如何能够继续从客户端发送到服务器，而不遵循顺序和冻结

我目前正在做一个服务器与客户端之间聊天的应用程序。它可以工作，但它只能遵循由[客户端发送到服务器]->[服务器再次发送到客户端]开始的顺序。如果服务器没有将其发送回客户端，客户端将保持冻结状态。实际上，我想让我的客户端能够在没有这些序列的情况下继续发送到服务器。有什么建议我可以使用吗?比如后台工作人员之类的?我试过按键，但效果不太好。我会尝试任何建议，谢谢。
第一个代码是我的服务器代码在控制台应用程序和第二个代码是我的客户端代码在windows窗体应用程序。

    {

        TcpClient clientSocket = default(TcpClient);
        serverSocket.Start();
        Console.WriteLine(">> Server started...");
        clientSocket = serverSocket.AcceptTcpClient();
        Console.WriteLine(">> Accepted connection from client...");
        while ((true))
        {               
            NetworkStream networkStream = clientSocket.GetStream();                               
            byte[] bytesFrom = new byte[10025];
            networkStream.Read(bytesFrom, 0, (int)clientSocket.ReceiveBufferSize);
            if (bytesFrom[0].ToString() != "0")                                     //listen from client

                Console.WriteLine("<< Client : " + dataFromClient);
            }
