我有两个类,Group类与User类具有多对多的关系(表示用户所属的组),然后该组也与用户具有一对多的关系类(代表一个组的所有者)。实体框架代码优先映射
如何映射此?
public class User
{
public int Id { get; set; }
public string Avatar { get; set; }
public string Name { get; set; }
public string Message { get; set; }
public virtual ICollection<Group> OwnedGroups { get; set; }
public virtual ICollection<Group> Groups { get; set; }
}
public class Group
{
public int Id { get; set; }
public DateTime CreateDate { get; set; }
public DateTime ModifyDate { get; set; }
public string Name { get; set; }
public string Description { get; set; }
public bool System { get; set; }
public int ViewPolicy { get; set; }
public int JoinPolicy { get; set; }
public string Avatar { get; set; }
public int Order { get; set; }
public int GroupType { get; set; }
public virtual User Owner { get; set; }
public virtual ICollection<User> Members { get; set; }
}
