我不明白在C#中使用“while(true)”和“for(;;)”循环！

public void HandleConnection()
    {
        TcpClient tcpClient = tcpListener.AcceptTcpClient();
        NetworkStream networkStream = tcpClient.GetStream();
        while (true)   /**Don't understand this while(true) loop**/
        {
            buffer = new byte[1024];
            n = networkStream.Read(buffer,buffer.Length);
            if (n == 0)
            {
                break;
            }

        }
    }

for(;;)循环的示例代码：

public void readLine(NetworkStream inputStream)
     {
        using (StreamReader reader = new StreamReader(inputStream))
        {

            char[] buffer = new char[128];
            int n;

            for (; ; ) /**Don't understand this for(; ;) loop**/
            {
                n = reader.Read();
                if (n == -1 || n == 'n')
                {
                    break;
                }
        }
      }

任何人都可以通过提供示例代码来清楚地理解上述循环语句吗？谢谢您的帮助！
