C# 使用C语言的带图像的Web服务器#
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C# 使用C语言的带图像的Web服务器#,c#,html,image,text,webserver,C#,Html,Image,Text,Webserver,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 TextTosh
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:
