如何使用C＃有效地將右邊框添加到Excel范圍？

Question

是否有一種簡潔的（單行）方法，可以使用C＃以編程方式向Excel電子表格上的一系列單元格添加右邊界？

此代碼有效：

private void AddRightBorderToMainRange()
{
    for (int i = COLUMN_HEADING_ROW; i < _lastRowAdded; i++)
    {
        for (int j = ITEMDESC_COL; j < TOTALS_COL; j++)
        {
            var rightBorderizeRange = _xlSheet.Range[_xlSheet.Cells[i, j], _xlSheet.Cells[i, j]];
            Borders border = rightBorderizeRange.Borders;
            border[XlBordersIndex.xlEdgeRight].LineStyle = XlLineStyle.xlContinuous;
        }
    }
}

...（外部覆蓋行范圍的循環，內部覆蓋列范圍的循環），但看起來過於矯kill，可能效率不高。

這樣會更有效，也不會引起多視。

var rightBorderizeRange = 
    _xlSheet.Range[_xlSheet.Cells[COLUMN_HEADING_ROW, ITEMDESC_COL], 
    _xlSheet.Cells[_lastRowAdded, TOTALS_COL]];
Borders border = rightBorderizeRange.Borders;
border[XlBordersIndex.xlInsideVertical].LineStyle =
    XlLineStyle.xlContinuous;

所以需要做的是：

0) Define the range you want to operate on (add right borderlines to) - named *rightBorderizeRange* above
1) Get the Borders member for that range - named *border* above
2) Apply a border to the InsideVertical (vertical lines within that range) member of the border array
