通达OA中采用了PHP的语言来进行编程，同样对于IM的有些操作则采用了Socket的方式进行通讯。最近做的一个程序需要采用C#来做，里面涉及到这块，采用C#进行了重写，具体还需要进一步进行测试效果。

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 = "";
            
            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)); 
                Console.WriteLine("conn OK");
            }
            catch (Exception ex)
            {
                rst = "conn err！";
                return ex.ToString();
            }
            try
            {
                 string sendMessage = "x^a^admin";
                 clientSocket.Send(Encoding.ASCII.GetBytes(sendMessage));                
            }
            catch
            {
                 clientSocket.Shutdown(SocketShutdown.Both);
                 clientSocket.Close();
                 return "send error";
            }
            return "OK";
        }
    }
}

通达OA 使用C#的Socket编程来其替代原有操作
