11.2.2 test structure is equal

In C #, testing for the equality of complex data structures can be tricky. If we construct a new object with the same properties and use the = = operator to compare two objects, the result is probably false, because we are comparing two different instances.

In C #, the = = operator can be overloaded and object.equals can be overridden, but is typically used only for value types or non-volatile data structures. When comparing two different instances of a mutable type, it is important to recognize the difference between the two, because the data can be changed later, and conversely, if it is two immutable types that store the same values, we can think of them as equal because the data will not change in the future, so two objects are always equal.
