AppDomain.DynamicDirectory-Eigenschaft

  • Artikel

Ruft das Verzeichnis ab, das der Assemblyresolver für die Suche nach dynamisch erstellten Assemblys verwendet hat.

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

Syntax

'Declaration
Public ReadOnly Property DynamicDirectory As String
'Usage
Dim instance As AppDomain
Dim value As String

value = instance.DynamicDirectory

public string DynamicDirectory { get; }

public:
virtual property String^ DynamicDirectory {

public final function get DynamicDirectory () : String

Eigenschaftenwert

Ruft das Verzeichnis ab, das der Assemblyresolver für die Suche nach dynamisch erstellten Assemblys verwendet.

Ausnahmen

Ausnahmetyp Bedingung

AppDomainUnloadedException

Es wird versucht, die Operationen für eine entladene Anwendungsdomäne auszuführen.

Hinweise

Diese Eigenschaft ist nur dann verfügbar, wenn versucht wurde, eine Assembly in diese Domäne zu laden.
