  • Answered by AI
  • Q8. Sealed virtual static new keyword use
  • Ans. 

    Sealed virtual static new keywords are used in C# to control inheritance and method hiding.

    • Sealed keyword prevents a class from being inherited.

    • Virtual keyword allows a method to be overridden in derived classes.

    • Static keyword makes a member of a class accessible without creating an instance of the class.

    • New keyword hides a method from the base class in the derived class.
