abstract class is used for declaring the abstract methods just . You can't create a object of abstract class. In order to define and use abstract methods you need to inherit from abstract class in some other class and then use override to provide definition for abstract methods . If you are looking for implementation in c# you can check following article . https://www.google.com/url?sa=t&source=web&rct=j&url=https://www.w3schools.com/cs/cs_abstract.asp&ved=2ahUKEwiS2-HEpo7wAhVJWX0KHSeiDscQFjAAegQIAxAC&usg=AOvVaw1H34F_lxVtTBxv2OSNVJwO&cshid=1618972561386
