c#，Microsoft Interop Excel，更改所选范围的字体样式

Question

我需要更改Excel工作表中某些单元格的字体样式(字体类型)。 Excel工作表由Microsoft.Office.Interop.Excel生成

我想将 B3 到 B100 范围更改为 Arial 字体类型。 这是我的代码

Microsoft.Office.Interop.Excel._Application app = new Microsoft.Office.Interop.Excel.Application();
Microsoft.Office.Interop.Excel._Workbook workbook = app.Workbooks.Add(Type.Missing);
Microsoft.Office.Interop.Excel._Worksheet worksheet = null;

app.Visible = true;
worksheet = workbook.Sheets["Sheet1"];
worksheet = workbook.ActiveSheet;
worksheet.Name = "Exported from gridview";
worksheet.get_Range("B3", "B100").Cells.Font.FontStyle = "Arial";

for (int i = 1; i < records_datagridview.Columns.Count + 1; i++)
{
   worksheet.Cells[1, i] = records_datagridview.Columns[i - 1].HeaderText;
}

for (int i = 0; i < records_datagridview.Rows.Count; i++)
{
   for (int j = 0; j < records_datagridview.Columns.Count; j++)
   {
      worksheet.Cells[i + 2, j + 1] = records_datagridview.Rows[i].Cells[j].Value.ToString();
   }
}

String file_path = fbd.SelectedPath + "/records_sheet_" + DateTime.Now.ToString("yyyy-MM-dd-HH-mm-ss") + "_.xlsx";

workbook.SaveAs(file_path, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
                Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive,
                Type.Missing, Type.Missing, Type.Missing, Type.Missing);

app.Quit();

我用过

worksheet.get_Range("B3", "B4").Cells.Font.FontStyle = "Arial";

但是没有效果 谁能帮我解决这个问题

把你的代码改成这样:

worksheet.get_Range("B3", "B4").Cells.Font.Name = "Arial";

提示:在许多情况下，您可以自己回答此类问题:只需录制一个 Excel 宏并查看生成的代码。即使它是 VBA，而不是 C#，您也会经常看到您需要的东西。
