TimeSpan.GetHashCode Methode

Definition

Namespace:

System

Assemblys:

netstandard.dll, System.Runtime.dll

Quelle:

TimeSpan.cs

Gibt einen Hashcode für diese Instanz zurück.

C#

public override int GetHashCode();

Gibt zurück

Int32

Ein 32-Bit-Hashcode als ganze Zahl mit Vorzeichen.

Beispiele

Im folgenden Beispiel werden die Hashcodes mehrerer TimeSpan Objekte mithilfe der GetHashCode -Methode generiert.

C#

// 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( 0 ) );
        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( 0, 1, 0, 0, 1 ) );
        DisplayHashCode( new TimeSpan( 1, 0, 1 ) );
        DisplayHashCode( new TimeSpan( 1, 0, 0, 0 ) );
        DisplayHashCode( new TimeSpan( 864000000001 ) );
        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 ) );
    } 
}

Hinweise

Zwei TimeSpan Objekte verfügen möglicherweise über denselben Hashcode, obwohl sie unterschiedliche Zeitwerte darstellen.
