TCP监听器停止监听

Question

我们目前在Windows服务中托管了一个TCP监听器。它似乎停止以某个随机间隔收听，显然，当客户随后提出请求时，它会被拒绝。我试图把所有的任务都拿出来，问题仍然存在。不会引发异常，因此没有任何内容写入事件日志。

public void Run() 
{ 
    var tcpDetail = Task.Run(() => _settingsHelper.GetTcpDetail()); 

    if (tcpDetail != null) 
    { 
     var listener = new TcpListener(tcpDetail.Result.ListeningAddress, tcpDetail.Result.ListeningPort); 

     listener.Start(); 

     while (true) 
     { 
      var tcpClient = listener.AcceptTcpClient(); 

      try 
      { 
       Task.Run(() => ProcessClient(tcpClient)); 

      } 
      catch (Exception ex) 
      { 
       EventLog.WriteEntry(AppDomain.CurrentDomain.FriendlyName, ex.Message); 
       if (tcpClient.Client != null && tcpClient.Connected) 
       { 
        tcpClient.Close(); 
       }       
      } 
     } 
    } 
} 


private void ProcessClient(TcpClient client) 
{ 
    try 
    { 
     var networkStream = client.GetStream(); 
     var reader = new StreamReader(networkStream); 


     var networkStream = client.GetStream(); 
     var reader = new StreamReader(networkStream); 

     var request = reader.ReadToEnd(); 

     if (!string.IsNullOrEmpty(request)) 
     { 
      var xmlDocument = new XmlDocument(); 
      xmlDocument.LoadXml(request); 
      _someService.Execute(xmlDocument); 
     } 

    } 
    catch (Exception ex) 
    { 
     EventLog.WriteEntry(AppDomain.CurrentDomain.FriendlyName, ex.Message); 
     if (client.Client != null && client.Connected) 
     { 
      client.Close(); 
     } 
    } 
    finally 
    { 
     if (client.Client != null && client.Connected) 
     { 
      client.Close(); 
     } 
    } 
}

事实证明，此行为是由于服务正在重新启动并且我正在停止收听。在OnStop函数中调用停止侦听器来解决问题。
