Structures and Common Language Specification

The Common Language Specification (CLS) has established specific rules for structures. If you want your structure to be CLS-compliant, you need to overload the equality and inequality operators and redefine the behavior of the Equals and GetHashCode methods inherited from Object. Listing 11.1 shows an example of a CLS-compliant structure.
