try this one, user json to serialize and deserialize:

 using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Text;
    using System.Threading.Tasks;
    using System.Web.Script.Serialization;

    namespace ConsoleApplication1
    {
       public class Program
       {
          static void Main(string[] args)
          {
              object newobj = new object();

              for (int i = 0; i < 10; i++)
              {
                List temp = new List();

                temp.Add(i);
                temp.Add(i + 1);

                 newobj = newobj.AddNewField("item_" + i.ToString(), temp.ToArray());
              }

         }

     }

      public static class DynamicExtention
      {
          public static object AddNewField(this object obj, string key, object value)
          {
              JavaScriptSerializer js = new JavaScriptSerializer();

              string data = js.Serialize(obj);

              string newPrametr = "\"" + key + "\":" + js.Serialize(value);

              if (data.Length == 2)
             {
                 data = data.Insert(1, newPrametr);
              }
            else
              {
                  data = data.Insert(data.Length-1, ","+newPrametr);
              }

              return js.DeserializeObject(data);
          }
      }
   }
