aspose.cell 實現通過excel模板導出具有多個sheet的excel

            //打開excel模板
            Workbook workbook = new Workbook("D:/1.xlsx");
            //打開設計器
            WorkbookDesigner designer = new WorkbookDesigner(workbook);
            //選擇excel中的第一個sheet作為模板
            Worksheet worksheet = workbook.Worksheets[0];
            //copy模板並添加一個新的sheet
            int index = workbook.Worksheets.AddCopy(0);
            Worksheet destSheet = workbook.Worksheets[index];
            //設置單元格區域
            Range sourceRange = worksheet.Cells.MaxDisplayRange;
            //創建行數和列數與源工作表相同的區域
            Range destRange = destSheet.Cells.CreateRange(sourceRange.FirstRow, sourceRange.FirstColumn, sourceRange.RowCount, sourceRange.ColumnCount);
            //粘貼
            PasteOptions options = new PasteOptions();
            options.PasteType = PasteType.All;
            //從源工作表復制到目標工作表。
            destRange.Copy(sourceRange, options);
            //指定要修改的sheet
            designer.Process(index, true);
            //保存
            workbook.Save("D:/2.xlsx");
