Excel 在代码隐藏中将数据添加到 WorksheetPart

大家好，我正在使用以下代码创建一个包含 3 个工作表的 Excel 文件。

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();
            }

我需要知道如何填充 3 个数据表的单元格。我需要将字符串添加到可能位于某些数据表或多维数组中的某些单元格中。

private static void InsertValuesInWorksheet(WorksheetPart worksheetPart, IEnumerable<string> values)
{
    var worksheet = worksheetPart.Worksheet;
    var sheetData = worksheet.GetFirstChild<SheetData>();
    var row = new Row { RowIndex = 1 };  // add a row at the top of spreadsheet
    sheetData.Append(row);

    int i = 0;
    foreach (var value in values)
    {
        var cell = new Cell
                            {
                                CellValue = new CellValue(value),
                                DataType = new EnumValue<CellValues>(CellValues.String)
                            };

        row.InsertAt(cell, i);
        i++;
    }
}

此方法将向指定工作表添加新行，并使用数组中的值填充该行的单元格。在您的代码示例中，可以这样调用它：

var values = new[] {"foo", "bar", "baz"};

InsertValuesInWorksheet(newWorksheetPart1, values);
InsertValuesInWorksheet(newWorksheetPart2, values);
InsertValuesInWorksheet(newWorksheetPart3, values);
