Read Twice

[iaiuiuw]

I am looking for some methods help me to read log files from tail to head.
your project is great!
but int this code https://github.com/blakepell/Argus.IO.ReverseFileReader/blob/master/src/Argus.IO.ReverseFileReader/IO/ReverseFileReader.cs

byte[] buf = new byte[1];
            long position = _stream.Position;

            while (_stream.Position > 0)
            {
                buf.Initialize();

                _stream.Seek(-1, SeekOrigin.Current);

                // Read one char
                _stream.Read(buf, 0, 1);

                // Move it back
                _stream.Seek(-1, SeekOrigin.Current);

                if (buf[0] == 10)
                {
                    // Move it back again.
                    _stream.Seek(-1, SeekOrigin.Current);

                    _stream.Read(buf, 0, 1);

                    if (buf[0] == 13)
                    {
                        break;
                    }
                }
            }

            int count = (int)(position - _stream.Position);
            byte[] line = new byte[count];

            _stream.Read(line, 0, count);
            _stream.Seek(-count, SeekOrigin.Current);

            return this.Encoding.GetString(line).Trim(new[] { '\r', '\n' });

Read same char twice, you can improve it.
By the way, _stream.Read(buf, 0, 1); is slow.
_stream.Read(buf, 0, bufferSize); char ch = buf[wantedPosition - bufferStartPosition]; may be better
