将 .Net 对象转换为 IronPython、Dynamo 中的另一个 .Net 对象

Question

• the revit API IndependentTag.Create() method requires a Reference object as one of its inputs
• A Reference object is instantiated with a revit Element object
• I have bunch of revit Wall objects which inherit from the Element class
• in C# I can simply say: Reference ref = new Reference(wall as Element);
• clr.Convert does not cast correctly, just returns the object as a Wall again
• ref = Reference(wall) in python gives an exception that the reference cannot be used

Can one cast a .Net object to its parent object in python (iron python)? I am trying to bandage up someone's dynamo/python script and that one object is mucking it up

Answer 1

In C#, if wall is of class Wall and that inherits from Element , there is no need to cast wall to Element . You can just use wall as is. It is already a Wall and therefore also an Element . I would assume the same applies in Python. I suggest you post a code snippet for better understanding.
