Веб-сервер с изображением с использованием C #

Question

У меня проблема с созданием локального веб-сайта, к которому можно получить доступ с другого компьютера в моей локальной сети

Я хочу передать изображение с картинки и текст с textbox на сайт.

Я использовал код, который нашел в Интернете, но изменил его.

Вот мой код в виде:

using System.Text;
using System.Windows.Forms;

namespace Html_Server
{
    public partial class Form1 : Form
    {
        private string TextToshpw;
        Machine Machine;
        public Form1()
        {
            InitializeComponent();
            TextToshpw = textBox1.Text;
            Machine = new Machine(555, TextToshpw);
        }

        private void button1_Click(object sender, EventArgs e)
        {
          //  Machine.Update();
        }

        private void Form1_Load(object sender, EventArgs e)
        {

            Machine.Start();
        }
    }
}

А вот код, который я нашел с изменениями:
