AssemblyName.KeyPair Eigenschap
Definitie
Belangrijk
Bepaalde informatie heeft betrekking op een voorlopige productversie die aanzienlijk kan worden gewijzigd voordat deze wordt uitgebracht. Microsoft biedt geen enkele expliciete of impliciete garanties met betrekking tot de informatie die hier wordt verstrekt.
Hiermee haalt u het openbare en persoonlijke cryptografische sleutelpaar op dat wordt gebruikt voor het maken van een sterke naamhandtekening voor de assembly.
public:
property System::Reflection::StrongNameKeyPair ^ KeyPair { System::Reflection::StrongNameKeyPair ^ get(); void set(System::Reflection::StrongNameKeyPair ^ value); };
public System.Reflection.StrongNameKeyPair KeyPair { get; set; }
member this.KeyPair : System.Reflection.StrongNameKeyPair with get, set
Public Property KeyPair As StrongNameKeyPair
Waarde van eigenschap
Het openbare en persoonlijke cryptografische sleutelpaar dat moet worden gebruikt om een sterke naam voor de assembly te maken.
Uitzonderingen
.NET 6+ alleen: in alle gevallen.
Voorbeelden
In het volgende voorbeeld wordt een dynamische assembly verzonden en opgeslagen in de huidige map. Wanneer de assembly wordt gemaakt, wordt de KeyPair eigenschap gebruikt om de openbare en persoonlijke cryptografische sleutels van de assembly in te stellen.

Opmerkingen
Wanneer de runtime een assembly laadt, wordt de KeyPair eigenschap niet ingesteld. De getter voor de eigenschap is alleen nuttig als de gebruiker de eigenschap instelt voordat het AssemblyName object wordt gebruikt om een dynamische assembly te maken en vervolgens het sleutelpaar wil ophalen.
