Why should I override Equals() and GetHashCode() methods for my value types?
If Equals() and GetHashCode() are not overridden, the implementations of these methods as defined in the parent class ValueType are used. Because these implementations must work for any valuetype, they perform boxing and use reflection to get information about your type. This approach is not only less precise, but also much slower than a dedicated override. Providing a more precise and efficient implementation of Equals() and GetHashCode() for your concrete type will perform much better than the general implementations supplied by ValueType.
