Syntax
'Declaration
Public Overridable ReadOnly Property CodePage As Integer
'Usage
Dim instance As Encoding
Dim value As Integer
value = instance.CodePage
public virtual int CodePage { get; }

Der Codepagebezeichner der aktuellen Encoding-Klasse.
Beispiel
Im folgenden Codebeispiel werden die verschiedenen Namen für jede Codierung abgerufen und die Codierungen angezeigt, bei denen sich ein Name oder mehrere Namen von EncodingInfo.Name unterscheiden. EncodingName wird angezeigt, aber nicht für den Vergleich verwendet.
