通达OA使用C#的Socket编程替代PHP中的Socket操作

using System;using System.Collections.Generic;using System.Net;using System.Net.Sockets;using System.Text;using System.Threading;namespace monitorFlowworkAndSubmit.DAL{    class SendSocket    {        string MYOA_TDIM_ADDR = "127.0.0.1";        int MYOA_TDIM_PORT = xxxx;        public string Send()        {            string rst = "";            //设定服务器IP地址            IPAddress ip = IPAddress.Parse(MYOA_TDIM_ADDR);            Socket clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);            try            {                clientSocket.Connect(new IPEndPoint(ip, MYOA_TDIM_PORT)); //配置服务器IP与端口                Console.WriteLine("连接服务器成功");            }            catch (Exception ex)            {                rst = "连接服务器失败，请按回车键退出！";                return ex.ToString();            }            try            {                 string sendMessage = "x^a^admin";                 clientSocket.Send(Encoding.ASCII.GetBytes(sendMessage));                 Console.WriteLine("向服务器发送消息：{0}" + sendMessage);            }            catch            {                 clientSocket.Shutdown(SocketShutdown.Both);                 clientSocket.Close();                 return "sed err";            }            return "OK";        }    }}
