无法使用EPPlus C#将数据从Datagridview插入到Excel

ExcelPackage excelPackage = new ExcelPackage();

ExcelWorksheet worksheet = excelPackage.Workbook.Worksheets.Add("Sheet1"); // 创建一个名为Sheet1的工作表
// 或者
ExcelWorksheet worksheet = excelPackage.Workbook.Worksheets["Sheet1"]; // 获取名为Sheet1的工作表

for (int row = 0; row < dataGridView.Rows.Count; row++)
{
    for (int col = 0; col < dataGridView.Columns.Count; col++)
    {
        worksheet.Cells[row + 1, col + 1].Value = dataGridView.Rows[row].Cells[col].Value;
    }
}

excelPackage.SaveAs(new FileInfo("path/to/save/excel.xlsx"));
