如图所示，我把基本通讯功能已经实现，但是我想实现下图中红色圈中部分的功能，自动发送跟数据格式的功能怎么实现啊，希望发送端跟接收端都可以实现这个数据格式的功能，谢谢
整体代码如下：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Linq;
using System;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
//添加的命名空间引用
using System.Net;
using System.Net.Sockets;
using System.Threading;
namespace UDP_扩展开发
{
public partial class UDPTOOL : Form
{
delegate void AddListBoxItemCallback(string text);
AddListBoxItemCallback listBoxCallback;
//使用的接收端口号
private int port = 8001;
private UdpClient udpClient;
public UDPTOOL()
{
InitializeComponent();
listBoxCallback = new AddListBoxItemCallback(AddListBoxItem);
}
private void AddListBoxItem(string text)
{
//如果listBoxReceive被不同的线程访问则通过委托处理；
if (listBoxReceive.InvokeRequired)
{
this.Invoke(listBoxCallback, text);
}
else
{
listBoxReceive.Items.Add(text);
listBoxReceive.SelectedIndex = listBoxReceive.Items.Count - 1;
}
}
/// <summary>

/// </summary>
private void ReceiveData()
{
//在本机指定的端口接收
udpClient = new UdpClient(port);
IPEndPoint remote = null;
//接收从远程主机发送过来的信息；
while (true)
{
try
{
//关闭udpClient时此句会产生异常
byte[] bytes = udpClient.Receive(ref remote);
string str = Encoding.UTF8.GetString(bytes, 0, bytes.Length);
AddListBoxItem(string.Format("来自{0}：{1}", remote, str));
}
catch
{
//退出循环，结束线程
break;
}
}
}
/// <summary>

private void sendData()
{
UdpClient myUdpClient = new UdpClient();
IPAddress remoteIP;
if (IPAddress.TryParse(textBoxRemoteIP.Text, out remoteIP) == false)
{
MessageBox.Show("远程IP格式不正确");
return;
}
IPEndPoint iep = new IPEndPoint(remoteIP, port);
byte[] bytes = System.Text.Encoding.UTF8.GetBytes(textBoxSend.Text);
try
{
myUdpClient.Send(bytes, bytes.Length, iep);
myUdpClient.Close();
textBoxSend.Focus();
}
catch (Exception err)
{
MessageBox.Show(err.Message, "发送失败");
}
finally
{
myUdpClient.Close();
}
}
private void UDPTOOL_Load(object sender, System.EventArgs e)
{
//设置listBox样式
listBoxReceive.HorizontalScrollbar = true;
listBoxReceive.Dock = DockStyle.Fill;
//获取本机第一个可用IP地址
IPAddress myIP = (IPAddress)Dns.GetHostAddresses(Dns.GetHostName()).GetValue(0);
//为了在同一台机器调试，此IP也作为默认远程IP
textBoxRemoteIP.Text = myIP.ToString();
//创建一个线程接收远程主机发来的信息
Thread myThread = new Thread(new ThreadStart(ReceiveData));
//将线程设为后台运行
myThread.IsBackground = true;
myThread.Start();
textBoxSend.Focus();
}
/// <summary>
/// 单击发送按钮触发的事件
/// </summary>
private void buttonSend_Click(object sender, System.EventArgs e)
{
{
sendData();
}
}
/// <summary>
/// 在textBoxSend中按下并释放Enter键后触发的事件
/// </summary>
private void textBoxData_KeyPress(object sender, KeyPressEventArgs e)
{
if (e.KeyChar == (char)Keys.Enter)
sendData();
}
private void UDPTOOL_FormClosing(object sender, FormClosingEventArgs e)
{

}
}
}
如果有大神愿意帮忙可留下自己的qq，我会及时主动加上的，谢谢！
