从.net套接字的无限循环中获取变量
本文关键字:获取 变量 无限循环 net 套接字 | 更新日期: 2023-09-27 18:07:24
我正在使用。net同步套接字从客户端向服务器发送数据。
我需要从StartListening()
方法中获取数据,以便在Main()
中使用它变量数据在无限循环( while(true))
内。请帮忙好吗?
这是服务器代码:
using System;
using System.Threading;
using System.Net;
using System.Net.Sockets;
using System.Text;
public class SynchronousSocketListener
{
byte[] bytes = new Byte[1024];
IPHostEntry ipHostInfo;
IPAddress ipAddress ;
IPEndPoint localEndPoint;
Socket listener;
// Incoming data from the client.
public static string data = null;
// Volatile is used as hint to the compiler that this data
// member will be accessed by multiple threads.
private volatile bool _shouldStop;
public void InitializeListening()
{
// Data buffer for incoming data.
// Establish the local endpoint for the socket.
// Dns.GetHostName returns the name of the
// host running the application.
ipHostInfo = Dns.Resolve("localhost");
ipAddress = ipHostInfo.AddressList[0];
localEndPoint = new IPEndPoint(ipAddress, 11007);
// Create a TCP/IP socket.
listener = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
listener.Bind(localEndPoint);
listener.Listen(10);
}
public void StopListening()
{
_shouldStop = true;
byte[] msg = Encoding.ASCII.GetBytes("please stop!");
// Create a TCP/IP socket.
Socket sender = new Socket(AddressFamily.InterNetwork,
SocketType.Stream, ProtocolType.Tcp);
// Connect the socket to the remote endpoint. Catch any errors.
try {
sender.Connect(localEndPoint);
// Send the data through the socket.
int bytesSent = sender.Send(msg);
// Release the socket.
sender.Shutdown(SocketShutdown.Both);
sender.Close();
}
catch (ArgumentNullException ane)
{
Console.WriteLine("ArgumentNullException : {0}", ane.ToString());
}
catch (SocketException se)
{
Console.WriteLine("SocketException : {0}", se.ToString());
}
catch (Exception e)
{
Console.WriteLine("Unexpected exception : {0}", e.ToString());
}
}
public void StartListening()
{
// Bind the socket to the local endpoint and
// listen for incoming connections.
try
{
// Start listening for connections.
while (true)
{
Console.WriteLine("Waiting for a connection...");
// Thread is suspended while waiting for an incoming connection.
Socket handler = listener.Accept();
// An incoming connection needs to be processed.
if (_shouldStop)
{
handler.Shutdown(SocketShutdown.Both);
handler.Close();
break;
}
data = null;
while (true)
{
bytes = new byte[1024];
int bytesRec = handler.Receive(bytes);
data += Encoding.ASCII.GetString(bytes, 0, bytesRec);
if (data.IndexOf("<EOF>") > -1)
{
break;
}
}
// Show the data on the console.
Console.WriteLine("Text received : {0}", data);
// Echo the data back to the client.
//byte[] msg = Encoding.ASCII.GetBytes(data);
byte[] msg = Encoding.ASCII.GetBytes("Salam !");
handler.Send(msg);
handler.Shutdown(SocketShutdown.Both);
handler.Close();
}
}
catch (Exception e)
{
Console.WriteLine(e.ToString());
}
}
public static int Main(String[] args)
{
Console.WriteLine("I am the Synchronous Socket Server'n");
SynchronousSocketListener pServer = new SynchronousSocketListener();
pServer.InitializeListening();
Thread serverkerThread = new Thread(pServer.StartListening);
serverkerThread.Start();
// Loop until server thread activates.
while (!serverkerThread.IsAlive) ;
Console.WriteLine("listening thread sevice started...'n");
Console.WriteLine("'nPress Q when you want to quit...'n");
int car;
do
{
Thread.Sleep(100);
car = Console.Read();
if (car == 81)
{
// Request that the worker thread stop itself:
pServer.StopListening();
// Use the Join method to block the current process
// until the object's thread terminates.
serverkerThread.Join();
break;
}
} while (true);
Console.WriteLine("listening thread sevice stopped and program will be exited...'n");
return 0;
}
}
接收到的数据(给定它是一个以"EOF"结尾的ascii字符串)存储在pServer对象的名为"data"的公共成员中,您可以像这样访问它:
Thread serverkerThread = new Thread(pServer.StartListening);
serverkerThread.Start();
// Loop until server thread activates.
while (!serverkerThread.IsAlive) ;
string receivedString = pServer.data; // <<--- here we get the received string
Console.WriteLine("listening thread sevice started...'n");
