如何在 C# 中为 Excel 范围添加底部边框？

Question

我需要在电子表格的某些行中添加底部边框（一条简单的实线）。我已经定义了我需要使用的范围，但是添加边框代码的尝试失败了，正如注释掉的尝试所示：

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?
}

我需要对哪些对象的属性或方法进行赋值或调用，如何进行？

Answer 1

试试这个：

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

辅助函数：

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

要清除边框，您可以使用：

border.LineStyle = XlConstants.xlNone

对于边框粗细，您可能需要 .xlThin

边框重量：

对于其他线型选项，您可以尝试（我没有尝试过这些）：

https://msdn.microsoft.com/en-us/library/microsoft.office.interop.excel.border.linestyle.aspx

这是我的使用语句（你不需要所有这些）：

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

这对我有用：

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;
}
