c# - Entity Framework - group multiple foreign keys into a single column -

new ef here , having difficulty.

i have 24 tables need create code-first. each 1 of these tables has around 2 - 10 many-to-one relationships simple , can represented 1 table. here few of classes illustrate structure...

namespace emrs {     public class erecord     {         [key]         public int pcrid { get; set; }         public virtual list<efirstclass> efirstclass {get; set;}         public virtual list<esecondclass> esecondclass { get; set; }     }      public class efirstelement     {         [key]         public int elementid { get; set; }          public elementcode stuff1 { get; set; } //eairway.06         public string stuff2 { get; set; }           public int pcrid { get; set; }         public virtual erecord ereportid { get; set; }          public virtual list<subelement> stuff4list { get; set; }          public virtual list<subelement> stuff5list { get; set; }          public virtual list<subelement> stuff6list { get; set; }          public virtual list<subelement> stuff7list { get; set; }  }      public class esecondelement     {         [key]         public int elementid { get; set; }          public elementcode stuff9 { get; set; }            public elementcode stuff10 { get; set; }          public int pcrid { get; set; }         public virtual erecord ereportid { get; set; }          public virtual list<subelement> stufflist11 { get; set; }           public virtual list<subelement> stufflist12 { get; set; }          public virtual list<subelement> stufflist13 { get; set; }         public virtual list<subelement> stufflist14 { get; set; }           public virtual list<subelement> stufflist15 { get; set; }            public virtual list<subelement> stufflist16 { get; set; }          public virtual list<subelement> stufflist17 { get; set; }  }      public class subelement     {         public int subelementid { get; set; }         public string value { get; set; }         public dynamic type { get; set; }         public int elementid { get; set; }     } } 

if create class/table each individual 1 many relationship in element classes, end many tables same structure. have foreign key in subelement class references more 1 class.

i tried having parentelement abstract class , inheriting in of element classes ef created table class(parentelement) , placed columns in element classes within table.

is there way ef code first?
