首先非常抱歉第三次和第四次作业我没交上来，不想找借口强调原因，但是这两次作业我一定会补上，到时候会@助教。谢谢
回到这次作业！
这次作业邹老师没说博客的格式，所以在这里就没有什么回答问题的东西了。这次由于是*组队我觉得猪脚应该没有我们的名单，所以在这里附上，如下

这次作业主要是做一个服务器与客户端的连接，其中黄金点的算法思想应该是在下一周里面提交，所以在这里面就不说算法了，既然只是简单的建立一个小协议和简单的服务器客户端程序，就没必要大费周章，我是用c#的socket类来简单写的通信，而处理也比较简单。
客户端代码如下：
class client
{
public static string ToBeginGame = "Start";
private static byte[] result = new byte[];
public string sname { get; set; }
public string scode { get; set; } IPAddress ip = IPAddress.Parse("192.168.137.1");
Socket clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); public void Sign_Receive()
{
Thread Client_thread = new Thread(new ThreadStart(ReceiveSMessage));
Client_thread.Start();
} public void ReceiveSMessage()
{ //通过clientSocket接收数据
while (true)
{ int receiveLength = clientSocket.Receive(result); string ss = Encoding.ASCII.GetString(result, , receiveLength); if (ss == ToBeginGame)
{
SendNum();
}
} } public void connnectserver()
{
try
{
clientSocket.Connect(new IPEndPoint(ip, )); //配置服务器IP与端口
Console.WriteLine("连接服务器成功");
}
catch
{
Console.WriteLine("连接服务器失败，请按回车键退出！");
return;
}
} public void Regester()
{
SendClientMessage("Regester"+"+"+sname + "+" + scode);
} public void SignIn()
{
SendClientMessage(sname + "" + scode);
} public void SendNum()
{
Random _random = new Random(); Random r = new Random(); byte[] buffer = Guid.NewGuid().ToByteArray();
int iSeed = BitConverter.ToInt32(buffer, );
r = new Random(iSeed);
int x;
x = r.Next(); SendClientMessage(sname+"+"+x.ToString());
} public void SendClientMessage(string smessage)
{
try
{
clientSocket.Send(Encoding.ASCII.GetBytes(smessage));
}
catch
{
clientSocket.Shutdown(SocketShutdown.Both);
clientSocket.Close();
}
} }
主函数如下：
public static void Main()
{ client[] a = new client[];
for (int i = ; i < ; i++)
{
a[i] = new client { sname = "c-" + i.ToString(), scode = "" };
a[i].connnectserver();
a[i].Sign_Receive();
a[i].Regester();
} Console.ReadLine();
}
服务器代码如下：
class ClientData
{
public string Mname { get; set; }
public string Mcode { get; set; }
public double Mnum { get; set; }
public bool IsSendNum { get; set; }
public Socket client { get; set; }
} class NumSeryer
{ public static DateTime StartTime = new DateTime();
public static DateTime EndTime = new DateTime(); public static List<ClientData> ClientList = new List<ClientData>(); public static int Nround = ; private static byte[] result = new byte[];
private static int myProt = ; //端口
static Socket serverSocket;
public static int nsum;
static void Main(string[] args)
{
//服务器IP地址
IPAddress ip = IPAddress.Parse("127.0.0.1");
serverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
serverSocket.Bind(new IPEndPoint(ip, myProt)); //绑定IP地址：端口
serverSocket.Listen();
Console.WriteLine("启动监听{0}成功", serverSocket.LocalEndPoint.ToString());
//通过Clientsoket发送数据 Thread myThread = new Thread(ListenClientConnect);
myThread.Start();
Console.ReadLine();
} /// 监听客户端连接 /// public static void sendstart()
{ for (int i = ; i < Nround; i++)
{
sendmessage();
Thread.Sleep(); double sum = , ave, jiange = ;
int n = , pos = ; foreach (ClientData xx in ClientList)
{
if (xx.IsSendNum)
{
sum += xx.Mnum;
n++;
}
} ave = sum / n * 0.618; for (int j = ; j < ClientList.Count; j++)
{
ClientData xx = ClientList[j];
if (xx.IsSendNum && jiange > Math.Abs(xx.Mnum - ave))
{
jiange = Math.Abs(xx.Mnum - ave); pos = j;
}
} Console.WriteLine("第{0}轮结果", i);
Console.WriteLine("参与客户端数：{0}，G-number：{1}", n, ave);
Console.WriteLine("获胜客户端名字:{0},数值：{1}", ClientList[pos].Mname, ClientList[pos].Mnum);
Console.WriteLine();
}
} public static void sendmessage()
{
foreach (ClientData xx in ClientList)
xx.client.Send(Encoding.ASCII.GetBytes("Start"));
} private static void ListenClientConnect()
{
while (true)
{
nsum++; StartTime = DateTime.Now; Socket clientSocket = serverSocket.Accept(); ClientData _client = new ClientData { client = clientSocket }; ClientList.Add(_client); Thread receiveThread = new Thread(ReceiveMessage);
receiveThread.Start(clientSocket); if (nsum >= )
{
sendstart();
// return;
} }
} /// <summary>
/// 接收消息
/// </summary>
/// <param name="clientSocket"></param>
/// private static void ReceiveMessage(object clientSocket)
{
Socket myClientSocket = (Socket)clientSocket; while (true)
{
try
{
//通过clientSocket接收数据
int receiveNumber = myClientSocket.Receive(result); string ss = Encoding.ASCII.GetString(result, , receiveNumber); string[] s = ss.Trim().Split('+'); double tnum = ; if (s[] == "Regester")
{
string[] stemp = s[].Trim().Split('-');
int index = int.Parse(stemp[]);
ClientList[index].Mname = s[];
ClientList[index].Mcode = s[];
continue;
} string tname = s[];
tnum = int.Parse(s[]);
int n = ClientList.FindIndex(x => x.Mname == s[]); ClientList[n].Mnum = tnum;
ClientList[n].IsSendNum = true;
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
myClientSocket.Shutdown(SocketShutdown.Both);
myClientSocket.Close();
break;
}
}
}
}
程序的大体框架就是首先服务器通过ListenClientConnect函数来一直监听客户端传来的消息，通过serverSocket.Accept得到socket类，服务器创建了一个客户端list来储存收到的注册的客户端，而没接受一个客户端泽新建一个线程来执行ReceiveMessage函数，ReceiveMessage负责接受注册的信息包括客户端的账号和密码，这里我们吧所有的信息（包括注册的信息和发送的有理数）都一起发送过来，只不过注册的信息开头会有一个Regester来区分，服务器统计我收的客户端数量囚达到20个就开始发送开始游戏命令到每个注册用户中，这时候另一台机（客户端）会建立20个线程（注册用户）来等待开始游戏命令，一旦接受送回一个随机数，每一轮锦标赛服务器都会统计一下在规定的1.2秒内(从发送开始游戏命令开始算起)的参与客户端数量，并算出优胜者，输出当前锦标赛轮数，参与的用户数量，黄金点的值和优胜用户的名字和对应的值；
进行规定论述的锦标赛，输出最佳的人；
