将字节数组转换为wav文件

I'm trying to play a wav sound that stored in byte array called bytes. I know that I should convert the byte array to wav file and save it in my local drive then called the saved file but I was not able to convert the byte array to wav file.

我想播放一个wav声音，存储在字节数组中。我知道我应该将字节数组转换为wav文件，并将其保存在本地驱动器中，然后调用已保存的文件，但我无法将字节数组转换为wav文件。

please help me to give sample code to convert byte arrary of wav sound to wav file.

请帮助我提供示例代码，将wav声音的字节arrary转换为wav文件。

here is my code:

这是我的代码:

protected void Button1_Click(object sender, EventArgs e)
{
    byte[] bytes = GetbyteArray();

   //missing code to convert the byte array to wav file

    .....................

    System.Media.SoundPlayer myPlayer = new System.Media.SoundPlayer(myfile);
    myPlayer.Stream = new MemoryStream();
    myPlayer.Play();
}

3 个解决方案

#1

Try this:

试试这个:

System.IO.File.WriteAllBytes("yourfilepath.wav", bytes);

#2

You can use something like File.WriteAllBytes(path, data) or...

你可以使用文件之类的东西。WriteAllBytes(路径、数据)或…

...Alternatively if you don't want to write the file you could convert the byte array to a stream and then play that...

…或者，如果您不想编写文件，您可以将字节数组转换为流，然后播放……

var bytes = File.ReadAllBytes(@"C:\WINDOWS\Media\ding.wav"); // as sample

using (Stream s = new MemoryStream(bytes))
{
    // http://msdn.microsoft.com/en-us/library/ms143770%28v=VS.100%29.aspx
    System.Media.SoundPlayer myPlayer = new System.Media.SoundPlayer(s);
    myPlayer.Play();
}

Using NAudio and you can try something like:

使用NAudio，你可以试试:

//var wavReader = new WaveFileReader(yourWavFilePath);
//byte[] buffer = new byte[2 * wav1Reader.WaveFormat.SampleRate * wav1Reader.WaveFormat.Channels];
byte[] buffer = YourWaveSoundByteArray;

using ( WaveFileWriter writer = new WaveFileWriter(YourOutputFilePath, new WaveFormat( AssignWaveFormatYouWant /*wavReader.WaveFormat.SampleRate, 16, 2/*how many channel*/))
    )
{
    //int bytesRead;
    //while ((bytesRead = wavReader.Read(buffer, 0, buffer.Length)) > 0)
    //{
        writer.Write(buffer, 0,  buffer.Length/*bytesRead*/);
    //}
}
