使用naudio播放.wav文件，播放在1秒后停止

我在C＃中使用naudio lib并想播放一个简单的文件。 问题是，播放在1秒后停止。 我无法弄清楚它为什么这样做。

using System; using System.Collections.Generic; using System.Linq; using System.Text; using NAudio.Wave; namespace NAudioTest { class Program { static IWavePlayer waveout; static WaveStream outputStream; static string filename = null; static void Main(string[] args) { waveout = new WaveOut(); filename = "C:\\1.wav"; outputStream = CreateInputStream(filename); try { waveout.Init(outputStream); } catch (Exception ex) { Console.WriteLine("Error while loading output"); Console.WriteLine("Details: " + ex.Message); Console.ReadLine(); return; } Console.WriteLine("Press [Enter] to start playback"); Console.ReadLine(); waveout.Play(); //this stops after 1 sec. should it play until i hit enter cause of the next line? Console.WriteLine("Press [Enter] to abort"); Console.ReadLine(); waveout.Dispose(); Console.ReadLine(); } static WaveStream CreateInputStream(string name) { WaveChannel32 inputStream; if (name.EndsWith(".wav")) { WaveStream readerStream = new WaveFileReader(name); if (readerStream.WaveFormat.Encoding != WaveFormatEncoding.Pcm) { readerStream = WaveFormatConversionStream.CreatePcmStream(readerStream); readerStream = new BlockAlignReductionStream(readerStream); } if (readerStream.WaveFormat.BitsPerSample != 16) { var format = new WaveFormat(readerStream.WaveFormat.SampleRate, 16, readerStream.WaveFormat.Channels); readerStream = new WaveFormatConversionStream(format, readerStream); } inputStream = new WaveChannel32(readerStream); } else { throw new InvalidOperationException("Invalid extension"); } return inputStream; } } }

如果您尝试从控制台应用程序播放音频，则需要确保使用函数回调，因为WaveOut的默认设置是使用窗口回调。

 new WaveOut(WaveCallbackInfo.FunctionCallback()) 

更新：对于较新版本的NAudio，我现在建议您避免使用函数回调，因为它们可能会导致某些驱动程序出现死锁。 相反，使用事件回调和后台线程的WaveOutEvent是首选机制：

 new WaveOutEvent()
