Добавление новых рабочих листов в книгу и активация листа в VSTO и Aspose.Cells

Совет по миграции:

1. Добавьте новые листы в существующий файл Microsoft Excel.
2. Заполните данные в ячейки каждого нового листа.
3. Активируйте лист в рабочей книге.
4. Сохраните как файл Microsoft Excel.

Ниже приведены параллельные фрагменты кода для VSTO (C#) и Aspose.Cells for .NET (C#), которые показывают, как выполнить эти задачи.

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");
