Sealed Class in C# Programming

In C# programming, a “sealed class” is a powerful construct that plays a crucial role in shaping class hierarchies and promoting code integrity. When a class is marked as sealed, it signals that the class is final, meaning it cannot be extended or inherited by any other class. This deliberate restriction is imposed to enforce a specific design decision, encapsulate implementation details, and ensure a well-defined and controlled class hierarchy.

Sealed Class in C# Programming

Sealed classes are particularly useful in scenarios where the integrity of a class or a set of related classes needs to be maintained without allowing external extensions. By preventing inheritance, sealed classes contribute to creating stable and predictable code structures, enhancing the overall robustness and maintainability of the software.

What is Sealed Class?

In C#, a sealed class is a class that cannot be inherited by other classes. By marking a class as sealed, you explicitly state that it should not serve as a base class for further derivation. This prevents other classes from extending or inheriting from the sealed class.

Here’s a simple example of a sealed class in C#:

using System;

public sealed class SealedExample
{
    public void DisplayMessage()
    {
        Console.WriteLine("This is a sealed class.");
    }
}
