Encoding.HeaderName-Eigenschaft
Beim Überschreiben in einer abgeleiteten Klasse wird ein Name für die aktuelle Codierung abgerufen, die mit den Body-Tags des E-Mail-Agenten verwendet werden kann.
Namespace: System.Text
Assembly: mscorlib (in mscorlib.dll)
Syntax
'Declaration
Public Overridable ReadOnly Property HeaderName As String
'Usage
Dim instance As Encoding
Dim value As String
value = instance.HeaderName
public virtual string HeaderName { get; }
public:
virtual property String^ HeaderName {
String^ get ();
}
/** @property */
public String get_HeaderName ()
public function get HeaderName () : String
Eigenschaftenwert
Der Name der aktuellen Encoding-Klasse, die mit den Header-Tags des E-Mail-Agenten verwendet werden kann. - oder - Eine leere Zeichenfolge (""), wenn die aktuelle Encoding nicht verwendet werden kann.
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.
