Hi,
Code:
Console.WriteLine("Please Enter your username :");
                    int Counter = 0;
                    s = Console.ReadLine();
                    Counter = Counter + 1;
                    sw.WriteLine(Counter + " " + s);
                    sw.Write(sw.NewLine);
1. Where to put while condition so it can read file and increment the counter?
2. When every time i enter one name it comes out of getusername function and display the menu options again. How to prevent that?

Regards,
