CSHARP.TYPE.ME : Mutable Enumeration (C#)

Summary

An enumeration can be mutated.

Fields should be used to hold the state of the objects. They are not meant to hold temporary data that is not used again after a method completes. In that case, we talk about improper fields, that should rather be replaced by variables local to the methods. Improper fields complicate the code since they make it messy. They cost memory, since they require space for themselves; moreover, if they have reference type, they prevent the garbage collection of the memory reachable from them.
