This post will be in response to my older post throw vs. throw(ex) best practice and difference- c# comment that I should include 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.
