Property Value
The value of this property cannot be null
(Nothing
in Visual Basic).
Because the OpcLabs.EasyOpc.UA.PubSub.Configuration.UAPubSubConnectionElement has an implicit conversion to OpcLabs.EasyOpc.UA.PubSub.UAPubSubConnectionDescriptor, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use the returned OpcLabs.EasyOpc.UA.PubSub.Configuration.UAPubSubConnectionElement (from PubSub configuration) in any place where OpcLabs.EasyOpc.UA.PubSub.UAPubSubConnectionDescriptor is expected as input, and the corresponding OPC UA PubSub connection descriptor will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can convert a OpcLabs.EasyOpc.UA.PubSub.Configuration.UAPubSubConnectionElement to OpcLabs.EasyOpc.UA.PubSub.UAPubSubConnectionDescriptor using the ToUAPubSubConnectionDescriptor static method instead.
