CheckRevocationStatus Method (EasyUACertificateManagementClientCore)

The endpoint descriptor for the Global Discovery Server used to perform the revocation status check.

Because the OpcLabs.EasyOpc.UA.UAEndpointDescriptor has implicit conversions from System.String and System.Uri, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a string (representing the endpoint URL, or a so-called OPC UA endpoint descriptor string), or a System.Uri object, in place of this parameter, and the corresponding endpoint descriptor will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the OpcLabs.EasyOpc.UA.UAEndpointDescriptor.FromString or OpcLabs.EasyOpc.UA.UAEndpointDescriptor.FromUri static method instead.

If you are using OPC Wizard (for server development), an implicit conversion from OpcLabs.EasyOpc.UA.EasyUAServerCore can be used in the same way to simply pass the server object in place of this parameter, which will use its OpcLabs.EasyOpc.UA.EasyUAServerCore.EffectiveServerDescriptor property for the connection.

The value of this parameter cannot be null (Nothing in Visual Basic).

Checks the revocation status of the specified certificate using the provided Global Discovery Server (GDS) endpoint descriptor.

Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
Public Sub CheckRevocationStatus( _
   ByVal gdsEndpointDescriptor As UAEndpointDescriptor, _
   ByVal certificate() As Byte, _
   ByRef certificateStatus As UAStatusCode, _
   ByRef validityTime As Date _
)

'Usage
 
Dim instance As EasyUACertificateManagementClientCore
Dim gdsEndpointDescriptor As UAEndpointDescriptor
Dim certificate() As Byte
Dim certificateStatus As UAStatusCode
Dim validityTime As Date
 
instance.CheckRevocationStatus(gdsEndpointDescriptor, certificate, certificateStatus, validityTime)

public void CheckRevocationStatus( 
   UAEndpointDescriptor gdsEndpointDescriptor,
   byte[] certificate,
   out UAStatusCode certificateStatus,
   out DateTime validityTime
)

public:
void CheckRevocationStatus( 
   UAEndpointDescriptor^ gdsEndpointDescriptor,
   array<byte>^ certificate,
   [Out] UAStatusCode^ certificateStatus,
   [Out] DateTime validityTime
)

Parameters

gdsEndpointDescriptor

The endpoint descriptor for the Global Discovery Server used to perform the revocation status check.

The value of this parameter cannot be null (Nothing in Visual Basic).

certificate

The certificate, as a byte array (DER encoded form), whose revocation status is to be checked.

The value of this parameter cannot be null (Nothing in Visual Basic).

certificateStatus

When this method returns, contains the status code indicating the revocation status of the certificate. The first error encountered when validating the certificate is returned.

The value of this parameter cannot be null (Nothing in Visual Basic).

validityTime

When this method returns, contains the time when the result expires and should be rechecked. Contains System.DateTime.MinValue when the validity time is unknown.

Exceptions

Exception Description

Exception	Description
System.ArgumentNullException	A `null` reference (`Nothing` in Visual Basic) is passed to a method that does not accept it as a valid argument. This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception.
System.ObjectDisposedException	An operation was performed on a disposed object.
OpcLabs.EasyOpc.UA.OperationModel.UAException	The OPC UA operation has failed. This operation exception in uniformly used to allow common handling of various kinds of errors. The System.Exception.InnerException always contains information about the actual error cause. This is an operation error that depends on factors external to your program, and thus cannot be always avoided. Your code must handle it appropriately.

System.ObjectDisposedException An operation was performed on a disposed object.
