c# - How to convert PCM data to wav file? -

-

i have data in rawdata1 aray short array. have converted byte aray.then created wav file header , header , byte array data written in file. getting error "windows media player getting problem while playing file".can body me?

        public void save file         {          byte[] byte_array = new byte[rawdata1.length * 2];         (int = 0; < rawdata1.length; ++i)         {             //byte_array[2 * i] = getbyte1(rawdata1[i]);             //byte_array[2 * + 1] = getbyte2(rawdata1[i]);             byte_array[2 * i] = getbyte2(rawdata1[i]);             byte_array[2 * + 1] = getbyte1(rawdata1[i]);         }          uint numsamples = 44100;         ushort numchannels = 2;         ushort samplelength = 1; // in bytes         uint samplerate = 22050;          storagefolder storagefolder = knownfolders.musiclibrary;         storagefile file = await storagefolder.createfileasync("sample.wav",     creationcollisionoption.generateuniquename);          stream stream = await file.openstreamforwriteasync();         binarywriter wr = new binarywriter(stream);          wr.write("riff".tochararray());         wr.write(36 + numsamples * numchannels * samplelength);         wr.write("wavefmt".tochararray());         wr.write(16);         wr.write((ushort)1);         wr.write(numchannels);         wr.write(samplerate);         wr.write(samplerate * samplelength * numchannels);         wr.write(samplelength * numchannels);         wr.write((ushort)(8 * samplelength));         wr.write("data".tochararray());         wr.write(numsamples * samplelength);         wr.write(byte_array);         wr.dispose();         stream.dispose();        }        public static byte getbyte1(short s)        {         return (byte)s;        }         public static byte getbyte2(short s)        {         int temp= s >> 8;         return (byte)temp;        }

can me?
