Ref keyword in c#

Ref is a c# keyword use to for pass argument by reference.So any change in the function or method it will reflect in the variable when it called.


public static string Gamevalue(ref int id)
    string Text = "Next-" + id.ToString();
    id += 2;
    return Text;
static void Main(string[] args)
    int i = 1;
    Console.WriteLine("Previous value :" + i.ToString());
    string test = Getvalue(ref i);
    Console.WriteLine("Current value:" + i.ToString());

Previous value : 1
Current value  :  3

I wish you are happy to use the Ref keyword while you programming on c#. If anything to know about programming language c# please comment. I will make a lesson for you.
