c# Aspose.Cells 通過Excel模板生產excel數據再打印

多的不說，我們先來利用Northwind做兩個小demo。先說說Aspose.Cells的模板語法：

1. &=DataSource.Field，&=[DataSource].[Field]是對DataTable和幾何類型的引用，將會從當前行開始豎直向下生成多行數據。
2. &=$data:是對變量或數組的引用。數組存在skip，horizontal等屬性，具體參見
   
3. &=&=動態公式計算；{r}當前行，{c}當前列，{-n}，{n}當前行或列的偏移量前n或后n。
4. &==是動態計算，如excel，if等語句。（if（logic_test,true_value,false_value））

還有其他更為復雜的匯總計算的表達式，這里也不在這節多講，有興趣的朋友，可以去官網看看。我們先來個簡單的例子，光說，總是不行的，還是要代碼實踐才能說明一切：

代碼如下：

App_Code.SqlDbHelper help = new App_Code.SqlDbHelper();
var s = Aspose.Cells.CellsHelper.GetVersion();
var sql = "select WL_TZ,WL_CL,RPCJH_SL,WL_MC,RPCJH_JHKGRQ,RPCJH_JHID,RPCJH_JHID as RPCJH_JHID1,RPCJH_GXID,U_RPCJH_KH,(select rtrim((cast(GYLX_GXID as char(2)))+' '+ltrim(GYLX_GXMC)) from GYLX where GYLX_GYLXID=wo.WO_GYLXID and GYLX_GXID=RPCJH_GXID) as gxmc from RPCJH left join wl on RPCJH_WLID=WL_WLID left join wo on wo.WO_WOID=RPCJH_WOID where RPCJH_JHID='JHA1909152' and RPCJH_BZGXID!='888' ";
var dt = help.ExecuteDataTable(sql);
dt.TableName = "Customers";
Workbook workBook = new Workbook(@"E:\KaBoProject\GTDB\GTDB\bin\Debug\機加作業計划卡.xls");
WorkbookDesigner designer = new WorkbookDesigner(workBook);
//數據源
designer.SetDataSource(dt);
//報表單位
designer.SetDataSource("RPCJH_JHID", dt.Rows[0]["RPCJH_JHID"].ToString().Trim());
designer.SetDataSource("U_RPCJH_KH", dt.Rows[0]["U_RPCJH_KH"].ToString().Trim());
designer.SetDataSource("RPCJH_JHID1", "計划編號：" + dt.Rows[0]["RPCJH_JHID1"].ToString().Trim() + " 領卡人：");
designer.SetDataSource("RPCJH_JHKGRQ", "派工日期:" +Convert.ToDateTime(dt.Rows[0]["RPCJH_JHKGRQ"].ToString().Trim()).ToShortDateString());
designer.SetDataSource("WL_MC", "名稱：" + dt.Rows[0]["WL_MC"].ToString().Trim());
designer.SetDataSource("WL_TZ", dt.Rows[0]["WL_TZ"].ToString().Trim());
designer.SetDataSource("WL_CL", dt.Rows[0]["WL_CL"].ToString().Trim());
designer.SetDataSource("RPCJH_SL", dt.Rows[0]["RPCJH_SL"].ToString().Trim());

designer.Process();
workBook.Save(@"E:\KaBoProject\GTDB\GTDB\bin\Debug\2.xls", SaveFormat.Xlsx);

designer = null;

生成的excel如下

打印代碼如下：

Workbook workbook = new Workbook(@"E:\KaBoProject\GTDB\GTDB\bin\Debug\2.xls");
           
            //Get the worksheet to be printed
Worksheet worksheet = workbook.Worksheets[0];//獲取該Excel文檔的第一個工作表
            //PageSetup pageSetup = worksheet.PageSetup;
            //pageSetup.Orientation = PageOrientationType.Landscape;
            //pageSetup.LeftMargin = 0;
            //pageSetup.RightMargin = 0.1;          
            //pageSetup.BottomMargin = 0.3;
            //pageSetup.PrintArea = "A2:J29";
            //Apply different Image / Print options.
            Aspose.Cells.Rendering.ImageOrPrintOptions options = new Aspose.Cells.Rendering.ImageOrPrintOptions();

            //Set the Printing page property
            //options.PrintingPage = PrintingPageType.IgnoreStyle;
            //Render the worksheet
            SheetRender sr = new SheetRender(worksheet, options);

            System.Drawing.Printing.PrinterSettings printSettings = new System.Drawing.Printing.PrinterSettings();
            string strPrinterName = printSettings.PrinterName;

            //send to printer
            //System.Drawing.Image map = sr.ToImage(0);

            sr.ToPrinter(strPrinterName);
