C# - Members of a Class

A class can have following members inside it

Fields

Fields allow classes and structures to encapsulate data. A field can be given an initial value. Fields are initialized automatically before the constructor for the object instance is called. A field initializer cannot refer to other fields. 

Generally it is not recommended to use public fields. You should mark them as private and expose them via. Properties.

Properties

Is a flexible mechanism to read, write or compute value of a private field. Properties are actually special methods called accessors.

introduced in C# 3.0, Auto implemented properties make property declaration more easy. When you create a auto implemented property, compiler creates a private, anonymous backing field that can only be accessed through property's get and set accessors. To give auto implemented properties a default value you have to do it in the constructor but starting from C# 6.0 you can do it more easily.

fields, constants, properties, methods, constructors, destructors, events, indexers, operators as well as nested types
