如何有效地向C＃中的Excel範圍添加正確的邊框？

Question

是否有一種簡潔（單行）的方式，以編程方式將正確邊框添加到使用C＃的Excel電子表格上的一組單元格中？

此代碼：

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for循環覆蓋範圍的行，內環覆蓋範圍列），但似乎矯枉過正，可能效率低下。

Answer 1

這一點更有效和更crosseye誘導：

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; 

所以需要做什麼：

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
