C# 如何在NAudio MP3流媒体部分使用曲目栏

我正在使用C#中的NAudio库，我需要一个轨迹栏来控制音乐。在NAudio Mp3Stream示例项目中，我们有标准控件，如播放、停止、暂停、音量，但没有轨迹栏

我可以在Mp3Stream中使用轨迹栏吗？因为当我在do命令上设置断点时，readFullyStream变量中的CanSeek属性为false

如何在流媒体中使用曲目栏

using (var responseStream = resp.GetResponseStream())
{
var readFullyStream = new ReadFullyStream(responseStream);
do
{
    if (IsBufferNearlyFull)
    {
        Debug.WriteLine("Buffer getting full, taking a break");
        Thread.Sleep(500);
    }
    else
    {
        Mp3Frame frame;
        try
        {
            frame = Mp3Frame.LoadFromStream(readFullyStream);
        }
        catch (EndOfStreamException)
        {
            fullyDownloaded = true;
            // reached the end of the MP3 file / stream
            break;
        }
        catch (WebException)
        {
            // probably we have aborted download from the GUI thread
            break;
        }
        if (decompressor == null)
        {
            // don't think these details matter too much - just help ACM select the right codec
            // however, the buffered provider doesn't know what sample rate it is working at
            // until we have a frame
            decompressor = CreateFrameDecompressor(frame);
            bufferedWaveProvider = new BufferedWaveProvider(decompressor.OutputFormat);
            bufferedWaveProvider.BufferDuration = TimeSpan.FromSeconds(20); // allow us to get well ahead of ourselves
            //this.bufferedWaveProvider.BufferedDuration = 250;
        }
        int decompressed = decompressor.DecompressFrame(frame, buffer, 0);
        //Debug.WriteLine(String.Format("Decompressed a frame {0}", decompressed));
        bufferedWaveProvider.AddSamples(buffer, 0, decompressed);
    }

} while (playbackState != StreamingPlaybackState.Stopped);
Debug.WriteLine("Exiting");
// was doing this in a finally block, but for some reason
// we are hanging on response stream .Dispose so never get there
decompressor.Dispose();
}

NAudio流媒体演示只需在MP3帧到达时解压缩并播放。没有代码存储以前接收到的音频。因此，如果您想要倒带的能力，您需要实现它

一个选项，您可以考虑使用<代码> MediaFoundationReader <代码>，将流URL作为路径传递。这可以在下载时播放音频，还应该支持重新定位
