我正在启动套接字程序，并且正在设置服务器和两种类型的客户端（请求者和仲裁者）。我正在测试连接，但他们并没有工作。现在，我只需为每个表单提供一个按钮：仲裁器的“接受”按钮和请求者的“请求”。每个按钮都应该在另一个窗体上产生一个弹出窗口，但都不起作用。另外，我注意到当我关闭所有程序时，服务器仍然在我的进程中运行。我究竟做错了什么？套接字 - 不发送/接收数据
下面是服务器代码：
namespace FPPLNotificationServer

{

static void Main(string[] args)
{
Console.WriteLine("Starting server on " + Packet.GetIP4Address());
listenerSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
_clients = new List<ClientData>();
IPEndPoint ip = new IPEndPoint(IPAddress.Parse(Packet.GetIP4Address()), 4242);
listenerSocket.Bind(ip);
Thread listenThread = new Thread(ListenThread);
listenThread.Start();
}
static void ListenThread()
{
for (;;)
{
listenerSocket.Listen(0);
_clients.Add(new ClientData(listenerSocket.Accept()));
}
}
public static void Data_IN(object cSocket)
{

byte[] Buffer;
int readBytes;
for (;;)
{
try
{
Buffer = new byte[clientSocket.SendBufferSize];
readBytes = clientSocket.Receive(Buffer);
if(readBytes > 0)
{
Packet packet = new Packet(Buffer);
DataManager(packet);
}
}catch(SocketException ex)
{
Console.WriteLine("Client Disconnected");
}
}
}
public static void DataManager(Packet p)
{
switch (p.packetType)
{
case Packet.PacketType.Notification:
foreach(ClientData c in _clients)
{
c.clientSocket.Send(p.ToBytes());
}
break;
}
}
}

这是我第一次进入socket编程。
