在 C# WinForm 中将 int 转换为 Hex [重复]

Question

所以我的课堂作业是让我们自己的算法不使用将 int 转换为十六进制的内置函数，并且在我的一生中它不会遵守。

我们文本中的示例将 24032 转换为 0x5DE0，但我得到的输出是 3210。

这是我的代码

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    List<string> errorList = new List<string>();
    List<int> hexList = new List<int>();
    string intInput = "";
    string msgOutput = "";

    private void btn_Hex_Click(object sender, EventArgs e)
    {
        intInput = box_Int.Text;
        int toHexFunc = Validator(intInput);
        ToHex(toHexFunc);
    }

    public void ToHex(int fromHexBtn)
    {
        int n = fromHexBtn;
        char[] hexNum = new char[100];
        int i = 0;
        while (n != 0)
        {
            int iterTemp = n % 16;

            // using ASCII table from https://www.dotnetperls.com/ascii-table
            if (iterTemp < 10)
            {
                hexNum[i] = (char)(iterTemp + 48);
                i++;
            }
            else
            {
                hexNum[i] = (char)(iterTemp + 55);
                i++;
            }

            n = n / 16;
        }

        for (int j = i - 1; j >= 0; j--)
        {
            hexList.Add(j);
        }

        msgOutput = String.Join("", hexList);
        lbl_Message.Text = msgOutput;

        
    }
}

基于此https://www.permadi.com/tutorial/numDecToHex/

class Program
{
    static void Main(string[] args)
    {
       var characters = "0123456789ABCDEF";

       int number = 24032;

       var hexidecimal = "";

       while (number > 0)
       {
          var remainder = number % 16;
          var res = Math.Abs(number / 16);

          hexidecimal = characters[remainder] + hexidecimal;

          number = res;
        }

        hexidecimal = "0x" + hexidecimal;

        WriteLine(hexadecimal);
   }
}
