C# Sealed Class Tutorial with Examples
Today, We want to share with you C# Sealed Class Tutorial with Examples.
In this post we will show you Sealed Class in C#, hear for c# – Static and Sealed class differences we will give you demo and example for implement.
In this post, we will learn about Sealed Classes in C# with an example and explanation with an example.
Sealed Class in C#
In this post,we will learn about Sealed Class in C# with an example.I will also review why programming expert use sealed classes in their code and products.
Now in this post, I will explain about Sealed Class in C# with appropriate example.
In C#, the sealed modifier or keyword is used to define a class as sealed. In Visual Basic .NET the NotInheritable keyword serves the purpose of sealed. If a class is derived from a sealed class then the compiler throws an error and mark it as invalid.
Now create Console Application in Visual Studio and write below lines of code in it.
using System;
using System.Collections;
namespace ConsoleDemo
{
class Program
{
static void Main(string[] args)
{
SealedClass sealedCls = new SealedClass();
int total = sealedCls.AddNumber(7, 3);
Console.WriteLine("Sum = " + total.ToString());
Console.ReadLine();
}
}
sealed class SealedClass
{
public int AddNumber(int x, int y)
{
return x + y;
}
}
}
Why Sealed Classes?
The basic intesnsion of a sealed class is to take away the inheritance feature from the user so they cannot derive a class from a sealed class. One of the best usage of sealed classes is when you have a class with static members.
