The internal references point to the same object!

As you can see, when you change the value of the informational string using the r2 reference,

the r1 reference displays the same value. By default, when a value type contains other reference

types, assignment results in a copy of the references. In this way, you have two independent struc-

tures, each of which contains a reference pointing to the same object in memory (i.e., a “shallow

copy”). When you want to perform a “deep copy,” where the state of internal references is fully

copied into a new object, one approach is to implement the ICloneable interface (as you will do in

Chapter 9).
