What are Sealed Classes in C#?..

Answer / mukesh kumar

A class which restricts inheritance for security region is
called Sealed class.
Sealed class is the last class in hierarchy that why a
sealed class can be a derived class but can never be a base
class.
To access the members of sealed class we should create the
instance object.

Advantages of sealed class is it restrict the third party
vendor for developing new software by inheriting from our
logic.

Answer / gpriya

A sealed class cannot be inherited. It is an error to use a
sealed class as a base class. Use the sealed modifier in a
class declaration to prevent inheritance of the class.

It is not permitted to use the abstract modifier with a
sealed class.

Structs are implicitly sealed; therefore, they cannot be
inherited.

What are Sealed Classes in C#?..

Answer / saba

Sealed classes are used to restrict the inheritance feature
of object oriented programming. Once a class is defined as
sealed class, this class cannot be inherited.

The following class definition defines a sealed class in C#:

// Sealed class

sealed class SealedClass

{

}

In the following code, I create a sealed class SealedClass
and use it from Class1. If you run this code, it will work
fine. But if you try to derive a class from sealed class,
you will get an error.

using System;

class Class1

{

static void Main(string[] args)

{

SealedClass sealedCls = new SealedClass();

int total = sealedCls.Add(4, 5);

Console.WriteLine("Total = " + total.ToString());

}

}

// Sealed class

sealed class SealedClass

{

public int Add(int x, int y)

{

return x + y;

}

}
