How to edit a sketch of Extrusion?

How to edit a sketch of Extrusion? When I try to replace the CurrArrArray, It told me that "Collection is read-only".

...

Extrusion.Sketch.Profile.Clear();

Extrusion.Sketch.Profile.Append(CurveArray);

...

Can you try this way?

CurveArrArray arrArray = Extrusion.Sketch.Profile;

arrArray.Clear();

arrArray.Append(CurveArray);

Not sure if this helps.

I am trying to accomplish the same thing, and tried Joe.Ye's suggestion however:

CurveArrArray arrArray = Extrusion.Sketch.Profile;

arrArray.Clear();

arrArray.Append(CurveArray);

This also reports back that the array is read only.  Revit 2019.

I am just trying to edit a void extrusions profile by replacing it with a new curve array.

Any help would be greatly appreciated.
