我要评论窗体（richtextbox右显示聊天）
步骤
点击链接按钮
tcpclient客户端步骤
1创建客户端对象
2连接服务器connect
3创建网络基础流发消息 .write发消息
4 创建网络基础流接消息 .read接消息
5 断开连接close()
窗体代码
namespace _02_心跳机制客户端
{
public partial class form1 : form
{
public form1()
{
initializecomponent();
}
tcpclient client;
private void button1_click(object sender, eventargs e)
{
if (button1.text == "连接")
{
try
{
client = new tcpclient();
client.connect(combobox1.text, int.parse(combobox2.text));
button1.text = "断开";
startread();
heartbeat();
}
catch (exception ex)
{
messagebox.show("连接失败");
}
}
else
{
client.close();
timer.stop();
button1.text = "连接";
}
}
void startread()
{
byte[] bs = new byte[1024];
task.run(() =>
{
try
{
while (true)
{
int count = client.getstream().read(bs,0,bs.length);
string msg = encoding.utf8.getstring(bs, 0, count);
richtextbox1.invoke((action)(() =>
{
richtextbox1.appendtext(msg + "\t\n");
}));
}
}
catch (exception ex)
{
button1.text = "连接";
}
});
}
timer timer;
void heartbeat()
{
timer = new timer();
timer.interval = 10000;
timer.tick += timer_tick;
timer.start();
}
private void timer_tick(object sender, eventargs e)
{
client.getstream().write(new byte[] { 1 }, 0, 1);
}
private void button2_click(object sender, eventargs e)
{
byte[] bs = encoding.utf8.getbytes(textbox1.text);
byte[] bs1 = new byte[bs.length + 1];
bs1[0] = 0;
bs.copyto(bs1,1);
client.getstream().write(bs1, 0, bs1.length) ;
}
}
