ANSWER
Thanks to those who answered. Here is a synthetic code based on a few answers :

Console.WriteLine("Choose user settings to setup");
Console.WriteLine("User setting1: press 1");
Console.WriteLine("User setting2: press 2");

int code = int.Parse(line);
swicth(code) 
{
   case 1: 
    Settings.Default.MyProperty = line ;
    Settings.Default.Save();
    break;
