嗨，我已经做了一些试验与WAV文件，我需要能够播放WAV文件流。我会做什么是打开一个文件，得到的wav文件的原始数据。我通过使用由NightFox提供的这个类:
http://www.codeproject.com/KB/audio-video/CSharpWAVClassAndMixing.aspx
然后，当我有我的原始数据，提取使用WAVFile是建在函数GetNextSampleAs16Bit（）。
这里是，我的类:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
// I want to be able to input a list of shorts, and it will give me
// a playable stream internal wav file.
namespace Aurasen
{
class InternalWAVFile
{
private MemoryStream mMemoryStream;
private bool mStereo;
private int mSampleRateHz;
private short mBitsPerSample;
private int mDataSizeBytes;
public InternalWAVFile(short[] samples, bool pStereo, int pSampleRateHz, short pBitsPerSample)
{
if (mMemoryStream != null)
{
mMemoryStream.Close();
mMemoryStream.Dispose();
mMemoryStream = null;
}
mMemoryStream = new MemoryStream();
mStereo = pStereo;
mSampleRateHz = pSampleRateHz;
mBitsPerSample = pBitsPerSample;
Create();
foreach (short s in samples)
{
byte[] buffer = BitConverter.GetBytes(s);
if (!BitConverter.IsLittleEndian)
Array.Reverse(buffer);
AddSample_ByteArray(buffer);
}
mMemoryStream.Close();
}
public MemoryStream GetStream()
{
return mMemoryStream;
}
private void AddSample_ByteArray(byte[] pSample)
{
try
{
int numBytes = pSample.GetLength(0);
mMemoryStream.Write(pSample, 0, numBytes);
}
catch

}
// Adds the header to the memory stream so that now I can add the data

if (mWAVHeader == null)
mWAVHeader = new char[4];
"RIFF".CopyTo(0, mWAVHeader, 0, 4);
// File size size (4 bytes) - This will be 0 for now
Array.Clear(buffer, 0, buffer.GetLength(0));

// The rest of the file is the audio data
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
}
private static byte[] StrToByteArray(String pStr)
{
System.Text.ASCIIEncoding encoding = new System.Text.ASCIIEncoding();
return encoding.GetBytes(pStr);
}
}
}
但由于某些原因，当我用这个功能来发挥这样的音频:
它是所有说的头信息被破坏，即使我使用的建设作为类的WAVFile用途的创造者的wav文件内容相同的方法。
没有任何人有任何建议吗？{BR}
