Descriptor to be copied from.

Because the UADataSetFieldDescriptor has implicit conversions from System.Guid and System.String, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a GUID (representing the dataset field Id), or a string (representing the name of the dataset field) in place of this parameter, and the corresponding OPC UA dataset field descriptor will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the FromGuid or FromString static method instead.

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

Initializes a new copy of the object.
