下面是我的 Chilkat Sockets Server 和客户端代码,运行时出现以下奇怪错误,请帮助我解决它,客户端和服务器都在同一台机器上运行。
服务器代码:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using Chilkat;
using NLog;
namespace SocketsListener
{
public partial class Form2 : Form
{
private Chilkat.Socket _socket;
private readonly Logger _logger = LogManager.GetCurrentClassLogger();
public Form2()
{
InitializeComponent();
Init();
}
private void Init()
{
_socket = new Chilkat.Socket();
var success = _socket.UnlockComponent("registered customer");
if (success != true)
{
return;
}
success = _socket.BindAndListen(5555, 25);
if (success != true)
{
_logger.Error(String.Format("Error: {0}", _socket.LastErrorText));
return;
}
_logger.Info("Service starting...");
var socket = new Chilkat.Socket();
success = _socket.AsyncAcceptStart(0);
while (_socket.AsyncAcceptFinished != true)
{
socket.SleepMs(1);
}
if (!_socket.AsyncAcceptFinished)
{
MessageBox.Show(_socket.LastErrorText);
return;
}
if (!_socket.AsyncAcceptSuccess)
{
MessageBox.Show(_socket.LastErrorText);
return;
}
var connectedSocket = new Socket();
connectedSocket = _socket.AsyncAcceptSocket();
_logger.Info("Data read from Socket at " + connectedSocket.AsyncReceiveUntilMatch("-EOM-"));
//backgroundWorker1.RunWorkerAsync();
}
}
}
客户代码:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using NLog;
using Chilkat;
namespace SocketClient
{
public partial class Form1 : Form
{
private readonly Logger _logger = LogManager.GetCurrentClassLogger();
public Form1()
{
InitializeComponent();
SendMessage();
}
private void SendMessage()
{
var id = Guid.NewGuid();
var socket = new Socket();
var success = socket.UnlockComponent("registered customer");
try
{
if (success != true)
{
return;
}
//success = socket.Connect("192.168.113.39", 5555, false, 0);
success = socket.Connect("localhost", 5555, false, 0);
if (!success)
{
_logger.Info((String.Format("Error: \nunable to connect to host: {0}", socket.LastErrorText)));
}
var message = string.Format("message id {0}\t This is client message -EOM-", id);
socket.MaxSendIdleMs = 10000;
success = socket.SendString(message);
if (!success)
{
_logger.Info((String.Format("Error: \nunable to send message\t MessageId: {0}\nMessage Error {1}",id, socket.LastErrorText)));
}
socket.Close(10000);
}
catch (Exception)
{
throw;
}
}
}
}
