Question

我正在使用Code First方法，我设计了以下类。

public interface IItem
 {
        public Guid ItemId { get; set; }

        DateTime? CreateDate { get; set; }

        DateTime? ModifyDate { get; set; }

        User CreatedBy { get; set; }

        User ModifiedBy { get; set; }

    }

    public class User : IItem
    {
        public string Email { get; set; }

        public string FirstName { get; set; }

        public string LastName { get; set; }

        public string Name { get; set; }

        public Guid ItemId { get; set; }

        public DateTime? CreateDate { get; set; }

        public DateTime? ModifyDate { get; set; }

        public User CreatedBy { get; set; }

        public User ModifiedBy { get; set; }
    }

    public class Entity1 : IItem
    {
        public string Entity1Prop1 { get; set; }

        public Guid ItemId { get; set; }

        public DateTime? CreateDate { get; set; }

        public DateTime? ModifyDate { get; set; }

        public User CreatedBy { get; set; }

        public User ModifiedBy { get; set; }
    }

现在我需要使用流畅的API定义实体之间的关系。我有以下要求 1.用户表具有主键ItemId 2.用户表colulmns CreatedBy和ModifiedBy引用相同的用户表ItemId列作为ForeignKey 3. Entity1表具有主键ItemId 4.实体表列CreatedBy和ModifiedBy引用用户表itemId作为外键

如何使用Entity框架fluent api为以下用例
