Retourne un code de hachage pour cette instance.

Espace de noms : System
Assembly : mscorlib (dans mscorlib.dll)

public override int GetHashCode ()

Valeur de retour

Code de hachage entier signé 32 bits.

Deux objets TimeSpan peuvent posséder le même code de hachage, même s'ils représentent différentes valeurs temporelles.

L'exemple de code suivant génère les codes de hachage de plusieurs objets TimeSpan à l'aide de la méthode GetHashCode.

// Example for the TimeSpan.GetHashCode( ) method.
using System;

class GetHashCode
{
    static void DisplayHashCode( TimeSpan interval )
    {
        // Create a hash code and a string representation of 
        // the TimeSpan parameter.
        string  timeInterval = interval.ToString( );
        int     hashCode = interval.GetHashCode( );

        // Pad the end of the TimeSpan string with spaces if it 
        // does not contain milliseconds.
        int pIndex = timeInterval.IndexOf( ':' );
        pIndex = timeInterval.IndexOf( '.', pIndex );
        if( pIndex < 0 )   timeInterval += "        ";

        Console.WriteLine( "{0,22}   0x{1:X8}, {1}", 
            timeInterval, hashCode );
    }

    static void Main( )
    {
        Console.WriteLine(
            "This example of TimeSpan.GetHashCode( ) generates " +
            "the following \noutput, which displays " +
            "the hash codes of representative TimeSpan \n" +
            "objects in hexadecimal and decimal formats.\n" );
        Console.WriteLine( "{0,22}   {1,10}", 
            "TimeSpan        ", "Hash Code" );
        Console.WriteLine( "{0,22}   {1,10}",

        DisplayHashCode( new TimeSpan( 1 ) );
        DisplayHashCode( new TimeSpan( 0, 0, 0, 0, 1 ) );
        DisplayHashCode( new TimeSpan( 0, 0, 1 ) );
        DisplayHashCode( new TimeSpan( 0, 1, 0 ) );
        DisplayHashCode( new TimeSpan( 1, 0, 0 ) );
        DisplayHashCode( new TimeSpan( 36000000001 ) );

        DisplayHashCode( new TimeSpan( 1, 0, 0, 0 ) );

        DisplayHashCode( new TimeSpan( 1, 0, 0, 0, 1 ) );
        DisplayHashCode( new TimeSpan( 1, 0, 0, 1 ) );
        DisplayHashCode( new TimeSpan( 100, 0, 0, 0 ) );
        DisplayHashCode( new TimeSpan( 100, 0, 0, 0, 1 ) );
        DisplayHashCode( new TimeSpan( 100, 0, 0, 1 ) );
    }
