Reading Classics-The equality and identity of the Jeffrey Richter of the CLR via C #

"Overriding the considerations of equals"

1. Equals must be reflexive;--x. Equals (x) must be True

2. Equals must be symmetrical;--x. Equals (y) is definitely returned with Y. Equals (x) the same value

3. Equals must be transitive;--x. Equals (Y) returns True, Y.equals (z) returns True, X. Equals (z) must return True

4. Equals must be consistent. The two values that are compared do not change, and the value returned by Equals (true or false) does not change.

5. Allow the type to implement the Equals method of the System.iequatable<t> interface, which allows you to define a type-safe equals method. Typically, the Equals method that you implement should obtain an object parameter so that the type-safe equals method is called internally.

6. Overload the = = and! = operator methods. Typically, these operator methods should be implemented internally to invoke the Equals method of type safety.
