This is an fraction of the binary writer I'm writing, and I'm trying find some way to improve it, in any possible way.

using System;
using System.Collections.Generic;

public class ByteBuffer
{
    // List used to hold all bytes that will be read
    private List<byte> buffer = new List<byte>(32);

    private int bitIndex = 0;

    /// <summary>
    /// Writes an n bits byte onto the buffer.
    /// </summary>
    public void Write(byte source, int n)
    {
        if ((n + bitIndex) / 8 > buffer.Count)
        {
            buffer.AddRange(new byte[(n + bitIndex) / 8 - buffer.Count]);
        }

        for (int i = 0; i < n; i++)
        {
            buffer[(bitIndex + i) / 8] |= (byte)(((source >> (n - 1 - i)) & 1) << (int)(7 - (bitIndex + i) % 8));
        }

        bitIndex += n;
    }
}

Thanks.
