Property Value

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

The individual elements of the property value cannot be null (Nothing in Visual Basic).

Because the UAEventFilter has an implicit conversion from UAAttributeFieldCollection, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use the returned OPC UA attribute field collection (representing the Select clauses of the event filter) in any place where UAEventFilter is expected as input, and the corresponding OPC UA event filter will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the FromUAAttributeFieldCollection static method instead.

This method or property does not throw any exceptions, aside from execution exceptions such as System.Threading.ThreadAbortException or System.OutOfMemoryException.
