System.TypeLoadException: Could not load type 'System.IO.InvalidDataException' from assembly 'NAudio'. How to fix?

Question

C++ / C#

I'm trying to make an object of class AudioClip from MP3 file byte array, follow this guide:
https://gamedev.stackexchange.com/questions/114885...

Here is my code:

public void makeSound(CommandArgs args)
        {
      try
      {
        var bytes_music = File.ReadAllBytes("Unturned_Data/Managed/mods/clip.mp3");
        Reference.Tell(args.sender.networkPlayer, "Working x0");
        AudioClip audioClip = NAudioPlayer.FromMp3Data(bytes_music);
        AudioSource.PlayClipAtPoint(audioClip, args.sender.position, 1.0f);
        Reference.Tell(args.sender.networkPlayer, "Successfully created sound");
      }
      catch(Exception ex)
            {
        Reference.Tell(args.sender.networkPlayer, $"Error: {ex}");
        StreamWriter streamWriter = new StreamWriter("Unturned_Data/Managed/mods/error.txt");
        streamWriter.WriteLine(ex);
        streamWriter.Close();
            }
    }

As shown in the article, I also made 2 classes: WAV and NAudioPlayer.

public static class NAudioPlayer
{
    public static AudioClip FromMp3Data(byte[] data)
    {
        // Load the data into a stream
        MemoryStream mp3stream = new MemoryStream(data);
        // Convert the data in the stream to WAV format
        Mp3FileReader mp3audio = new Mp3FileReader(mp3stream);
        WaveStream waveStream = WaveFormatConversionStream.CreatePcmStream(mp3audio);
        // Convert to WAV data
        WAV wav = new WAV(AudioMemStream(waveStream).ToArray());
        Debug.Log(wav);
        AudioClip audioClip = AudioClip.Create("testSound", wav.SampleCount, 1, wav.Frequency, false, false);
        audioClip.SetData(wav.LeftChannel, 0);
        // Return the clip
        return audioClip;
    }

    private static MemoryStream AudioMemStream(WaveStream waveStream)
    {
        MemoryStream outputStream = new MemoryStream();
        using (WaveFileWriter waveFileWriter = new WaveFileWriter(outputStream, waveStream.WaveFormat))
        {
            byte[] bytes = new byte[waveStream.Length];
            waveStream.Position = 0;
            waveStream.Read(bytes, 0, Convert.ToInt32(waveStream.Length));
            waveFileWriter.Write(bytes, 0, bytes.Length);
            waveFileWriter.Flush();
        }
        return outputStream;
    }
}

WAV:

public class WAV
{

    // convert two bytes to one float in the range -1 to 1
    static float bytesToFloat(byte firstByte, byte secondByte)
    {
        // convert two bytes to one short (little endian)
        short s = (short)((secondByte << 8) | firstByte);
        // convert to range from -1 to (just below) 1
        return s / 32768.0F;
    }

    static int bytesToInt(byte[] bytes, int offset = 0)
    {
        int value = 0;
        for (int i = 0; i < 4; i++)
        {
            value |= ((int)bytes[offset + i]) << (i * 8);
        }
        return value;
    }
    // properties
    public float[] LeftChannel { get; internal set; }
    public float[] RightChannel { get; internal set; }
    public int ChannelCount { get; internal set; }
    public int SampleCount { get; internal set; }
    public int Frequency { get; internal set; }

    public WAV(byte[] wav)
    {

        // Determine if mono or stereo
        ChannelCount = wav[22];     // Forget byte 23 as 99.999% of WAVs are 1 or 2 channels

        // Get the frequency
        Frequency = bytesToInt(wav, 24);

        // Get past all the other sub chunks to get to the data subchunk:
        int pos = 12;   // First Subchunk ID from 12 to 16

        // Keep iterating until we find the data chunk (i.e. 64 61 74 61 ...... (i.e. 100 97 116 97 in decimal))
        while (!(wav[pos] == 100 && wav[pos + 1] == 97 && wav[pos + 2] == 116 && wav[pos + 3] == 97))
        {
            pos += 4;
            int chunkSize = wav[pos] + wav[pos + 1] * 256 + wav[pos + 2] * 65536 + wav[pos + 3] * 16777216;
            pos += 4 + chunkSize;
        }
        pos += 8;

        // Pos is now positioned to start of actual sound data.
        SampleCount = (wav.Length - pos) / 2;     // 2 bytes per sample (16 bit sound mono)
        if (ChannelCount == 2) SampleCount /= 2;        // 4 bytes per sample (16 bit stereo)

        // Allocate memory (right will be null if only mono sound)
        LeftChannel = new float[SampleCount];
        if (ChannelCount == 2) RightChannel = new float[SampleCount];
        else RightChannel = null;

        // Write to double array/s:
        int i = 0;
        while (pos < wav.Length)
        {
            LeftChannel[i] = bytesToFloat(wav[pos], wav[pos + 1]);
            pos += 2;
            if (ChannelCount == 2)
            {
                RightChannel[i] = bytesToFloat(wav[pos], wav[pos + 1]);
                pos += 2;
            }
            i++;
        }
    }

    public override string ToString()
    {
        return string.Format("[WAV: LeftChannel={0}, RightChannel={1}, ChannelCount={2}, SampleCount={3}, Frequency={4}]", LeftChannel, RightChannel, ChannelCount, SampleCount, Frequency);
    }
}

What is the System.TypeLoadException error?

Answer 1

There are not enough others DLLon which it depends NAudio.

Answer 2

Can you post the whole project?
