关于这段代码如何退出程序
各位达达，下面这个程序是一个非常简单的C#聊天程序，基于UDP协议，我的本意是通过最后输入QUIT退出这个程序，在调试的时候也发现确实退出到了Main的最一个的花括号，但是程序还是感觉就那样死了，再也不动了，以下是源码：要同时在本机上运行两个程序才可以演示这个聊天的效果，请达人出来解答一下如何退出这个程序！using System;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Threading;
namespace ChatApp
{
class Chat
{
private static IPAddress remoteIPAddress;
private static int remotePort;
private static int localPort;
[STAThread]
static void Main(string[] args)
{
try
{
// Get necessary data for connection
Console.WriteLine("Enter Local Port");
localPort = Convert.ToInt16(Console.ReadLine());
Console.WriteLine("Enter Remote Port");
remotePort = Convert.ToInt16(Console.ReadLine());
//Console.WriteLine("Enter Remote IP address");
//remoteIPAddress = IPAddress.Parse(Console.ReadLine());
remoteIPAddress = IPAddress.Parse("127.0.0.1");
// Create thread for listening
Thread tRec = new Thread(new ThreadStart(Receiver));
tRec.Start();
while (true)
{
string strValue = Console.ReadLine();
if (strValue.ToUpper() == "QUIT")
{
if (tRec.ThreadState != ThreadState.Stopped)
tRec.Abort();
break;
}
else
{
Send(strValue);
}
}
}
catch (Exception e)
{
Console.WriteLine(e.ToString());
}
Console.WriteLine("Press any key to return");
Console.Read();
}
private static void Send(string datagram)
{
// Create UdpClient
UdpClient sender = new UdpClient();
// Create IPEndPoint with details of remote host
IPEndPoint endPoint = new IPEndPoint(remoteIPAddress, remotePort);
try
{
// Convert data to byte array
byte[] bytes = Encoding.ASCII.GetBytes(datagram);
// Send data
sender.Send(bytes, bytes.Length, endPoint);
}
catch (Exception e)
{
Console.WriteLine(e.ToString());
}
finally
{
// Close connection
sender.Close();
}
}
public static void Receiver()
{
// Create a UdpClient for reading incoming data,
UdpClient receivingUdpClient = new UdpClient(localPort);
// IPEndPoint with remote host information
IPEndPoint RemoteIpEndPoint = null;
try
{
Console.WriteLine(
"-----------*******Ready for chat!!!*******-----------");
while (true)
{
// Wait for datagram
byte[] receiveBytes = receivingUdpClient.Receive(
ref RemoteIpEndPoint);
// Convert and display data
string returnData = Encoding.ASCII.GetString(receiveBytes);
Console.WriteLine("-" + returnData.ToString());
}
}
catch (Exception e)
{
Console.WriteLine(e.ToString());
}
}
}
}
--------------------编程问答-------------------- up --------------------编程问答-------------------- 等待达达出来解决问题 --------------------编程问答-------------------- 这是客户端的代码：
using System;
using System.Collections.Generic;
using System.Text;
using System.IO;
using System.Net;
using System.Net.Sockets;
namespace client
{
class class1
{
static void Main()
{
try
{
int port = 2000;
string host = "127.0.0.1";
IPAddress ip = IPAddress.Parse(host);
IPEndPoint ipe = new IPEndPoint(ip, port);//把ip和端口转化为IPEndPoint实例
Socket c = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);//创建一个Socket
c.Connect(ipe);//连接到服务器
string sendStr = Console.ReadLine();
byte[] bs = Encoding.ASCII.GetBytes(sendStr);
c.Send(bs, bs.Length, 0);//发送测试信息
string recvStr = "";
byte[] recvBytes = new byte[1024];
int bytes;
bytes = c.Receive(recvBytes, recvBytes.Length, 0);//从服务器端接受返回信息
recvStr += Encoding.ASCII.GetString(recvBytes, 0, bytes);
Console.WriteLine("用户2:\n{0}\n用户1:", recvStr);//显示服务器返回信息
c.Close();
Main();
}
catch (ArgumentNullException e)
{
Console.WriteLine("ArgumentNullException:{0}", e);
}
catch (SocketException e)
{
Console.WriteLine("SocketException:{0}", e);
}
Console.ReadLine();
}
}
}
这是服务器端的代码：
using System;
using System.Text;
using System.IO;
using System.Net;
using System.Net.Sockets;
namespace sever
{
class Class2
{
static void Main()
{
try
{
int port = 2000;
string host = "127.0.0.1";
IPAddress ip = IPAddress.Parse(host);
IPEndPoint ipe = new IPEndPoint(ip, port);
Socket s = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);//创建一个Socket类
s.Bind(ipe);//绑定2000端口
s.Listen(0);//开始监听
Socket temp = s.Accept();//为新建连接创建新的Socket。
string recvStr = "";
byte[] recvBytes = new byte[1024];
int bytes;
bytes = temp.Receive(recvBytes, recvBytes.Length, 0);//从客户端接受信息
recvStr += Encoding.ASCII.GetString(recvBytes, 0, bytes);
Console.WriteLine("用户1:\n{0}\n用户2:", recvStr);//把客户端传来的信息显示出来
string sendStr =Console .ReadLine ();
byte[] bs = Encoding.ASCII.GetBytes(sendStr);
temp.Send(bs, bs.Length, 0);//返回客户端成功信息
temp.Close();
s.Close();
Main();
}
catch (ArgumentNullException e)
{
Console.WriteLine("ArgumentNullException:{0}", e);
}
catch (SocketException e)
{
Console.WriteLine("SocketException:{0}", e);
}
Console.ReadLine();
}
}
}
你既然问的是C#，那你电脑上应该按得有vs2005或者vs2008吧，先让服务器端运行，再让客户端运行，就能实现qq聊天功能。 当其中任一端断开时对方就会有提示：另一方已经断开。 试一下吧！
补充：.NET技术 , C#
