Cant methods do ReadKey() and ReadLine() by their own or am i forced to use parameters

I can use parameters but i am making a looped arrow key menu so it would not be optimal

sure you can call Console.ReadLine() pretty much anywhere. Is it a good idea to do so? Not always. if your program is only ever gonna be a console app, and you dont want a centralized way to change potential styling etc, then its fine

```cs code ```

the start and end tags must be on new lines

cs                            
using ClassFile;

while (true)
{   
    Console.Clear();
    
     ClassFile.Class.VisaMeny();
  
}

cs                            
using ClassFile;

while (true)
{   
    Console.Clear();
    
     ClassFile.Class.VisaMeny();
  
}

this is the main

So close lol

namespace ClassFile;

public class Class

        string punkt = "*";
        
        int val = 1; 

        Console.WriteLine($"{(val == 1 ? punkt : "  ")} Val (1) ");
        Console.WriteLine($"{(val == 2 ? punkt : "  ")} Val (2) ");
        Console.WriteLine($"{(val == 3 ? punkt : "  ")} Val (3) ");

        ConsoleKeyInfo key;
        key = Console.ReadKey();
    
        switch (key.Key)
        {

                break;

        }

        switch (val)
        {
            case >3:
                val = 1;
                break;
        
            case <1:

                break;
        }   


    } 
}

        }

        switch (val)
        {
            case >3:
                val = 1;
                break;
        
            case <1:
                val = 3;
                break;
        }   


    } 
}

they are on seperate files

Angius•3mo ago

Yeah, and what is the issue? The code seems fine as it is

HD-Fr0sT•3mo ago

when i press the arrow the menu dosent budge seems like the method dosent really listen to readkey i would really like to not use parameters

Pobiega•3mo ago

you dont need to. use a breakpoint and the debugger to figure out what is going wrong its not the Console.ReadKey()

HD-Fr0sT•3mo ago

is it because im not looping the logic inside the method? if yes (slaps face) if no (slaps face twice)

Pobiega•3mo ago

use the debugger check what value your key variable has after you press an arrow key.

HD-Fr0sT•3mo ago

did it

Pobiega•3mo ago

mhm? and what value did it reveal?

HD-Fr0sT•3mo ago

short story it works but i just needed a loop and clear to make it work as i intented

using  ClassFile;

while (true)
{   
    Console.Clear();
     ClassFile.Class.VisaMeny();
  
}

using  ClassFile;

while (true)
{   
    Console.Clear();
     ClassFile.Class.VisaMeny();
  
}

namespace ClassFile;

public class Class
{
    public static int VisaMeny()
    {
    
        string punkt = "*";
        
        int val = 1; 

        while (true)
        {
            Console.Clear();
            Console.WriteLine($"{(val == 1 ? punkt : "  ")} Val (1) ");
            Console.WriteLine($"{(val == 2 ? punkt : "  ")} Val (2) ");
            Console.WriteLine($"{(val == 3 ? punkt : "  ")} Val (3) ");

            ConsoleKeyInfo key;
            key = Console.ReadKey();

            int vald;
        
            switch (key.Key)
            {
                case ConsoleKey.DownArrow:
