as following

public class herelist {     public list<list<double>> values { get; set; }     public string type { get; set; } }

can guide how extract values ([[a,b],[c,d]]) single list here.

tried thing 

herelist ge = new herelist();         var x = ge.values;          foreach(var val in x)//[13.38,52.51]         {            //pupulate list<double> //[13.38,52.51]         }
