throw new exception- C#

This post will be in response to my older post about throw exception best practice. where one of user asked that I should include throw new exception.So I thought it will be good idea to write a whole blog post for it. This blog post explains what's wrong with throw new exception.

What’s wrong with throw new exception:

Throw new exception is even worse, It will create a new exception and will erase all the earlier exception data. So it will erase stack trace also.Please go through following code. It’s same earlier post the only difference is throw new exception.

using System;

namespace Oops
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                DevideByZero(10);
            }
            catch (Exception exception)
            {
                throw new Exception
                (string.Format(
                    "Brand new Exception-Old Message:{0}",
                     exception.Message));
            }
        }

        public  static void DevideByZero(int i)
        {
           int j = 0;
           int k = i/j;
           Console.WriteLine(k);
          
        }
    }
}

Now once you run this example. You will get following output as expected.
