Viktigt
En del information gäller för förhandsversionen av en produkt och kan komma att ändras avsevärt innan produkten blir allmänt tillgänglig. Microsoft lämnar inga garantier, uttryckliga eller underförstådda, avseende informationen som visas här.
Öppnar ett X.509-certifikatarkiv eller skapar ett nytt arkiv, beroende på OpenFlags flagginställningar.
public:
void Open(System::Security::Cryptography::X509Certificates::OpenFlags flags);
public void Open(System.Security.Cryptography.X509Certificates.OpenFlags flags);
member this.Open : System.Security.Cryptography.X509Certificates.OpenFlags -> unit
Public Sub Open (flags As OpenFlags)
Parametrar
- flags
- OpenFlags
En bitvis kombination av uppräkningsvärden som anger hur du öppnar X.509-certifikatarkivet.
Undantag
Det går inte att öppna arkivet på begäran.
Anroparen har inte den behörighet som krävs.
Arkivet innehåller ogiltiga värden.
Exempel
Följande kodexempel öppnar ett X.509-certifikatarkiv, lägger till och tar bort certifikat och stänger sedan arkivet. Det förutsätter att du har tre certifikat att lägga till och ta bort från ett lokalt arkiv.

Kommentarer
Använd den här metoden för att öppna ett befintligt X.509-arkiv. Observera att du måste ha ytterligare behörigheter, som anges av StorePermissionFlags, för att räkna upp certifikaten i arkivet. Du kan skapa en ny butik genom att skicka ett butiksnamn som inte finns till klasskonstruktorn och sedan använda någon av flaggorna OpenFlags förutom OpenExistingOnly.
