14.2. Implement a Cloneable Type
You need to create a custom type that provides a simple mechanism for programmers to create copies of type instances.
Implement the System.ICloneable interface.
How It Works
When you assign one value type to another, you create a copy of the value. No link exists between the two values—a change to one will not affect the other. However, when you assign one reference type to another (excluding strings, which receive special treatment by the runtime), you do not create a new copy of the reference type. Instead, both reference types refer to the same object, and changes to the value of the object are reflected in both references. To create a true copy of a reference type, you must clone the object ...
