Parameters

application

The OPC UA client/server application object that will perform the operation.

In client applications, this is typically obtained by calling System.IServiceProvider.GetService(System.Type) on the OpcLabs.EasyOpc.UA.IEasyUAClient (EasyUAClient object) with the type of OpcLabs.EasyOpc.UA.Application.IEasyUAClientServerApplication as an argument.

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

arguments

The arguments describing how the certificate should be obtained.

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

Return Value

This method never returns null (Nothing in Visual Basic).

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.OperationCanceledException	An operation that the thread was execution has been cancelled.
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.OperationCanceledException An operation that the thread was execution has been cancelled.

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.

Remarks

This is an extension method (info: C#, VB.NET). In languages that have support for extensions methods (such as C# and VB.NET), you can use the extension method as if it were a regular method on the object that is its first parameter. In other languages (such as with Python.NET), you will call the extension as a static method, and pass it the object on which it acts as its first parameter.

Requirements

Target Platforms: .NET Framework: Windows 10 (selected versions), Windows 11 (selected versions), Windows Server 2016, Windows Server 2022; .NET: Linux, macOS, Microsoft Windows
