二话不说,大家先看一下我服务端添加的引用

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.IO;
using System.Linq;
using System.Net;
using System.Net.Sockets;
using System.Runtime.Serialization.Formatters.Binary;
using System.Text;
using System.Threading;
using System.Windows.Forms;
using commands;


注意一下,这里的最后一个引用commands,与客户端的commands必须是同一个dll,同样的代码编译出来的文件都不行。这是为什么

捏。试想一下,你用一个规则去序列化一个对象,然后用另一个规则进行反序列化,得到的对象不会是原来的对象了吧。


好,下一步。这里是服务器端,每一个客户端连到服务器,都对应一个类的对象,然后把它们搞到一个列表里面。这样就方便进行操作了。在这个基础上,给客户端

发信息,或者转发一个客户端的信息给另一个或多个客户端,都是小case了。

下面就是客户端对应的类了。

public class InConnectUser
{
public TcpClient client { get; set; }
public BinaryReader br { get; set; }
public BinaryWriter bw { get; set; }

public Guid InUseID { get; set; }
public bool IfUserLogin=false;

public Entity.FeeRules obj_enFeeRules = new Entity.FeeRules();
public Entity.InUse obj_enInUse = new Entity.InUse();
public Entity.Computer obj_enComputer = new Entity.Computer();
public Entity.User obj_enUser = new Entity.User();

public InConnectUser(TcpClient client)
{
this.client = client;
NetworkStream networkstream
= client.GetStream();
br
= new BinaryReader(networkstream);
bw
= new BinaryWriter(networkstream);
}
public void Close()
{
br.Close();
bw.Close();
client.Close();
}
}



我这里是和网吧管理相关的,所以加了很多逻辑方面的东西在里面就不贴出来占篇幅了。大家如果把代码copy过去发现出错,就注释掉吧。

话不多,看到关键的地方都写在下面的注释里面。



//在线用户列表
private List<TcpHelper.InConnectUser> onlineUserList = new List<TcpHelper.InConnectUser>();
IPAddress localAddress;
private const int port = 51888;
private TcpListener myListener;

//开启服务器的按钮
private void button_StartServer_Click(object sender, EventArgs e)
{
myListener
= new TcpListener(localAddress, port);
myListener.Start();
label_status.Text
= "开启";

Thread myThread
= new Thread(ListenClientConnect);
myThread.Start();
//timer1.Enabled = true;
button_StartServer.Visible = false;
button_StopServer.Visible
= true;
}
//关闭服务器的按钮
private void button_StopServer_Click(object sender, EventArgs e)
{
label_status.Text
= "关闭";
//关闭服务器,移除list的用户。
//for (int i = onlineUserList.Count - 1; i >= 0; i--)
//{
// RemoveOnlineUser(onlineUserList[i]);
//}
myListener.Stop();
button_StartServer.Visible
= true;
button_StopServer.Visible
= false;
}

/// <summary>
/// 监听连接
/// </summary>
private void ListenClientConnect()
{
TcpClient newClient
= null;
while (true)
{
try
{
//停在此处监听连接,如果有新客户端连接就运行下去
newClient = myListener.AcceptTcpClient();
}
catch (Exception)
{

break;
}
InConnectUser user
= new InConnectUser(newClient);
Thread threadReceive
= new Thread(ReceiveData);
threadReceive.Start(user);
onlineUserList.Add(user);

}

}



/// <summary>

/// <param name="UserState"></param>
private void ReceiveData(object UserState)
{
InConnectUser user
= (InConnectUser)UserState;
TcpClient client
= user.client;
MessageInfo receiveObject;

while (true)
{
try
{
byte[] bytes = new byte[999];
//停在此处,networkstream流中有新数据则读出
int i = user.br.Read(bytes, 0, 999);
MemoryStream memory
= new MemoryStream(bytes);
BinaryFormatter format
= new BinaryFormatter();
receiveObject
= (MessageInfo)format.Deserialize(memory);
}
catch (Exception)
{
return;
}
switch (receiveObject.CommandsTypes)
{
case CommandsTypes.RequestHowLong:
//这里是我处理各种命令的方法,和这个博客的主题无关,就不贴出来了。
//处理好之后,就在这个方法里面发送回应给对应的客户端,所以一定要有参数user
// ManagerHowLong(user);
break;
case CommandsTypes.RequestUserLogin:
// ManagerUserLogin(user, receiveObject);
break;
case CommandsTypes.RequestUserlogout:
// ManagerUserLogout(user);
break;
case CommandsTypes.RequestLogout:
//注意这里是return,本意是如果客户端的连接要关闭, 就用跳出循环
//但是我的是网吧管理,不考虑这种情况,所以就未做处理
return;
case CommandsTypes.RequestModPWD:
// ManagerModPWD(user, receiveObject);
break;
case CommandsTypes.RequestMachineLogin:
// ManagerMachineLogin(user, receiveObject);
break;

case CommandsTypes.RequestTalk:
// ManagerTalk(receiveObject);
break;

default:
break;
}

}

}

/// <summary>
/// 发消息
/// </summary>
/// <param name="user">发给谁</param>
/// <param name="userSend">发送内容</param>
private void SendToClient(TcpHelper.InConnectUser user, MessageInfo userSend)
{
try
{
MemoryStream memory
= new MemoryStream();
BinaryFormatter format
= new BinaryFormatter();
format.Serialize(memory, userSend);
byte[] bytes = memory.ToArray();

user.bw.Write(bytes);
user.bw.Flush();

}
catch (Exception)
{
//发送失败
}
}

代码不多,但是也要花点小时间去看看条理才会清晰。
