What are the differences between a static and a non-static class in C#?

The following is the difference between a static and non-static class −

• Non-static classes can be instantiated, whereas static classes cannot be instantiated i.e. you cannot use the new keyword to create a variable of the class type

• Static classes can only have static methods.

• Non-static classes can have instance method and static methods.

• ou access the members of a static class by using the class name itself

• Static class is sealed.

Example of static class −

Example of non-static class −
