Excel fügt Daten zu WorksheetPart im Code dahinter hinzu

Question

Hallo Leute, ich erstelle eine Excel-Datei mit 3 Arbeitsblättern mit folgendem Code.

using (SpreadsheetDocument spreadSheet = SpreadsheetDocument.Create(path + @"\UrlReport.xlsx", SpreadsheetDocumentType.Workbook))
            {
                // create the workbook
                spreadSheet.AddWorkbookPart();
                spreadSheet.WorkbookPart.Workbook = new DocumentFormat.OpenXml.Spreadsheet.Workbook();

                // CREATE FIRST SHEET
                WorksheetPart newWorksheetPart1 = spreadSheet.WorkbookPart.AddNewPart<WorksheetPart>();

                newWorksheetPart1.Worksheet = new DocumentFormat.OpenXml.Spreadsheet.Worksheet();

                // create sheet data
                newWorksheetPart1.Worksheet.AppendChild(new DocumentFormat.OpenXml.Spreadsheet.SheetData());

                // save worksheet
                newWorksheetPart1.Worksheet.Save();

                // create the worksheet to workbook relation
                spreadSheet.WorkbookPart.Workbook.AppendChild(new DocumentFormat.OpenXml.Spreadsheet.Sheets());
                spreadSheet.WorkbookPart.Workbook.GetFirstChild<DocumentFormat.OpenXml.Spreadsheet.Sheets>().AppendChild(new DocumentFormat.OpenXml.Spreadsheet.Sheet()
                {
                    Id = spreadSheet.WorkbookPart.GetIdOfPart(newWorksheetPart1),
                    SheetId = 1,
                    Name = "Sheet1"
                });

                //CREATE SECOND SHEET
                WorksheetPart newWorksheetPart2 = spreadSheet.WorkbookPart.AddNewPart<WorksheetPart>();
                newWorksheetPart2.Worksheet = new DocumentFormat.OpenXml.Spreadsheet.Worksheet();

                // create sheet data
                newWorksheetPart2.Worksheet.AppendChild(new DocumentFormat.OpenXml.Spreadsheet.SheetData());

                // save worksheet
                newWorksheetPart2.Worksheet.Save();

                // create the worksheet to workbook relation
                spreadSheet.WorkbookPart.Workbook.GetFirstChild<DocumentFormat.OpenXml.Spreadsheet.Sheets>().AppendChild(new DocumentFormat.OpenXml.Spreadsheet.Sheet()
                {
                    Id = spreadSheet.WorkbookPart.GetIdOfPart(newWorksheetPart2),
                    SheetId = 2,
                    Name = "Sheet2"

                });

                //CREATE THIRD SHEET
                WorksheetPart newWorksheetPart3 = spreadSheet.WorkbookPart.AddNewPart<WorksheetPart>();
                newWorksheetPart3.Worksheet = new DocumentFormat.OpenXml.Spreadsheet.Worksheet();

                // create sheet data
                newWorksheetPart3.Worksheet.AppendChild(new DocumentFormat.OpenXml.Spreadsheet.SheetData());

                // save worksheet
                newWorksheetPart3.Worksheet.Save();

                // create the worksheet to workbook relation
                spreadSheet.WorkbookPart.Workbook.GetFirstChild<DocumentFormat.OpenXml.Spreadsheet.Sheets>().AppendChild(new DocumentFormat.OpenXml.Spreadsheet.Sheet()
                {
                    Id = spreadSheet.WorkbookPart.GetIdOfPart(newWorksheetPart3),
                    SheetId = 3,
                    Name = "Sheet3"
                });

                spreadSheet.WorkbookPart.Workbook.Save();
            }

Ich muss wissen, wie ich die Zellen in den 3 Datenblättern ausfüllen kann. Ich muss nur Zeichenfolgen zu einigen Zellen hinzufügen, die wahrscheinlich in einer Datentabelle oder einem mehrdimensionalen Array sein werden.
