c# - 更改Excel中的左，右，下和上边框

Question

首先，我将工作表的颜色边框更改为白色，因为我想要一张白色的工作表。

然后我做了一些标题并想在它周围做一个边框。问题是它在标题中的值之间设置了边界，但顶部、向下不可见。

我的代码：

xlWorkSheet5.Columns.Borders.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.White); // Color Sheet5 to white, BusLoad
xlWorkSheet5.Columns.NumberFormat = "@";

Excel.Range rng = (Excel.Range)xlWorkSheet5.get_Range("A7","J7");
rng.RowHeight = 25.5;

rng.BorderAround2(Excel.XlLineStyle.xlContinuous, Excel.XlBorderWeight.xlHairline, Excel.XlColorIndex.xlColorIndexAutomatic, Excel.XlColorIndex.xlColorIndexAutomatic);
rng.Borders.LineStyle = Excel.XlLineStyle.xlContinuous;
rng.Borders.Weight = 1d;

rng.Font.Bold = true;
rng.HorizontalAlignment = Microsoft.Office.Interop.Excel.XlHAlign.xlHAlignCenter;
rng.Interior.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.LightGray); 

Answer 1

好的，我找到了解决方案，这是我的代码：

xlWorkSheet5.Cells[7,1].Borders[Excel.XlBordersIndex.xlEdgeLeft].Weight = 1d;
xlWorkSheet5.Cells[7, 1].Borders[Excel.XlBordersIndex.xlEdgeRight].Weight = 1d;
xlWorkSheet5.Cells[7,1].Borders[Excel.XlBordersIndex.xlEdgeTop].Weight = 1d;
xlWorkSheet5.Cells[7,1].Borders[Excel.XlBordersIndex.xlEdgeBottom].Weight = 1d;

Answer 2

如果您想使用 Borders[index] 属性，请使用以下内容：

rng.Borders[XlBordersIndex.xlEdgeLeft].LineStyle = XlLineStyle.xlContinuous;
rng.Borders[XlBordersIndex.xlEdgeLeft].ColorIndex = <COLOR THAT YOU WANT>

rng.Borders[XlBordersIndex.xlEdgeTop]...
rng.Borders[XlBordersIndex.xlEdgeBottom]...
rng.Borders[XlBordersIndex.xlEdgeRight]...

Answer 3

Border.Weight 属性

XlBorderWeight 可以是以下 XlBorderWeight 常量之一：xlHairline xlThin xlMedium xlThick。

在单元格上创建从 Bx 到 Mx 的连续线的示例，其中 x 是行数

using Excel = Microsoft.Office.Interop.Excel;

Excel.Range line = (Excel.Range)excelWorksheet.Rows[1]; 
line.Insert();

excelWorksheet.Range[$"B{1}:M{1}"].Cells.Borders[Excel.XlBordersIndex.xlEdgeBottom].LineStyle = Excel.XlLineStyle.xlContinuous;
excelWorksheet.Range[$"B{1}:M{1}"].Cells.Borders[Excel.XlBordersIndex.xlEdgeBottom].Weight = Excel.XlBorderWeight.xlThin;
