How can I read file line. For example I create file settings.dat and i want to store two lines in it, color id, and username. How do i need to do. I tried to google but it was not worth it.

So i have made program that changes username nick in the main menu, but it wont work, here is the code

public void rUsername() 
    {
        string uInput;
        Console.WriteLine("Rename Your Username: ");
        uInput = Console.ReadLine();
        username = uInput;
        Console.Clear();
        Console.WriteLine("You changed your username succesfully! Press Enter To Continue...");
        Console.ReadLine();
        Console.Clear();
        initOptions();
    }

btw in class Options i have variable public string username; So what i want to do is just from this function pass it to the username that is in class, why it is not working (No Errors  btw)

For example I have this code:

Console.Write("Write Your First Number: ");
                num1 = int.Parse(Console.ReadLine()); // If i write here 6/2 or just s,y program frozes and exits. How To Handle that?
                Console.Write("Write Your Operand: ");
                operand = Console.ReadLine(); // If i write here 6/2 or just s,y program frozes and exits. How To handle that
                Console.Write("Write Your Second Number: ");
                num2 = int.Parse(Console.ReadLine()); // If i write here 6/2 or just s,y program frozes and exits. How To Handle That?
                switch (operand) 
                {
                    case "+":
                        answer = num1 + num2;
                        break;
                    case "-":
                        answer = num1 - num2;
                        break;
                    case "*":
                        answer = num1 * num2;
                        break;
                    case "/":
                        answer = num1 / num2;
                        break;
                    default:
                        Console.Clear();
                        Console.WriteLine("You entered wrong operand. Press Any Key To Continue...");
                        Console.ReadLine();
                        Console.Clear();
                        Calc();
                        break;
                }

How can i handle this if switch default is not working? It's just frozes. I just want to make Console.WriteLine("You entered wrong key, try again");

I have a question, what games to create first in console?

I know that first one is Guessing numbers Please tell me more of them
