{
  int maxchunk = 1024;
    for(long x = 0; x < totalChunk; x++ )
    {
        long LefttotalLegth = filesize - (x * maxchunk);
        long leghtcopy = Math.Min(maxchunk, LefttotalLegth);
        byte[] chunkbyte = new byte[leghtcopy];        
        sr.Read(chunkbyte, 0, chunkbyte.Length);
       //Do something after read. like write to file
