Turn labels from a CheckBoxList into strings

I have checkboxlist with some items and their names are the directories so I can save the file. I would like to know how I get the name of each label selected from checkboxlist and turn it into a string . I would like to know a way for it to save multiple files at once, which are the ones in checkboxlist .

private void bt_salvar_Click(object sender, EventArgs e)
{
    clsMCI clsmci = new clsMCI();
    string ArtistaDoAlbum;
    string Artista;
    TagLib.File tagFile = TagLib.File.Create(aqui onde gostaria que o nome da label selecionada estivesse);
    tagFile.Tag.Title = tx_titulo.Text;
    tagFile.Save();
}
