public GoObject AddCopy( 
   GoObject obj,
   PointF loc
)

Parameters

obj

loc

Return Value

This creates a singleton collection and calls CopyFromCollection(IGoCollection,Boolean,Boolean,SizeF,GoCopyDictionary) with the appropriate offset. This method is different from Add in that the latter method causes the document to own the object; i.e., the object's GoObject.Layer property is modified to be this document's default layer. But this method does not modify the obj and may add the copy to a different layer, if obj belongs to a layer and CopyFromCollection can find a matching layer in this document.

If you want to make a copy of a GoObject but do not want to add it to a document, you can call GoCopyDictionary.CopyComplete or GoObject.GoObject.Copy.
