Rect3D.Offset Method (Vector3D)
Assembly: PresentationCore (in PresentationCore.dll)
Note that calling the Offset method will only have an effect if you can change the X, Y, and Z properties directly. Because Rect3D is a value type, if you reference a Rect3D object by using a property or indexer, you get a copy of the object, not a reference to the object. If you attempt to change X, Y, or Z on a property or indexer reference, a compiler error occurs. Similarly, calling Offset on the property or indexer will not change the underlying object. If you want to change the value of a Rect3D that is referenced as a property or indexer, create a new Rect3D, modify its fields, and then assign the Rect3D back to the property or indexer.
