Sealed Class with example

Sealed Class:

A sealed class is a class which cannot be inherited. A sealed class cannot be a base class. The modifier abstract cannot be applied to a sealed class. By default, struct (structure) is sealed. It is the last class in hierarchy. To access the members of a sealed class, you must create objects of that class. 
Sealed Class is denoted by the keyword sealed.

Example:

sealed class mySealedClass

{

      int a;

      int b;

}

class mainClass

{

      public static void Main()

      {

            mySealedClass obj = new mySealedClass();

            obj.a = 5;

            obj.b = 7;

            Console.WriteLine("a = {0}, b = {1}", obj.a, obj.b);

      }

}
