TCP監聽器停止監聽

Question

我們目前在Windows服務中託管了一個TCP監聽器。它似乎停止以某個隨機間隔收聽，顯然，當客戶隨後提出請求時，它會被拒絕。我試圖把所有的任務都拿出來，問題仍然存在。不會引發異常，因此沒有任何內容寫入事件日誌。

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(); 
     } 
    } 
}

事實證明，此行爲是由於服務正在重新啓動並且我正在停止收聽。在OnStop函數中調用停止偵聽器來解決問題。
