如何在C＃中向Excel范圍添加底部邊框？

Question

我需要在電子表格的某些行上添加底邊框（一條簡單的實線）。 我已經定義了所需的范圍，但是添加邊界代碼的嘗試失敗了，如注釋掉的嘗試所示：

private ApplicationClass _xlApp;
private Workbook _xlBook;
private Sheets _xlSheets;
private Worksheet _xlSheet;
. . .
private void AddBottomBorder(int rowToBottomBorderize)
{
    var rangeToBottomBorderize = (Range)_xlSheet.Cells[rowToBottomBorderize, TOTALS_COL];
    //rangeToBottomBorderize.Borders[_xlApp.XlBordersIndex.xlEdgeBottom] = 
    //rangeToBottomBorderize.Borders[XlBordersIndex.xlEdgeBottom] = 1d;
    //rangeToBottomBorderize.Borders[_xlSheet.
    //_xlSheet.Cells[rowToBottomBorderize, TOTALS_COL].Borders[Excel.XlBordersIndex.xlEdgeBottom].Weight = 1d;
   // someRange.Borders.Item[XlBordersIndex.xlEdgeBottom)] = ...what now?
}

我需要為哪個對象的屬性或方法進行分配或調用，以及如何分配？

Answer 1

嘗試這個：

setBorder( rangeToBottomBorderize.Borders[_xlApp.XlBordersIndex.xlEdgeBottom], XlBorderWeight.xlThick );

輔助功能：

  private static void setBorder( Border border, XlBorderWeight borderWeight )
  {
     border.LineStyle = XlLineStyle.xlContinuous;
     border.ColorIndex = XlConstants.xlAutomatic;
     border.TintAndShade = 0;
     border.Weight = borderWeight;
  }

要清除邊框，您可以使用：

border.LineStyle = XlConstants.xlNone

對於邊框粗細，您可能需要.xlThin

邊框重量：

對於其他線型選項，您可以嘗試（我還沒有嘗試過）：

這是我的using語句（您不需要所有這些）：

using Microsoft.Office.Interop.Word;
using Microsoft.Office.Interop.Excel;
using Application = Microsoft.Office.Interop.Excel.Application;
using Border = Microsoft.Office.Interop.Excel.Border;
using Range = Microsoft.Office.Interop.Excel.Range;
using XlBorderWeight = Microsoft.Office.Interop.Excel.XlBorderWeight;
using XlLineStyle = Microsoft.Office.Interop.Excel.XlLineStyle;
using XlConstants = Microsoft.Office.Interop.Excel.Constants;

Answer 2

這對我有用：

private void AddBottomBorder(int rowToBottomBorderize)
{
    var rowToBottomBorderizeRange = _xlSheet.Range[_xlSheet.Cells[rowToBottomBorderize, ITEMDESC_COL], _xlSheet.Cells[rowToBottomBorderize, TOTALS_COL]];
    Borders border = rowToBottomBorderizeRange.Borders;
    border[XlBordersIndex.xlEdgeBottom].LineStyle = XlLineStyle.xlContinuous;
}
