c# - C＃でカスタムファイル拡張子を持つwaveファイルを圧縮する

Question

基本的に、iamが行おうとしているのは、カスタム拡張子を持ついくつかのtxtデータファイルを含むwaveファイルを圧縮することです。たとえば、compressed.bpc「bpc」はカスタムファイル拡張子であることに注意してください。

これまでのところ、私が持っているのは次のようにwaveファイルをロードすることだけです。

public void pictureBox23_Click(object sender, EventArgs e)
{
    ofd.Filter = "WAV|*.wav";
    this.ofd.Multiselect = true;
    if (ofd.ShowDialog() == DialogResult.OK)
    {
        foreach (string fileName in ofd.FileNames)                
        {
        if (System.IO.Path.GetFileName(fileName) == "01.wav")
        {
            label5.Text = System.IO.Path.GetFileName(fileName) + " Ready!";
            label37.Text = System.IO.Path.GetDirectoryName(fileName) + @"\" + System.IO.Path.GetFileName(fileName);
        }
        if (System.IO.Path.GetFileName(fileName) == "02.wav")
        {
            label23.Text = "Beats Loaded";
            label19.Text = System.IO.Path.GetFileName(fileName) + " Ready!";
            label38.Text = System.IO.Path.GetDirectoryName(fileName) + @"\" + System.IO.Path.GetFileName(fileName);
        }
        if (System.IO.Path.GetFileName(fileName) == "03.wav")
        {
            label23.Text = "Beats Loaded";
            label21.Text = System.IO.Path.GetFileName(fileName) + " Ready!";
            label39.Text = System.IO.Path.GetDirectoryName(fileName) + @"\" + System.IO.Path.GetFileName(fileName);

        {
            label23.Text = "Beats Loaded";
            label26.Text = System.IO.Path.GetFileName(fileName) + " Ready!";

例やコードを参考文献などに残してください。Iamはそれほど経験がないので、特定の例やチュートリアルが必要です。
