This operation is equivalent to adding a Point to a Vector.
Note that calling the Offset method will only have an effect if you can change the X and Y properties directly. Because Point is a value type, if you reference a Point 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 or Y 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 Point that is referenced as a property or indexer, create a new Point, modify its fields, and then assign the Point back to the property or indexer.
private Point offsetExample()
Point pointResult = new Point(10, 5);
// Offset Point X value by 20 and Y value by 30. // point1 is now equal to (30,35)
