Replace a string in a string in C#
We can replace a string that is there in another string as below: 

using System;
using System.IO;
using System.Text;

namespace forgetCode
{
    class program1
    {
        static void Main(string[] args)
        {
            string baseString = "Forget code";

            string newString = baseString.Replace("get","getting");

            Console.WriteLine(newString);

        }
   
    }
}


Output:
Forgetting code
