实现效果：
知识运用：
TcpListener TcpClient 和 NetworkStream类 及 Timer组件
1> TcpListener类 //用来从Tcp网络客户端侦听连接
2> TcpClient类 //为Tcp网络服务提供客户端连接
public TcpClient(string hostname,int port) //远程主机的DNS名 端口号
3> NetworkStream类 //提供在阻止模式下通过Stream套接字发送和接受数据的方法
//其Read方法用于从NetworkStream类读取数据
public override int Read(byte[] buffer,int offset,int size)
4> notifyIcon控件的Icon属性
实现代码：
//声明变量
private Thread td;
private string message = "";
private TcpListener tcpListener;
//监听方法
private void startListen()
{
tcpListener = new TcpListener(999);
tcpListener.Start();
while (true)
{
TcpClient client = tcpListener.AcceptTcpClient();
NetworkStream netStream = client.GetStream();
byte[] bt=new byte[1024];
netStream.Read(bt,0,bt.Length);
message = Encoding.Default.GetString(bt);
}
}
//发送消息
private void button1_Click(object sender, EventArgs e)
{
TcpClient client = new TcpClient(textBox1.Text,999);
string msg = "嗨,你好！ 南极鱼";
NetworkStream netStream = client.GetStream();
StreamWriter sw = new StreamWriter(netStream);
sw.WriteLine(msg);
sw.Flush();
sw.Close();
client.Close();
}
//初始化
private void Form1_Load(object sender, EventArgs e)
{
td = new Thread(new ThreadStart(startListen));
td.Start();
timer1.Start();
}
//清理工作
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
if (td.ThreadState == ThreadState.Running)
td.Abort();
if (tcpListener != null)
tcpListener.Stop();
}
//定时检查有无消息
bool flag;
private void timer1_Tick(object sender, EventArgs e)
{
if (message.Length > 0)
{
if(flag)
{ notifyIcon1.Icon = Properties.Resources._1; flag = false; }
else
{ notifyIcon1.Icon = Properties.Resources._2; flag = true; }
}
}
//停止闪烁
private void button2_Click(object sender, EventArgs e)
{
message = "";
notifyIcon1.Icon = Properties.Resources._3;
}
