我有这种情况:

public class Member
{
    public int MemberID { get; set; }

    public string FirstName { get; set; }
    public string LastName { get; set; }

    public virtual ICollection<Comment> Comments { get; set; }
}

public class Comment
{
    public int CommentID { get; set; }
    public string Message { get; set; }

    public virtual ICollection<Member> Members { get; set; }
}

public class MemberComment
{
    public int MemberID { get; set; }
    public int CommentID { get; set; } …

您好,我尝试与EF Fluent API使用多对多关系.我有2个POCO课程.

public class Project
{
    public int ProjectId { get; set; }

    public virtual ICollection<Author> Authors { get; set; }

    public Project()
    {
        Authors = new List<Author>();
    }
}

public class Author
{
    public int AuthorId { get; set; }

    public virtual ICollection<Project> Projects { get; set; }

    public Author()
    {
        Projects = new List<Project>();
    }
}

我用这部分代码映射了很多很多关系:

        ////MANY TO MANY 
        modelBuilder.Entity<Project>()
            .HasMany<Author>(a => a.Authors)
            .WithMany(p => p.Projects)
            .Map(m =>
                     {
                         m.ToTable("ProjectAuthors");
                         m.MapLeftKey("ProjectId");
                         m.MapRightKey("AuthorId");
                     });

这在DB中创建了ProjectsAuthors表.这是我对这种关系映射案例的第一次尝试.

如果我省略了这个映射,它创建了具有类似模式的表AuthorProject.这是正确的bevahior？
