  14. Static • Static classes and class members are used to create data and functions that can be accessed without creating an instance of the class • A class can be declared static, indicating that it contains only static members • Use a static class to contain methods that are not associated with a particular object.

  15. Static • For example, it is a common requirement to create a set of methods that do not act on instance data and are not associated to a specific object in your code. • You could use a static class to hold those methods. • The main features of a static class are: • They only contain static members. • They cannot be instantiated. • They are sealed. • They cannot contain Instance Constructors (C# Programming Guide).
