Aggiungere nuovi fogli di lavoro a un cartella di lavoro e attivare un foglio in VSTO e Aspose.Cells

Suggerimento per la migrazione:

1. Aggiungi nuovi fogli di lavoro a un file esistente di Microsoft Excel.
2. Riempire i dati nelle celle di ogni nuovo foglio di lavoro.
3. Attiva un foglio di lavoro nel workbook.
4. Salvare come file di Microsoft Excel.

Qui sotto sono riportati frammenti di codice paralleli per VSTO (C#) e Aspose.Cells for .NET (C#), che mostrano come eseguire queste attività.

VSTO

 //intiate application object

Excel.Application excelApp = Application;

//Specify the template excel file path.

string myPath = "Book1.xls";

//Open the excel file.

excelApp.Workbooks.Open(myPath, Missing.Value, Missing.Value,

Missing.Value, Missing.Value,

Missing.Value, Missing.Value,

Missing.Value, Missing.Value,

Missing.Value, Missing.Value,

Missing.Value, Missing.Value,

Missing.Value, Missing.Value);

//Declare a Worksheet object.

Excel.Worksheet newWorksheet;

//Add 5 new worksheets to the workbook and fill some data

//into the cells.

for (int i = 1; i < 6; i++){

                //Add a worksheet to the workbook.

                newWorksheet = (Excel.Worksheet)excelApp.Worksheets.Add(Missing.Value, Missing.Value,

                Missing.Value, Missing.Value);

                //Name the sheet.

                newWorksheet.Name = "New_Sheet" + i.ToString();

                //Get the Cells collection.

                Excel.Range cells = newWorksheet.Cells;

                //Input a string value to a cell of the sheet.

                cells.set_Item(i, i, "New_Sheet" + i.ToString());

            }

//Activate the first worksheet by default.

((Excel.Worksheet)excelApp.ActiveWorkbook.Sheets[1]).Activate();

//Save As the excel file.

excelApp.ActiveWorkbook.SaveCopyAs("out_Book1.xls");

//Quit the Application.

excelApp.Quit();

Aspose.Cells

 //Instantiate an instance of license and set the license file

//through its path

Aspose.Cells.License license = new Aspose.Cells.License();

license.SetLicense("Aspose.Total.lic");

//Specify the template excel file path.

string myPath = "Book1.xls";

//Instantiate a new Workbook.

//Open the excel file.

Workbook workbook = new Workbook(myPath);

//Declare a Worksheet object.

Worksheet newWorksheet;

//Add 5 new worksheets to the workbook and fill some data

//into the cells.

for (int i = 0; i < 5; i++){

                //Add a worksheet to the workbook.

                newWorksheet = workbook.Worksheets[workbook.Worksheets.Add()];

                //Name the sheet.

                newWorksheet.Name = "New_Sheet" + (i + 1).ToString();

                //Get the Cells collection.

                Cells cells = newWorksheet.Cells;

                //Input a string value to a cell of the sheet.

                cells[i, i].PutValue("New_Sheet" + (i + 1).ToString());

            }

//Activate the first worksheet by default.

workbook.Worksheets.ActiveSheetIndex = 0;

//Save As the excel file.

workbook.Save("out_My_Book1.xls");
