| Introduction |
Anyone planning on writing code in C# should understand the
data types available. Before diving into this, however, it is important to
understand value types and reference types. This article is designed to give
you a quick understanding of these. This article is not meant for people who
already understand the difference between these two categories of data types.
Knowing this information will give you a much better understanding of how data
is stored and how to correctly interact with this data in C#. As you read on, I
explain the difference between these two classifications of data types, and I
explain how these differences impact you as a C# developer.

Good articel. You have to be careful with your example in the chapter 'Reference Assignment' thought. The assignment in the example works exact the way it is illustrated, but the text after the figure is only true for reference types that aren't strings. Strings are implemented as immutable and will automatically created a new instance if they are changed. So a change of 'myName' would create an independent instance with 'myName' pointing to it and authorName would keep its pointer to the old instance and so its value would remain unchanged.
