Puneet Kankar · Answer

Hi Sanjit, Please check below links. There are two primary reasons for sealing a class or a method. First, and the most important one (probably) is that you disallow inheritance on the type or method in question. This can be important in some cases. Second reason is that the compiler can apply optimizations it otherwise could not have done. https://stackoverflow.com/questions/23034919/why-use-sealed-on-a-method-or-property-whenever-the-current-class-is-a-subclass https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/sealed https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/sealed https://www.youtube.com/watch?v=LypTOnfkfvA&t=14s

Sealed class is used to stop a class to be inherited. Sealed method is implemented so that no other class can overthrow it and implement its own method. The main purpose of the sealed class is to withdraw the inheritance attribute from the user so that they can't attain a class from a sealed class.

Amit Kumar · Answer

Hi, Sealed is a keyword which is used to stop inheriting the particular class from other classes and we can also prevent overriding the particular properties or methods based on our requirements. Generally, when we create a particular class we can inherit all the properties and methods in any class. In case, if you want to restrict an access of defined class and its members, then by using sealed keyword we can prevent other classes from inheriting the defined class.
