我使用 Microsoft.Office.Interop 将我的 DataGridView 导出到 Excel，但是我不愿意再使用 MS Office 并转向 LibreOffice 和 WPS。
我决定使用另一种方法（NetOfficeFW），并将原始代码修改为以下代码，以使用带有 .Net Framework 4.8 dev 的 NetOfficeFW 将我的 DataGridView 导出到 excel 中，
string time = DateTime.Now.ToString("dd-MM-yyyy");
Excel.Application app = new Excel.Application();
Excel.Workbook workbook = app.Workbooks.Add(Type.Missing);
//Make Worksheet Name
Excel.Worksheet worksheet = null;
//worksheet = workbook.ActiveSheet;
// worksheet = workbook.Sheets["Sheet1"];
worksheet.Name = "MySheetName-" + time;
worksheet.Range("A1", "M1").Interior.Color = XlRgbColor.rgbGrey;
worksheet.Range("A1", "M1").Font.Color = XlRgbColor.rgbWhite;
//Set Colum width
app.Columns.AutoFit();
app.Columns.ColumnWidth = 14;
app.Columns[1].Hidden = true;
app.Columns[2].Hidden = true;
app.Columns[3].ColumnWidth = 13;
app.Columns[4].ColumnWidth = 15;
app.Columns[5].ColumnWidth = 9;
app.Columns[6].ColumnWidth = 9;
app.Columns[7].ColumnWidth = 9;
app.Columns[8].ColumnWidth = 9;
app.Columns[9].ColumnWidth = 9;
app.Columns[10].ColumnWidth = 9;
app.Columns[11].ColumnWidth = 9;
app.Columns[12].ColumnWidth = 9;
app.Columns[13].ColumnWidth = 9;
app.Columns[14].ColumnWidth = 25;
////TextAlignment
app.Columns[3].HorizontalAlignment = XlHAlign.xlHAlignLeft;
app.Columns[4].HorizontalAlignment = XlHAlign.xlHAlignCenter;
app.Columns[5].HorizontalAlignment = XlHAlign.xlHAlignCenter;
app.Columns[6].HorizontalAlignment = XlHAlign.xlHAlignCenter;
app.Columns[7].HorizontalAlignment = XlHAlign.xlHAlignCenter;
app.Columns[8].HorizontalAlignment = XlHAlign.xlHAlignCenter;
app.Columns[9].HorizontalAlignment = XlHAlign.xlHAlignCenter;
app.Columns[10].HorizontalAlignment = XlHAlign.xlHAlignCenter;
app.Columns[11].HorizontalAlignment = XlHAlign.xlHAlignCenter;
app.Columns[12].HorizontalAlignment = XlHAlign.xlHAlignCenter;
app.Columns[13].HorizontalAlignment = XlHAlign.xlHAlignCenter;
//Set Header & Footer
ckconnection.getGeneralSetting();
worksheet.PageSetup.LeftHeader = "&\"Calibri\"&14&K8B2252" + DEVELOPER NAME;
worksheet.PageSetup.CenterHeader = "&\"Calibri\"&14&K8B2252 REPORT NAME";
worksheet.PageSetup.RightHeader = "&\"Calibri\"&14&K8B2252" + company_name;
worksheet.PageSetup.CenterFooter = "&[Page] of &[Pages]";
worksheet.PageSetup.RightFooter = time;
//Page size and layout
worksheet.PageSetup.Orientation = XlPageOrientation.xlLandscape;
worksheet.PageSetup.PaperSize = XlPaperSize.xlPaperA4;
// Narrow Margins
worksheet.PageSetup.LeftMargin = app.InchesToPoints(0.25);
worksheet.PageSetup.RightMargin = app.InchesToPoints(0.25);
worksheet.PageSetup.TopMargin = app.InchesToPoints(0.75);
worksheet.PageSetup.BottomMargin = app.InchesToPoints(0.75);
worksheet.PageSetup.HeaderMargin = app.InchesToPoints(0.3);
worksheet.PageSetup.FooterMargin = app.InchesToPoints(0.3);
for (int i = 1; i < gridView.Columns.Count + 1; i++)
{
Excel.Range xlRange = (Excel.Range)app.Cells[1, i];
xlRange.Font.Bold = -1;
xlRange.Borders.LineStyle = XlLineStyle.xlContinuous;
xlRange.Borders.Weight = 1d;
xlRange.HorizontalAlignment = XlHAlign.xlHAlignCenter;
app.Cells[1, i] = gridView.Columns[i - 1].HeaderText;
}
for (int i = 0; i < gridView.Rows.Count; i++)
{
for (int j = 0; j < gridView.Columns.Count; j++)
{
Excel.Range xlRange = (Excel.Range)app.Cells[i + 2, j + 1];
xlRange.Borders.LineStyle = XlLineStyle.xlContinuous;
xlRange.Borders.Weight = 1d;
app.Cells[i + 2, j + 1] = gridView.Rows[i].Cells[j].Value.ToString();
}
}
var saveFileDialoge = new SaveFileDialog();
saveFileDialoge.FileName = "MySheetName-" + time + ".xlsx";
if (saveFileDialoge.ShowDialog() == DialogResult.OK)
{
app.ActiveWorkbook.SaveAs(saveFileDialoge.FileName);
}
app.Quit();
不幸的是，以下两行中有一个突出显示的错误：
app.Cells[1, i] = gridView.Columns[i - 1].HeaderText;
app.Cells[i + 2, j + 1] = gridView.Rows[i].Cells[j].Value.ToString();
错误文本是：
无法将字符串转换为 NetOffice.Excel.Api.Range
我该如何解决这个问题？
