In the “Understanding Reference Types” section, earlier in this chapter, you saw how reference type assignments differ from value type assignments and how assignments are not enough to create a copy of a reference type. You also saw one basic solution to this problem, which involved creating a new instance of a specified reference type and then assigning each property of the target instance with values coming from the original one. But this is not enough, both because it is not complete and because it can be good only with small classes.

To create a complete clone of a reference type, in.NET development, you can take advantage of two techniques: deep copy and shallow copy. Both of these techniques require implementation ...
