NHibernate 基於 ClassMapping 的 ManyToMany（多對多配置）實體類

public class Library{    public virtual int Id { get; set; }    public virtual string Name { get; set; }    public virtual IList<Book> Books { get; set; }    public Library()    {        Books = new List<Book>();    }}public class Book{    public virtual int Id { get; set; }    public virtual string Name { get; set; }    public virtual IList<Library> Libraries { get; set; }    public virtual IList<BookLevel> BookLevel { get; set; }    public Book()    {        Libraries = new List<Library>();        BookLevel = new List<BookLevel>();    }}public class BookLevel{    public virtual int Id { get; set; }    public virtual string Name { get; set; }    public virtual IList<Book> Book { get; set; }    public BookLevel()    {        Book = new List<Book>();    }}

ClassMapping 映射類
