C# 怎樣通過ip和端口向一台設備發送指令

我有這台設備的維護書，上面有修改設備出廠ip地址的指令，還有回復指令這些，怎麼修改？？求大神！急急急

最佳回答：

直接socket編程呗，知道端口和ip直接發送數據流就行吧

 using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.Net.Sockets;
namespace Client
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                int port = 2000;
                string host = "127.0.0.1";
               ///創建終結點EndPoint
                IPAddress ip = IPAddress.Parse(host);
                //IPAddress ipp = new IPAddress("127.0.0.1");
                IPEndPoint ipe = new IPEndPoint(ip, port);//把ip和端口轉化為IPEndpoint實例

              ///創建socket並連接到服務器
                Socket c = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);//創建Socket
                Console.WriteLine("Conneting…");
                c.Connect(ipe);//連接到服務器

              ///向服務器發送信息
                string sendStr = "hello!This is a socket test";
                byte[] bs = Encoding.ASCII.GetBytes(sendStr);//把字符串編碼為字節
                Console.WriteLine("Send Message");
                c.Send(bs, bs.Length, 0);//發送信息

             ///接受從服務器返回的信息
                string recvStr = "";
                byte[] recvBytes = new byte[1024];
                int bytes;
                bytes = c.Receive(recvBytes, recvBytes.Length, 0);//從服務器端接受返回信息
                recvStr += Encoding.ASCII.GetString(recvBytes, 0, bytes);
                Console.WriteLine("client get message:{0}", recvStr);//顯示服務器返回信息
              ///一定記著用完socket後要關閉
                c.Close();
            }
            catch (ArgumentNullException e)
            {
                Console.WriteLine("argumentNullException: {0}", e);
            }
            catch (SocketException e)
            {
                Console.WriteLine("SocketException:{0}", e);
            }
            Console.WriteLine("Press Enter to Exit");
        }
    }
}
