Property Value

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

Because the DAPropertyId has an implicit conversion to System.Int64 and DAPropertyIds, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use the return value in place of a System.Int64 (representing the numerical value of the property Id), or in place a DAPropertyIds enumeration value. When the implicit conversion operators are not supported (such as with Python.NET), you can use the ToInt64 or ToDAPropertyIds static method instead.

Also, because there is an implicit conversion from DAPropertyId to DAPropertyDescriptor, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use the returned DAPropertyId in any place where DAPropertyDescriptor is expected as input, and the corresponding OPC DA property descriptor will be constructed automatically from the OPC DA property Id. When the implicit conversion operators are not supported (such as with Python.NET), you can use the FromDAPropertyId static method instead.

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