我有一个问题,使本地网站,可以从其他计算机访问我的本地网络

我想将picturebox中的图像和
textbox
中的文本传递到网站中

我使用了我在网上找到的代码,但我已经修改了它

以下是我在表格中的代码:

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();
        }
    }
}
下面是我发现的经过修改的代码:
