如何通过C＃WPF更改Excel边框

Question

下面的代码已正确编译，但没有边框出现。

Microsoft.Office.Interop.Excel.Application app = new Microsoft.Office.Interop.Excel.Application();
  app.Visible = true;
  app.WindowState = XlWindowState.xlMaximized;
  Workbook wb = app.Workbooks.Add(XlWBATemplate.xlWBATWorksheet);
  Worksheet ws = wb.Worksheets[1];

  //BORDERS HERE
  ws.Range["A1:C5"].Borders.LineStyle = XlLineStyle.xlContinuous;
  ws.Range["A1:C5"].Borders[XlBordersIndex.xlEdgeTop].Weight = 10d;
  ws.Range["A1:C5"].Borders.ColorIndex = XlRgbColor.rgbCrimson;

感谢您的任何帮助

调用此范围的BeginUpdateFormatting方法，修改Borders并调用EndUpdateFormatting方法以完成修改。

Range range = ws.Range["A1:C5"];
Formatting rangeFormatting = range.BeginUpdateFormatting();
Borders rangeBorders = rangeFormatting.Borders;
rangeBorders.LineStyle = XlLineStyle.xlContinuous;
rangeBorders[XlBordersIndex.xlEdgeTop].Weight = 10d;
rangeBorders.ColorIndex = XlRgbColor.rgbCrimson;
range.EndUpdateFormatting(rangeFormatting);
