Overloading operators is generally only useful when you’re building utility types. Strings,

points, rectangles, fractions, and hexagons make good candidates for operator overloading. People,

managers, cars, database connections, and web pages do not. As a rule of thumb, if an overloaded

operator makes it 

harder for the user to understand a type’s functionality, don’t do it. Use this fea-

ture wisely.

Also be aware that even if you do not tend to overload operators for your custom classes,

numerous types in the base class libraries have already done so. For example, the System.Drawing.

dll assembly provides an “official” Point definition that overloads numerous operators. Notice the

operator icon from the Visual Studio 2008 Object Browser (see Figure 12-4).
