Prevent a class from being inherited

Hi,

We can Prevent a Class from Being inherited by using Sealed Keyword. 

@Satyapriya is Correct, that Sealed Classes can not be a Base Class.

Added to that, Also Its obvious that Sealed Class can not be an abstract class.










Thank You

Hi Amit,

You can prevent your class being derived using sealed 
keyword.

But you can't use that class as base class once you make 
that sealed.


Thanks

Just add the 'sealed' modifier to a class's declaration so that it cannot be inherited from:

public sealed class MyClass
{
   // code
}

Notice also that a 'static class' is implicitly sealed, though it's an error to add the sealed modifier to it.
