PackageDigitalSignatureManager.VerifySignatures(Boolean) Methode

Definition

Überprüft die Signaturen für alle signierten Teile im Paket.

public:
 System::IO::Packaging::VerifyResult VerifySignatures(bool exitOnFailure);
public System.IO.Packaging.VerifyResult VerifySignatures (bool exitOnFailure);
member this.VerifySignatures : bool -> System.IO.Packaging.VerifyResult
Public Function VerifySignatures (exitOnFailure As Boolean) As VerifyResult

Parameter

exitOnFailure
Boolean

true, wenn beim ersten Fehler beendet werden soll, andernfalls false, damit alle Signaturen überprüft werden.

Gibt zurück

Success (Wert 0), wenn alle Signaturen erfolgreich überprüft wurden, andernfalls eine Enumeration, die den Fehler kennzeichnet.

Beispiele

Das folgende Beispiel zeigt, wie Sie diese Methode verwenden, um alle signierten Teile innerhalb eines Pakets zu überprüfen.

{
    if (package == null)
        throw new ArgumentNullException("ValidateSignatures(package)");

        new PackageDigitalSignatureManager(package);

    // Check to see if the package contains any signatures.

Hinweise

Diese Methode überprüft nur die digitalen Signaturen. Die zugehörigen X.509-Zertifikate werden nicht überprüft. Die VerifyCertificate -Methode kann verwendet werden, um die X.509-Zertifikate zu überprüfen.
