The initialization and reconnection of the communication is described in the chapter before. In order to initialize the communication, the MS toggles the Sync flag between 0 and 1 with cycle duration of 500 ms. Once the SC recognizes the Sync flag, it answers with an ACK frame of the same value as the detected Sync flag. The command STA is set to 2 (STA(02)) by the SC to request continuous status information. Hereupon, the MS sends its state with every answer. A prerequisite to accept commands by the MS is STA(01) (reply code from halm MS) and TOK(01). Direction Command code Reply Code Flag Remark SC → MS STA(02),TRG(01) Trigger a measurement * MS → SC Handshake acknowledge MS → SC STA(01), TRG(01) Trigger accepted SC → MS Handshake acknowledge SC → MS STA(02), TRG(FF) Command completed MS → SC Handshake acknowledge MS → SC TRG(FF), STA(02) TOK(FF) Reply completed, MS busy, cell transport not allowed SC → MS Handshake acknowledge MS → SC STA(02) TOK(01) Cell transport allowed SC → MS Handshake acknowledge MS → SC STA(01) RES(01) Measurement result data available SC → MS Handshake acknowledge SC → MS STA(02), GRS(01) MS → SC Handshake acknowledge MS → SC STA(01), GRS(01) RES(FF) Including result data SC → MS Handshake acknowledge SC → MS STA(02), GRS(FF) Command completed MS → SC Handshake acknowledge MS → SC STA(01), GRS(FF) Reply completed SC → MS Handshake acknowledge * SC sends TWO commands within one frame. In consequence, MS will reply with TWO answers. Same procedure for THREE commands. Please always send STA(02) together with every command. Do not send STA(FF) which will stop MS sending status and results.基于此通信协议,帮我用c#写一份DEMO代码

由于没有具体的通信设备和网络环境,以下代码仅提供参考,需要根据实际情况进行修改和适配。
```csharp
using System;
using System.Net.Sockets;
using System.Text;
namespace CommunicationDemo
{
class Program
{
static void Main(string[] args)
{
string ip = "192.168.0.1"; // 通信设备IP地址
int port = 6000; // 通信设备端口号
byte[] receiveBuffer = new byte[1024]; // 接收数据缓冲区
try
{
// 创建TCP客户端
TcpClient client = new TcpClient(ip, port);
// 发送初始化命令
byte[] initCommand = Encoding.ASCII.GetBytes("STA(02),TRG(01)\r\n");
client.GetStream().Write(initCommand, 0, initCommand.Length);
// 接收初始化命令的响应
int receiveLength = client.GetStream().Read(receiveBuffer, 0, receiveBuffer.Length);
string receiveData = Encoding.ASCII.GetString(receiveBuffer, 0, receiveLength);
Console.WriteLine("Receive: " + receiveData);
// 发送连续查询状态命令
byte[] statusCommand = Encoding.ASCII.GetBytes("STA(02)\r\n");
client.GetStream().Write(statusCommand, 0, statusCommand.Length);
// 不断接收状态信息
while (true)
{
receiveLength = client.GetStream().Read(receiveBuffer, 0, receiveBuffer.Length);
receiveData = Encoding.ASCII.GetString(receiveBuffer, 0, receiveLength);
Console.WriteLine("Receive: " + receiveData);
}
// 关闭TCP客户端
client.Close();
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
}
}
}
```
