How to prevent a class can be inherit in C#

Answer:

If you want to prevent a class to create subclass, the class must be sealed. Most of the security classes are sealed.

Sample Code

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    public sealed class TryCatch
    {
        public void SaveEmployee(string empID)
        {

               // few line of code here            
            
        }
    }
}
