对于二进制存十进制数转化

public static List<string> GetListByBinary(int? org)
        {
            List<string> list = new List<string>();
            try
            {
                string dec = System.Convert.ToString(org.Value, 2);
                char[] arr = dec.ToCharArray();
                System.Array.Reverse(arr);
                for (int i = 0; i < arr.Length; i++)
                {
                    if (arr[i] == ‘1‘)
                    {
                        double fanDec = System.Math.Pow(2, i);
                        list.Add(System.Convert.ToString(fanDec));
                    }
                }
            }
            catch
            {
            }
            return list;
