New Post: 修改xlsx文件后保存会丢失数据和格式

OpenFileDialog dialog = new OpenFileDialog();
            dialog.Filter = "excel file *.xlsx|*.xlsx";

            if (dialog.ShowDialog() == DialogResult.Cancel)
            {
                return;
            }

            FileStream fileStream = new FileStream(dialog.FileName, FileMode.Open, FileAccess.Read);
            IWorkbook workbook = WorkbookFactory.Create(fileStream);

            ISheet ProcessSheet = workbook.GetSheet("sheet1");

            ProcessSheet.ShiftRows(9, ProcessSheet.LastRowNum, 10, true, false);

            SaveFileDialog saveDialog = new SaveFileDialog();
            saveDialog.Filter = "Excel file *.xlsx|*.xlsx";
            if (saveDialog.ShowDialog() == DialogResult.Cancel)
                return;

            FileStream WirteStream = new FileStream(saveDialog.FileName, FileMode.OpenOrCreate, FileAccess.Write);
            workbook.Write(WirteStream);
            WirteStream.Close();
            fileStream.Close();
