Use IList to get the JArray Count and Use Loop to Convert into List         var array   result  items   Value lt JArray gt              IList collection    IList array           var list   new List lt string gt              for  int i   0  i  lt  collection Count  j                                list Add collection i  ToString

I can think of different method to achieve the same   IList lt SelectableEnumItem gt  result  array    or  i had some situation that this one didn t work well   var result    List lt SelectableEnumItem gt   array    or use linq extension  var result   array CastTo lt List lt SelectableEnumItem gt  gt       or   var result  array Select x  gt  x  ToArray lt SelectableEnumItem gt       or more explictly   var result  array Select x  gt  new SelectableEnumItem FirstName  x Name  Selected   bool Parse x selected        please pay attention in above solution I used dynamic Object   I can think of some more solutions that are combinations of above solutions  but I think it covers almost all available methods out there   Myself I use the first one

The example in the question is a simpler case where the property names matched exactly in json and in code  If the property names do not exactly match  e g  property in json is  first name    Mark  and the property in code is FirstName then use the Select method as follows  List lt SelectableEnumItem gt  items     JArray array  Select x   gt  new SelectableEnumItem       FirstName    string x  first name        Selected    bool x  selected      ToList
