Here, we will check a specified class is a sealed class or not using the IsSealed property of Type class.

Program:

The source code to check a specified class is sealed class or not is given below. The given program is compiled and executed successfully on Microsoft Visual Studio.

//C# program to check a specified class is sealed class or not.

using System;
using System.Reflection;

sealed class Sample
{ 
    public static void Print()
    {
        Console.WriteLine("Print() method called");
    }
}

class Program
{
    static void Main()
    {
        Type type = typeof(Sample);

        if (type.IsSealed == true)
        {
            Console.WriteLine("Sample is a sealed class");
        }
        else
        {
            Console.WriteLine("Sample is not a sealed class");
        }
    }
}

Output:

Sample is a sealed class
Press any key to continue . . .

Explanation:

In the above program, we created two classes Sample and Program. The Sample is a sealed class that contains a static Method Print(), and the Program class contains the Main() method. The Main() method is the entry point for the program. Here we check the specified class is a sealed class or not using the IsSealed property of Type class and printed the appropriate message on the console screen.
