}

Now, the comparison inside Main is much more efficient, since the value doesn’t need to be

boxed. The compiler chooses the closest match of the two overloads, which, of course, is the

strongly typed overload of Equals that accepts a ComplexNumber rather than a generic object type.

Internally, the Object.Equals override delegates to the type-safe version of Equals after it checks the

type of the object and unboxes it. It’s important to note that the Object.Equals override first checks

the type to see if it ...
