Value Types Containing Reference Types

Now that you have a better feeling for the core differences between value types and reference types,

let’s examine a more complex example. Assume you have the following reference (class) type that

maintains an informational string that can be set using a custom constructor:

class ShapeInfo

{

public string infoString;

public ShapeInfo(string info)

{ infoString = info; }

}

Now assume that you want to contain a variable of this class type within a value type named

Rectangle. To allow the caller to set the value of the inner ShapeInfo member variable, you also pro-

vide a custom constructor. Here is the complete definition of the Rectangle type:

struct Rectangle

{
