如何在C＃中的Excel範圍中添加底部邊框？

Question

我需要爲電子表格上的某些行添加底部邊框（簡單的實線）。我有我需要定義工作範圍，但嘗試添加邊框代碼都失敗了，因爲可以通過註釋掉的嘗試中可以看出：

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? 
} 

哪個對象的屬性或方法做我需要做的幽會到或打電話，以及如何？

Answer 1

這個工作對我來說：

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; 
} 

Answer 2

試試這個：

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; 
    } 

要清除邊框你可以使用：

border.LineStyle = XlConstants.xlNone 

對於邊界體重，你可能想.xlThin

邊框重量：

對於其他行樣式選項，你可以試試（我沒試過這些）：

這裏是我使用的語句（你不需要所有這些）：

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;
