Formula not calculating with EPPLUS

Question

I would like to transfer a Datatableto excel and calculate a sum. For this I\'m using epplus. Here is my code:

Sheet.Cells[\"A1\"].LoadFromDataTable         


        

Answer 1

After searching long time it seems that epplus ignores the datatype if I use .LoadFromDataTable and write every value as string. So I have to parse every value to double and write it back into the cells. After that everything is running fine.

double ZahlAlsText;
        for (int i = 2; i < totalCols; i++) 'columns
        {
            for (int y = 2; y <= letztezeile + 1; y++) 'rows
            {
                ZahlAlsText = double.Parse(range[y, i].Value.ToString());
                range[y, i].Style.Numberformat.Format = "#,##0.00";
                range[y, i].Value = ZahlAlsText;
            }
        }
