C# SealedC# sealed keyword applies restrictions on the class and method. If you create a sealed class, it cannot be derived. If you create a sealed method, it cannot be overridden. Note: Structs are implicitly sealed therefore they can't be inherited.C# Sealed classC# sealed class cannot be derived by any class. Let's see an example of sealed class in C#. Output: Compile Time Error: 'Dog': cannot derive from sealed type 'Animal' C# Sealed methodThe sealed method in C# cannot be overridden further. It must be used with override keyword in method. Let's see an example of sealed method in C#. Output: Compile Time Error: 'BabyDog.run()': cannot override inherited member 'Dog.run()' because it is sealed Note: Local variables can't be sealed.Output: Compile Time Error: Invalid expression term 'sealed'
