Ejemplos

En el ejemplo siguiente se muestra el Compare 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
Module Example
   Public Sub Main()
      Dim date1 As Date = #08/01/2009 12:00AM#
      Dim date2 As Date = #08/01/2009 12:00PM#
      Dim result As Integer = DateTime.Compare(date1, date2)
      Dim relationship As String
      
      If result < 0 Then
         relationship = "is earlier than"
      ElseIf result = 0 Then
         relationship = "is the same time as"         
      Else
         relationship = "is later than"
      End If

Comentarios

Para determinar la relación de t1 a 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 horas en la misma zona horaria.Before comparing DateTime objects, ensure that the objects represent times in the same time zone.
