一、创建Web页面浏览器

// WebBrowser

// 在“网址”文本框中输入要浏览的网页地址，
// 按Enter键或单击“转到”按钮，即可浏览指定的网页。

1.类

// 聊天室，解决方案下建立的公共类库
using System.Net.Sockets;
using System.Net;
using System.Text;
using System;
using System.Windows;
using System.Windows.Forms;namespace StartListener
{public class Class1{public const int port = 11000;public void StartListener(){UdpClient udpclient = new UdpClient(port);                  //设置端口号IPEndPoint ipendpoint = new IPEndPoint(IPAddress.Any, port);//将网络端点表示为IP地址和端口号try{while (true){byte[] bytes = udpclient.Receive(ref ipendpoint);string strlP = "信息来自" + ipendpoint.Address.ToString();string strlnfo = Encoding.GetEncoding("gb2312").GetString(bytes, 0, bytes.Length);MessageBox.Show(strlnfo, strlP);}}catch (Exception e){MessageBox.Show(e.ToString());}finally{udpclient.Close();}}public static string Send(string strServer, string strContent){Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);IPAddress ipaddress = IPAddress.Parse(strServer);   //将输入的字符串转换为IP地址  byte[] btContent = Encoding.GetEncoding("gb2312").GetBytes(strContent); //将发送的内容存储到byte数组中IPEndPoint ipendpoint = new IPEndPoint(ipaddress, 11000);socket.SendTo(btContent, ipendpoint);socket.Close();return "发送成功";}}
}

2.服务器端

// 服务器端，要增加对公共类的引用
using StartListener;
using System;
using System.Windows.Forms;namespace ChatServer
{public partial class Form1 : Form{readonly Class1 class1 = new Class1();public Form1(){InitializeComponent();}/// <summary>/// 隐藏当前窗体//调用公共类中的方法接收信息/// </summary>private void Form1_Load(object sender, EventArgs e){Hide();class1.StartListener();}}
}

3.客户端

// 客户端端，要增加对公共类的引用
using StartListener;
using System.Diagnostics;
using System;
using System.Windows.Forms;namespace ChatClient
{public partial class Form1 : Form{       Process myProcess;public Form1(){InitializeComponent();}/// <summary>///  开启服务器///  要把服务器端生成的.exe文件复制到客户端当前文件夹下///  并且文件名要修改为实际生成的文件名/// </summary>private void Form1_Load(object sender, EventArgs e){myProcess = Process.Start("ChatServer.exe");   }private void Button1_Click(object sender, EventArgs e){string send = Class1.Send(textBox1.Text, textBox2.Text);MessageBox.Show(send);                      //发送信息//textBox2.Text = string.Empty;textBox2.Focus();}private void TextBox1_KeyPress(object sender, KeyPressEventArgs e){if (e.KeyChar == 13)textBox2.Focus();}private void TextBox2_KeyPress(object sender, KeyPressEventArgs e){if (e.KeyChar == 13)button1.Focus();}private void Form1_FormClosing(object sender, FormClosingEventArgs e){myProcess.Kill();}}
}
