You can try this to convert object[] to double[]:

var res = (result as object[]).Select(x => (double)x).ToArray();

Correct way to handle this is

var res = (result as object[]).Select(x => Convert.ToDouble(x)).ToArray();

if all are double in object array than, alternative to above answer 

double[] resultArray = Array.ConvertAll<object, double>
                                  (inputArray, x => (double)x);
