CspKeyContainerInfo.Accessible Eigenschaft

Definition

Namespace:

System.Security.Cryptography

Assembly:

System.Security.Cryptography.dll

Quelle:

CspKeyContainerInfo.NotSupported.cs

Ruft einen Wert ab, der angibt, ob auf einen Schlüssel in einem Schlüsselcontainer zugegriffen werden kann.

public:
 property bool Accessible { bool get(); };

public bool Accessible { get; }

member this.Accessible : bool

Public ReadOnly Property Accessible As Boolean

Eigenschaftswert

Boolean

true, wenn auf den Schlüssel zugegriffen werden kann, andernfalls false.

Ausnahmen

NotSupportedException

Der Schlüsseltyp wird nicht unterstützt.

Beispiele

Im folgenden Codebeispiel wird ein Schlüsselcontainer erstellt und Informationen zu diesem Container abgerufen.
