新手插座相关问题 [英] Newbie Socket Related Question
问题描述
我正在尝试连接到套接字以测试服务是否不再侦听。我不需要检查别人抓住插座。我试图检查 拒绝连接异常 - WSAECONNREFUSED 10061,要是我的比赛,我 想
开始,或NBSP;&重启NBSP;一个特定的服务。这里是我到目前为止(任何指针将不胜因为我觉得我在我的水新手头赞赏):
使用系统;
使用System.Collections.Generic;
使用System.Linq;
使用System.Text;
命名空间ConsoleApplication1
{
课程计划
{
static void Main(string [] args)
{
System.Net.IPAddress ip地址= System.Net.Dns.GetHostEntry(QUOT;本地主机")。AddressList中[0];
            试试
{
System.Net.Sockets.TcpListener的TCPListener =新System.Net.Sockets.TcpListener(ip地址,5060);
         &NBSP ;      tcpListener.Start();
}
catch(System.Net.Sockets.SocketException ex)
{
}
}
}
}
您需要使用  TcpClient的类,以检查是否有任何人正在收听的特定端口。

  {
      static void Main(string [] args)
      {
         试试
          {
              Int32端口= 13000;
              TcpClient client = new TcpClient(" 127.0.0.1",port);
              client.Close();
          }
          catch(ArgumentNullException e)
          {
              Console.WriteLine(" ArgumentNullException:{0}",e);
          }
          catch(SocketException e)
          {
              Console.WriteLine(" SocketException:{0}",e);
          }
          Console.WriteLine(" \ n按Enter键继续......");
          Console.Read();
      }
  }
SocketException.ErrorCode属性将告诉你,如果连接被拒绝。

I am trying to connect to a socket to test if a service is no longer listening. I don't need to check for someone else grabbing the socket. I am trying to check for a connection refused exception - WSAECONNREFUSED 10061. If I get a match, I want to start, or restart a specific service. Here's what I have so far (any pointers would be greatly appreciated as I think I am over my novice head in water):
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
System.Net.IPAddress ipAddress = System.Net.Dns.GetHostEntry("localhost").AddressList[0];
try
{
System.Net.Sockets.TcpListener tcpListener = new System.Net.Sockets.TcpListener(ipAddress, 5060);
tcpListener.Start();
}
catch (System.Net.Sockets.SocketException ex)
{
}
}
}
}
You need to use TcpClient class to check if anybody is listening a particular port.
class Program { static void Main(string[] args) { try { Int32 port = 13000; TcpClient client = new TcpClient("127.0.0.1", port); client.Close(); } catch (ArgumentNullException e) { Console.WriteLine("ArgumentNullException: {0}", e); } catch (SocketException e) { Console.WriteLine("SocketException: {0}", e); } Console.WriteLine("\n Press Enter to continue..."); Console.Read(); } }SocketException.ErrorCode property will tell you if connection is refused.
