UTF8Encoding.GetHashCode Méthode

public:
 override int GetHashCode();

public override int GetHashCode ();

override this.GetHashCode : unit -> int

Public Overrides Function GetHashCode () As Integer

Retours

Code de hachage de l'instance actuelle.

Exemples

L’exemple suivant utilise la GetHashCode méthode pour retourner un code de hachage pour UTF8Encoding les instances. Notez que le code de hachage retourné par cette méthode dépend du constructeur utilisé pour créer l’objet UTF8Encoding .

using namespace System;
using namespace System::Text;
int main()
{
   
   // Many ways to instantiate a UTF8 encoding.
   UTF8Encoding^ UTF8a = gcnew UTF8Encoding;
   Encoding^ UTF8b = Encoding::UTF8;
   Encoding^ UTF8c = gcnew UTF8Encoding( true,true );
   Encoding^ UTF8d = gcnew UTF8Encoding( false,false );
   
   // But not all are the same.
   Console::WriteLine( UTF8a->GetHashCode() );
   Console::WriteLine( UTF8b->GetHashCode() );
   Console::WriteLine( UTF8c->GetHashCode() );
   Console::WriteLine( UTF8d->GetHashCode() );
}

using System;
using System.Text;

class UTF8EncodingExample {
    public static void Main() {
        // Many ways to instantiate a UTF8 encoding.
        UTF8Encoding UTF8a = new UTF8Encoding();
        Encoding UTF8b = Encoding.UTF8;
        Encoding UTF8c = new UTF8Encoding(true, true);
        Encoding UTF8d = new UTF8Encoding(false, false);

        // But not all are the same.
        Console.WriteLine(UTF8a.GetHashCode());
        Console.WriteLine(UTF8b.GetHashCode());
        Console.WriteLine(UTF8c.GetHashCode());
        Console.WriteLine(UTF8d.GetHashCode());
    }
}

Imports System.Text

Class UTF8EncodingExample
    
    Public Shared Sub Main()
        ' Many ways to instantiate a UTF8 encoding.
        Dim UTF8a As New UTF8Encoding()
        Dim UTF8b As Encoding = Encoding.UTF8
        Dim UTF8c = New UTF8Encoding(True, True)
        Dim UTF8d = New UTF8Encoding(False, False)
        
        ' But not all are the same.
        Console.WriteLine(UTF8a.GetHashCode())
        Console.WriteLine(UTF8b.GetHashCode())
        Console.WriteLine(UTF8c.GetHashCode())
        Console.WriteLine(UTF8d.GetHashCode())
    End Sub
