Moving position of child gameobject

So I have object A which has a child object B. I want to move the child object B to the position of another object C. I still want to keep object B as a child of object A. I tired changing localposition but that is only relative to the parent object.

 

You can set the regular position. It will remain as a child.

objectB.position = objectC.position;

 

I tried that but the object is no where near the target position.

EDIT: Oh I figured it out. The position was not correct because I was scaling the parent gameobject.

 

You can try this: objectB.position = parentTransform.InverseTransformPoint(objectC.position);

That will convert the objectC.position into the local space for the parentTransform, and then assign it to objectB
