如何在C＃中使用OPEN XML创建具有多个工作表的Excel文件

Question

对不起，我的英语。我是OPEN XML SDK的新手。 我的问题是：如何创建具有多个工作表的Excel文件。 亲切地

我的示例代码：

public void CreateExcelDoc(string fileName)
{
    using (SpreadsheetDocument document = SpreadsheetDocument.Create(fileName, SpreadsheetDocumentType.Workbook))
    {
        WorkbookPart workbookPart = document.AddWorkbookPart();
        workbookPart.Workbook = new Workbook();
        Sheets sheets = workbookPart.Workbook.AppendChild(new Sheets());
        int i = 0;
        for (i = 0; i < 3; i++)
        {
            WorksheetPart worksheetPart = workbookPart.AddNewPart();
            worksheetPart.Worksheet = new Worksheet();
            Sheet sheet = new Sheet() { Id = workbookPart.GetIdOfPart(worksheetPart), SheetId = Convert.ToUInt32(i), Name = "Employees" + i.ToString() };
            sheets.Append(sheet);
            workbookPart.Workbook.Save();
            List<Employee> employees = Employees.EmployeesList;

            SheetData sheetData = worksheetPart.Worksheet.AppendChild(new SheetData());

            // Constructing header
            Row row = new Row();
            row.Append(
                ConstructCell("Id", CellValues.String),
                ConstructCell("Name", CellValues.String),
                ConstructCell("Birth Date", CellValues.String),
                ConstructCell("Salary", CellValues.String));
            // Insert the header row to the Sheet Data
            sheetData.AppendChild(row);

            // Inserting each employee
            foreach (var employee in employees)
            {
                row = new Row();

                row.Append(
                    ConstructCell(employee.Id.ToString(), CellValues.Number),
                    ConstructCell(employee.Name, CellValues.String),
                    ConstructCell(employee.DOB.ToString("yyyy/MM/dd"), CellValues.String),
                    ConstructCell(employee.Salary.ToString(), CellValues.Number));
                sheetData.AppendChild(row);
            }

            worksheetPart.Worksheet.Save();

        }
    }
}
private Cell ConstructCell(string value, CellValues dataType)
{
    return new Cell()
    {
        CellValue = new CellValue(value),
        DataType = new EnumValue<CellValues>(dataType)
    };
}
