i have created following entity classess db tables

 public class jewelry     {         #region properties         public jewelry_items jewelryitems { get; set; }         public jewelry_addnl_details jewelryaddnldetails { get; set; }         #endregion     }      public class jewelry_items     {          #region properties         [key]         public int jewelryid { get; set; }         public int generalinfoid { get; set; }         public string style { get; set; }         public string jewelrytype { get; set; }         public string jewelrydesc { get; set; }         public string addnldetails { get; set; }         public string otherdetails { get; set; }         public string ringcut { get; set; }         public string modelnumber { get; set; }         public string createdby { get; set; }         public datetime createddate { get; set; }         public string lastmodifiedby { get; set; }         public datetime lastmodifieddate { get; set; }         #endregion     }      public class jewelry_addnl_details     {         #region properties         [key]         public int id { get; set; }         public int jewelryid { get; set; }         public string iscompleteddesc { get; set; }         public string appraisaldate { get; set; }         public int replacementvalue { get; set; }         public string useonbehalf { get; set; }         public string firstname { get; set; }         public string lastname { get; set; }         public string relationship { get; set; }         #endregion     } 

jewelryid has fk relationship between 2 tables. want delete record 2 tables did following . there better way of doing this?

 using (var db = new context())             {                 var jewelryitem = db.jewelryitemslist.singleordefault(x => x.jewelryid == jewelryid);                 var jewelryaddnldetail = db.jewelryaddnldetailslist.singleordefault (x => x.jewelryid == jewelryid);                 if (jewelryaddnldetail != null)                 {                     db.jewelryaddnldetailslist.remove(jewelryaddnldetail);                 }                  if (jewelryitem != null)                 {                     db.jewelryitemslist.remove(jewelryitem);                 }                  db.savechanges();                 issuccess = true;             }

new code

 public class rli_jewelry_items     {          #region properties         [key]         public int jewelryid { get; set; }          [foreignkey("generalinfoid")]         public virtual rli_insured_generalinfo rli_insured_generalinfo { get; set; }          public int generalinfoid { get; set; }          public string style { get; set; }         public string jewelrytype { get; set; }         public string jewelrydesc { get; set; }         public string addnldetails { get; set; }         public string otherdetails { get; set; }         public string ringcut { get; set; }         public string modelnumber { get; set; }         public string createdby { get; set; }         public datetime createddate { get; set; }         public string lastmodifiedby { get; set; }         public datetime lastmodifieddate { get; set; }         #endregion     }      public class rli_jewelry_addnl_details     {         #region properties         [key]         public int id { get; set; }          [required]         [foreignkey("jewelryid")]         public virtual rli_jewelry_items rli_jewelry_items { get; set; }          [required]         public int jewelryid { get; set; }          public string iscompleteddesc { get; set; }         public string appraisaldate { get; set; }         public int replacementvalue { get; set; }         public string useonbehalf { get; set; }         public string firstname { get; set; }         public string lastname { get; set; }         public string relationship { get; set; }         #endregion     }
