Their basic declaration is the same as with any variable, however like methods they should have public static added to the beginning.
Are properties variables?
Properties basically provide the illusion of a “variable” while actually just being a cleverly disguised pair of methods. Note that most properties will use a field to store their value. Properties seldom exist on their own, apart from fields.
What is property C#?
A property is a member that provides a flexible mechanism to read, write, or compute the value of a private field. Properties can be used as if they are public data members, but they are actually special methods called accessors.
