For those who use SpecialCells method, (I'm not sure about others), Please Note in case your last cell is merged, you won't be able to get last row and column number using Range.Row and Range.Column to get the last row and column as numbers. you need to first Unmerge your range and then Again get the last cell. It cost me a lot.

private int[] GetLastRowCol(Ex.Worksheet ws)
    {
        Ex.Range last = ws.Cells.SpecialCells(Ex.XlCellType.xlCellTypeLastCell, Type.Missing);
        bool isMerged = (bool)last.MergeCells;
        if (isMerged)
        {
            last.UnMerge();
            last = ws.Cells.SpecialCells(Ex.XlCellType.xlCellTypeLastCell, Type.Missing);
        }
        return new int[2] { last.Row, last.Column };
    }
