Ejemplos

En el ejemplo siguiente se usa el GetHashCode método para devolver un código hash para UTF8Encoding las instancias. Tenga en cuenta que el código hash devuelto por este método depende del constructor utilizado para crear el UTF8Encoding objeto.

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
End Class
