实体框架代码优先 - 将两个字段合并为一个集合

我有这个型号和配置

public class Person
 {
     public int? FatherId { get; set; }
     public virtual Person Father { get; set; }
     public int? MotherId { get; set; }
     public virtual Person Mother { get; set; }
     public virtual List<Person> Childs { get; set; }

 }
 class PersonConfiguration : EntityTypeConfiguration<Person>
 {
     public PersonConfiguration()
     {
         HasOptional(e => e.Father).WithMany(e => e.Childs)
              .HasForeignKey(e => e.FatherId);
         HasOptional(e => e.Mother).WithMany(e => e.Childs)
              .HasForeignKey(e => e.MotherId);
     }
 }

我在类型为初始值的情况下收到此错误。

指定的架构无效。错误：(151,6)：错误 0040：类型 Person_Father 未在命名空间 ExamModel (Alias=Self) 中定义。

有没有办法映射Childs两个属性（motherId 和fatherId）的属性？

不可能将两个导航属性映射到单个集合属性。它看起来很可笑，但你必须有两个集合属性

public class Person
 {
     public int? FatherId { get; set; }
     public virtual Person Father { get; set; }
     public int? MotherId { get; set; }
     public virtual Person Mother { get; set; }
     public virtual List<Person> ChildrenAsFather { get; set; }
     public virtual List<Person> ChildrenAsMother { get; set; }
 }

 class PersonConfiguration : EntityTypeConfiguration<Person>
 {
     public PersonConfiguration()
     {
         HasOptional(e => e.Father).WithMany(e => e.ChildrenAsFather)
              .HasForeignKey(e => e.FatherId);
         HasOptional(e => e.Mother).WithMany(e => e.ChildrenAsMother)
              .HasForeignKey(e => e.MotherId);
     }
 }
