Si other es un Bytevalor , , SByteInt16Int32, UInt16, o UInt32 , se convierte implícitamente en un Int64 valor cuando se llama al CompareTo(Int64) método .

En el ejemplo siguiente se muestra el uso del CompareTo(BigInteger) método para ordenar una lista de StarInfo objetos. Cada StarInfo objeto proporciona información sobre el nombre de una estrella y su distancia desde la Tierra en millas. StarInfo implementa la IComparable<T> interfaz , que permite StarInfo ordenar los objetos por clases de colección genéricas. Su IComparable<T>.CompareTo implementación solo ajusta una llamada a CompareTo(BigInteger).

using System;
using System.Collections.Generic;
using System.Numerics;

public struct StarInfo : IComparable<StarInfo>
{
   // Define constructors.
   public StarInfo(string name, double lightYears)
   {
      this.Name = name;

      // Calculate distance in miles from light years.
      this.Distance = (BigInteger) Math.Round(lightYears * 5.88e12);
   }

   public StarInfo(string name, BigInteger distance)
   {
      this.Name = name;
      this.Distance = distance;
   }

   // Define public fields.
   public string Name;
   public BigInteger Distance;

   // Display name of star and its distance in parentheses.
   public override string ToString()
   {
      return String.Format("{0,-10} ({1:N0})", this.Name, this.Distance);
   }

   // Compare StarInfo objects by their distance from Earth.
   public int CompareTo(StarInfo other)
   {
      return this.Distance.CompareTo(other.Distance);
   }
}

Imports System.Collections.Generic
Imports System.Numerics

Public Structure StarInfo : Implements IComparable(Of StarInfo)
   ' Define constructors.
   Public Sub New(name As String, lightYears As Double)
      Me.Name = name
      ' Calculate distance in miles from light years.
      Me.Distance = CType(Math.Round(lightYears * 5.88e12), BigInteger)
   End Sub
   
   Public Sub New(name As String, distance As BigInteger)
      Me.Name = name
      Me.Distance = distance
   End Sub
   
   ' Define public fields.
   Public Name As String
   Public Distance As BigInteger

   ' Display name of star and its distance in parentheses.
   Public Overrides Function ToString() As String
      Return String.Format("{0,-10} ({1:N0})", Me.Name, Me.Distance)
   End Function

   ' Compare StarInfo objects by their distance from Earth.
   Public Function CompareTo(other As starInfo) As Integer _
                   Implements IComparable(Of StarInfo).CompareTo
      Return Me.Distance.CompareTo(other.Distance)
   End Function                
End Structure

A continuación, el código siguiente crea una instancia de cuatro StarInfo objetos y los almacena en un objeto genérico List<T> . Después de llamar al List<T>.Sort método , StarInfo los objetos se muestran en orden de su distancia desde la Tierra.

public class Example
{
   public static void Main()
   {
      StarInfo star;
      List<StarInfo> stars = new List<StarInfo>();

      star = new StarInfo("Sirius", 8.6d);
      stars.Add(star);
      star = new StarInfo("Rigel", 1400d);
      stars.Add(star);
      star = new StarInfo("Castor", 49d);
      stars.Add(star);
      star = new StarInfo("Antares", 520d);
      stars.Add(star);

      stars.Sort();

      foreach (StarInfo sortedStar in stars)
         Console.WriteLine(sortedStar);
   }
}
// The example displays the following output:
//       Sirius     (50,568,000,000,000)
//       Castor     (288,120,000,000,000)
//       Antares    (3,057,600,000,000,000)
//       Rigel      (8,232,000,000,000,000)

Module Example
   Public Sub Main()
      Dim star As StarInfo
      Dim stars As New List(Of StarInfo)
      
      star = New StarInfo("Sirius", 8.6d)
      stars.Add(star)
      star = New StarInfo("Rigel", 1400d)
      stars.Add(star)
      star = New StarInfo("Castor", 49d)
      stars.Add(star)
      star = New StarInfo("Antares", 520d)
      stars.Add(star)
      
      stars.Sort()
      
      For Each star In stars
         Console.WriteLine(star)
      Next   
   End Sub
End Module
' The example displays the following output:

Esta sobrecarga del CompareTo método implementa el IComparable.CompareTo método . Los objetos de colección no genéricos usan para ordenar los elementos de la colección.

El obj parámetro debe ser uno de los siguientes:

• Objeto cuyo tipo de tiempo de ejecución es BigInteger.

• Variable Object cuyo valor es null. Si el valor del obj parámetro es null, el método devuelve 1, lo que indica que la instancia actual es mayor que obj.
