如何正确关闭或处置TCP客户端？

Question

当客户端断开连接时，我在服务器上有以下代码：

更新内部，每帧运行：

foreach (ClientEntity client in connectedClients) {

        if (!isClientStillConnected(client.tcpClient)) {

            disconnectedClients.Add(client);
            client.tcpClient.Close();
            Debug.Log (" :: Client " + client.tcpClientName + " has disconnected! ::");
            continue;

        } else {

            Do_The_Stuff_And_Things();

            }

        }

    }

现在，当我在此之后尝试调试时，仍然在Update（）内部：

for (int i = 0; i < disconnectedClients.Count; i++) {

        Debug.Log(":: Disconnected clients count: " + disconnectedClients.Count.ToString());
        Debug.Log(":: Disconnected client at index " + i + ": " + disconnectedClients[i]);

    }

这部分是从disconnectedClients列表中删除断开连接的客户端，但当我运行它并退出客户端时，这是Unity在控制台中抛出的内容，只是一个片段：

它继续。所以一个 - for loop 不会停止，这意味着客户端不断被添加到列表中，对吧？现在出了什么问题，如何正确删除（关闭）客户端？

在客户端我运行：

        nwReader.Close ();
        nwWriter.Close ();
        tcpClient.Close ();
        socketReady = false;

仅供参考，班级 ClientEntity ：

public class ClientEntity {

  public TcpClient tcpClient;
  public string tcpClientName;

  public ClientEntity(TcpClient tcpClientSocket){

      tcpClientName = "Guest";
      tcpClient = tcpClientSocket;

  }
}

connectedClients方法在您的情况下正常运行。但是，在断开连接后，您不会从if !isClientStillConnected(client.tcpClient)) List / Array中删除客户端，这会导致//This loop is unchanged foreach (ClientEntity client in connectedClients) { if (!isClientStillConnected(client.tcpClient)) { disconnectedClients.Add(client); client.tcpClient.Close(); Debug.Log (" :: Client " + client.tcpClientName + " has disconnected! ::"); continue; } else { Do_The_Stuff_And_Things(); } } } //Remove all disconnected clients from the list of connected clients foreach (var disconnectedClient in disconnectedClients) { connectedClients.Remove(disconnectedClient); } 语句再次评估为true。像这样更改你的代码：
