如何在C#中找到字符的键码？

using System;
using System.Windows.Forms;

public class KeyPressExample : Form
{
    public KeyPressExample()
    {
        KeyPress += KeyPressExample_KeyPress;
    }

    private void KeyPressExample_KeyPress(object sender, KeyPressEventArgs e)
    {
        Console.WriteLine("Character: " + e.KeyChar);
        Console.WriteLine("Key code: " + (int)e.KeyChar);
    }

    public static void Main()
    {
        Application.Run(new KeyPressExample());
    }
}
