❔ Windows Forms different controls but same event doing different code?

private void OnSecondsChange(object sender, EventArgs e)
{
    textBoxUpTime.Text += $"{sender} fired out"; // somehow distinguish the sender and behave differently later in the code
}

private void OnSecondsChange(object sender, EventArgs e)
{
    textBoxUpTime.Text += $"{sender} fired out"; // somehow distinguish the sender and behave differently later in the code
}

I was wondering if there is a way I can link one method to multiple controls events (such as OnClick) and depending on which element fired the event do something different? For example there are 4 buttons and each has the same OnClick event method linked but I want the code for each button behave slightly different

Write to file not working (StreamWriter)

using System;
using System.Numerics;
using System.Text;
using System.IO;
namespace Username
{
    class Program
    {
        static void Main()
        {
            bool end = false;
            string filePath = @"C:\Users\Administrator\Desktop\HEXes.txt";

            StreamWriter hap = new(filePath, false, Encoding.Unicode);
            
            hap.WriteLine($"{F:N0} is {F:X}"); // there are variables I didn't mention, I just wanted to show here I write to file

            hap.Close();
            Console.ForegroundColor = ConsoleColor.Yellow;
            Console.Write("\nPress any key to continue...");
            Console.ReadKey();
        }
    }
}

using System;
using System.Numerics;
using System.Text;
using System.IO;
namespace Username
{
    class Program
    {
        static void Main()
        {
            bool end = false;
            string filePath = @"C:\Users\Administrator\Desktop\HEXes.txt";

            StreamWriter hap = new(filePath, false, Encoding.Unicode);
            
            hap.WriteLine($"{F:N0} is {F:X}"); // there are variables I didn't mention, I just wanted to show here I write to file

            hap.Close();
            Console.ForegroundColor = ConsoleColor.Yellow;
            Console.Write("\nPress any key to continue...");
            Console.ReadKey();
        }
    }
}

~~It creates HEXes.txt but the file is empty~~ Never mind, my silly mistake. Closing.

delegate inside our outside class?

delegate void ADelegate(); // here?
public class PlayerShip : MonoBehaviour
{
    delegate void ADelegate(); // or here?
    event ADelegate DelegateHandler;
}

delegate void ADelegate(); // here?
public class PlayerShip : MonoBehaviour
{
    delegate void ADelegate(); // or here?
    event ADelegate DelegateHandler;
}

Should I create a delegate inside or outside a class? Is there a difference?

Hexadecimal format specifier not working

for(int X = 1 ; X <= 5 ; X++)
{
    var F = Math.Pow(63, X);
    Console.WriteLine($"{F:X}");
}

for(int X = 1 ; X <= 5 ; X++)
{
    var F = Math.Pow(63, X);
    Console.WriteLine($"{F:X}");
}

For some reason this is not working and I receive an error: FormatException: Format specifier was invalid.
