long record insert into Access using c#

Hi, I have a long record i'm trying to add to access using c#

but when I use the table.rows.add using an object it fails at the bottom,

The data in the array lines up with my columns in the datatable, although I'm not 100% confident I'm handling the autoincrement ID in the first field. I'm using "null" bc I'm expecting the database to generate it.

Can you help?

private static DataRow addDR(DataTable prtab, double[] dtAr, int[] CrvID, Int64 sims, double[,] crNs, int rNum)

            int ln = dtAr.Length;
            object[] arr = new object[ln+2];
                for (int j = 0; j < ln + 2; j++)
                    if (j == 0)
                        arr[j] = null;
                    else if (j == 1)
                        arr[j] = rNum;
                        arr[j] = crNs[rNum, j - 2];
            prtab.Rows.Add(arr);  fails here

            return prtab.Rows.Add(arr);
