[我使用Microsoft.Office.Interop将DataGridView导出到Excel，但是我不再愿意使用MS Office并转移到LibreOffice和WPS。
我决定使用替代方法（NetOfficeFW），并将原始代码修改为以下代码，以将NetGridFW与.Net Framework 4.8 dev一起使用，将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.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();
错误文本为：
无法将字符串转换为NetOffice.Excel.Api.Range
我该如何解决此问题？
实际上，我没有从NetOffice的开发人员那里获得任何支持，所以我转而使用ClosedXML，它确实很容易使用。这是无需安装MS Office即可与我一起使用的代码...使用ClosedXML
//Creating DataTable.
DataTable dt = new DataTable();
//Adding the Columns.
foreach (DataGridViewColumn column in gridView.Columns)
{
dt.Columns.Add(column.HeaderText, typeof(string));
}
//Adding the Rows.
foreach (DataGridViewRow row in gridView.Rows)
{
dt.Rows.Add();
foreach (DataGridViewCell cell in row.Cells)
{
dt.Rows[dt.Rows.Count - 1][cell.ColumnIndex] = cell.Value.ToString();
}
}
//Exporting to Excel
using (XLWorkbook workbook = new XLWorkbook())
{
string time = DateTime.Now.ToString("dd-MM-yyyy");
// add a new Workbook and worksheet
var worksheet = workbook.Worksheets.Add(dt, "SheetName-" + time);
