如何在实体框架 6 中创建字段并从连接表中获取数据

Question

I'm using EF6 Code First to work. First I created 2 class:

public class Course
{
    public int Id { get; set; }
    public string Title { get; set; }
    public ICollection<Tag> Tags { get; set; }
}
public class Tag
{
    public int Id { get; set; }
    public string Name{ get; set; }
    public ICollection<Course> Courses { get; set; }
}

After add-migration and update-database, I have 3 table Courses, Tags and TagCourses. But I dont have TagCourse class in project. How can I add new fields like Details on TagCourses and CRUD this joined table?

This might work for you

public class Course
{
    public int Id { get; set; }
    public string Title { get; set; }
    public ICollection<TagCourse> TagCourses{ get; set; }
}

public class TagCourse
{
   public int CourseId {get;set; }
   public int TagId {get;set; }

   public string Details {get;set; }
}

public class Tag
{
    public int Id { get; set; }
    public string Name{ get; set; }
    public ICollection<TagCourse> TagCourses { get; set; }
}
