CannotUnloadAppDomainException-Konstruktor ()

Initialisiert eine neue Instanz der CannotUnloadAppDomainException-Klasse.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

Syntax

'Declaration
Public Sub New
'Usage
Dim instance As New CannotUnloadAppDomainException

public CannotUnloadAppDomainException ()

public:
CannotUnloadAppDomainException ()

public CannotUnloadAppDomainException ()

public function CannotUnloadAppDomainException ()

Hinweise

Dieser Konstruktor initialisiert die Message-Eigenschaft der neuen Instanz mit einer vom System gelieferten Meldung, die den Fehler beschreibt, z. B. "Fehler beim Entladen der Anwendungsdomäne." Diese Meldung berücksichtigt die aktuelle Systemkultur.

In der folgenden Tabelle werden die anfänglichen Eigenschaftenwerte für eine Instanz von CannotUnloadAppDomainException aufgeführt.
