos

En el siguiente ejemplo se Compare muestra el método.The following example demonstrates the Compare method.

``````using System;

public class Example
{
public static void Main()
{
DateTime date1 = new DateTime(2009, 8, 1, 0, 0, 0);
DateTime date2 = new DateTime(2009, 8, 1, 12, 0, 0);
int result = DateTime.Compare(date1, date2);
string relationship;

if (result < 0)
relationship = "is earlier than";
else if (result == 0)
relationship = "is the same time as";
else
relationship = "is later than";

Console.WriteLine("{0} {1} {2}", date1, relationship, date2);
}
}
// The example displays the following output:
//    8/1/2009 12:00:00 AM is earlier than 8/1/2009 12:00:00 PM

## Comentarios

Para determinar la relación de `t1` con `t2`, el Compare método compara la Ticks propiedad de `t1` y `t2` , pero omite su Kind propiedad.To determine the relationship of `t1` to `t2`, the Compare method compares the Ticks property of `t1` and `t2` but ignores their Kind property. Antes de comparar DateTime objetos, asegúrese de que los objetos representan las horas de la misma zona horaria.Before comparing DateTime objects, ensure that the objects represent times in the same time zone.
