串联波文件使用CSharp 2005

private void WaveHeaderIN(string spath)
        {
            FileStream fs = new FileStream(spath, FileMode.Open, FileAccess.Read);
            BinaryReader br = new BinaryReader(fs);
            length = (int)fs.Length - 8;
            fs.Position = 22;
            channels = br.ReadInt16();
            fs.Position = 24;
            samplerate = br.ReadInt32();
            fs.Position = 34;
            BitsPerSample = br.ReadInt16();
            DataLength = (int)fs.Length - 44;
            br.Close ();
            fs.Close();
        }

private void WaveHeaderOUT(string sPath)
        {
            FileStream fs = new FileStream(sPath, FileMode.Create, FileAccess.Write );
            BinaryWriter bw = new BinaryWriter(fs);
            bw.Write(new char[4] { 'R', 'I', 'F', 'F' });
            bw.Write(length);
            bw.Write(new char[8] {'W','A','V','E','f','m','t',' '});
            bw.Write((int)16);
            bw.Write((short)1);
            bw.Write(channels);
            bw.Write(samplerate );
            bw.Write((int)(samplerate * ((BitsPerSample * channels) / 8)));
            bw.Write((short )((BitsPerSample * channels) / 8));
            bw.Write(BitsPerSample);  

            bw.Write(new char[4] {'d','a','t','a'});
            bw.Write(DataLength);
            bw.Close();
            fs.Close();
        }
We must be careful when wrriting the header. If there is any small mistake, the merged file doesn't work, so we write "RIFF" as an array of char, not as string and use int type for storing 4 bytes and short type for storing 2 bytes.
我们必须小心写头。如果有任何小小的失误，合并后的文件不工作，所以我们写“釜山国际电影节”作为一个char数组，而不是字符串，用于存储4字节，存放2字节短型int类型。 
Write Data of all Files in the Merged File
写入数据合并的文件中的所有文件 
  public void Merge(string[] files, string outfile)
        {
            WaveIO wa_IN = new WaveIO();
            WaveIO wa_out = new WaveIO();
            wa_out.DataLength = 0;
            wa_out.length = 0;
            //Gather header data
            foreach (string path in files)
            {
                wa_IN.WaveHeaderIN(@path);
                wa_out.DataLength += wa_IN.DataLength;
                wa_out.length += wa_IN.length;
            }
            //Reconstruct new header
            wa_out.BitsPerSample = wa_IN.BitsPerSample;
            wa_out.channels = wa_IN.channels;
            wa_out.samplerate = wa_IN.samplerate;
            wa_out.WaveHeaderOUT(@outfile);
            foreach (string path in files)
            {
                FileStream fs = new FileStream(@path, FileMode.Open, FileAccess.Read);
                byte[] arrfile = new byte[fs.Length - 44];
                fs.Position = 44;
                fs.Read(arrfile, 0, arrfile.Length);
                fs.Close();
                FileStream fo =
                    new FileStream(@outfile, FileMode.Append, FileAccess.Write);
                BinaryWriter bw = new BinaryWriter(fo);
                bw.Write(arrfile);
                bw.Close();
                fo.Close();
            }
          }

First we need to calculate the total length and data length of all files and then specify the channels, SampleRate and BitsPerSample of the output file.The last thing is to start reading data that is stored after byte number 44 and append it to the merged file.
首先，我们需要计算的总长度和数据长度的所有文件，然后指定的渠道，采样频率和输出file.The bitspersample的最后一件事是开始读取存储的字节数后44和追加到文件中的数据合并。 
All we need to do is call the Merge method and specify the input files and output file.
所有我们需要做的就是调用合并方法，并指定输入文件和输出文件。 
string[] files = new string[2] { @"C:\WINDOWS\Media\Windows XP Startup.wav",
                @"C:\WINDOWS\Media\Windows XP Shutdown.wav" };
WaveIO wa = new WaveIO();
wa.Merge(files,@"c:\oou.wav");

Play the Merged File
合并文件播放 
Visual Studio 2005 provides a new class to play sound. Therefore, we don't need an API or anything else.
Visual Studio 2005提供一个新类播放声音。因此，我们并不需要一个API或任何东西。 
FileStream fs = new FileStream(@"c:\oou.wav", FileMode.Open,FileAccess.Read);
System.Media.SoundPlayer sp = new System.Media.SoundPlayer(fs);
sp.Play();
fs.Close();
