using NAudio.Wave;

namespace VoiceChatDemo

            if (receiveThread == null)

                receiveThread = null;
            }
            if (udpClient != null)
            {

            }

        private void waveIn_DataAvailable(object sender, WaveInEventArgs e)

            buffer = e.Buffer;
        }

        private void SendAudio()
        {
            while (isSending)
            {
                if (buffer != null)
                {
                    udpClient.Send(buffer, buffer.Length, remoteEndPoint);
                    buffer = null;
                }

            }
        }

        private void ReceiveAudio()
        {
            while (isReceiving)
            {
                byte[] data = udpClient.Receive(ref remoteEndPoint);
                if (waveOut != null)
                {
                    waveOut.Init(new RawSourceWaveStream(data, 0, data.Length, waveIn.WaveFormat));
                    waveOut.Play();
                }
            }
        }
    }
}

这个示例程序使用 NAudio 库来进行音频的输入和输出，使用 UDP 协议进行音频的传输。你需要在窗体上添加两个文本框和两个按钮，分别用于输入远程主机的 IP 地址和端口号，以及开始和停止音频传输。

注意：此示例程序只是一个简单的示例，没有进行错误处理和异常处理，请勿直接在生产环境中使用。在实际应用中，你需要考虑使用更加健壮和安全的方案来进行音频传输。
