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.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.

Remarks

The product URI is used:

In the application instance certificate, when the component creates it.
In the client description, when the OPC-UA session is created.

When this object is used to override properties of another application manifest, an empty value in this property keeps the original value. A non-empty value in this property overrides the original value. Use "#" to set the value back to an empty string.

In order to obtain or modify this parameter, access the OpcLabs.EasyOpc.UA.Engine.UAClientServerApplicationParameters.ApplicationManifest property of OpcLabs.EasyOpc.UA.Application.EasyUAApplicationCore.ApplicationParameters property of static EasyUAApplication.Instance.
