我正在尝试使用OpenXML创建一个xlsx格式的Excel文件，因为我需要在Web服务器上使用它。
我可以填充工作表中的值，但是我无法将经典日期格式设置在单元格中。
下面是使用DocumentFormat.OpenXml和WindowsBase引用进行的快速测试。
class Program
{
static void Main(string[] args)
{
BuildExel(@"C:\test.xlsx");
}
public static void BuildExel(string fileName)
{
using (SpreadsheetDocument myWorkbook =
SpreadsheetDocument.Create(fileName,
SpreadsheetDocumentType.Workbook))
{
// Workbook Part
WorkbookPart workbookPart = myWorkbook.AddWorkbookPart();
var worksheetPart = workbookPart.AddNewPart<WorksheetPart>();
string relId = workbookPart.GetIdOfPart(worksheetPart);
// File Version
var fileVersion = new FileVersion { ApplicationName = "Microsoft Office Excel" };
// Style Part
WorkbookStylesPart wbsp = workbookPart.AddNewPart<WorkbookStylesPart>();
wbsp.Stylesheet = CreateStylesheet();
wbsp.Stylesheet.Save();
// Sheets
var sheets = new Sheets();
var sheet = new Sheet { Name = "sheetName", SheetId = 1, Id = relId };
sheets.Append(sheet);
// Data
SheetData sheetData = new SheetData(CreateSheetData1());
// Add the parts to the workbook and save
var workbook = new Workbook();
workbook.Append(fileVersion);
workbook.Append(sheets);
var worksheet = new Worksheet();
worksheet.Append(sheetData);
worksheetPart.Worksheet = worksheet;
worksheetPart.Worksheet.Save();
myWorkbook.WorkbookPart.Workbook = workbook;
myWorkbook.WorkbookPart.Workbook.Save();
myWorkbook.Close();
}
}
private static Stylesheet CreateStylesheet()
{
Stylesheet ss = new Stylesheet();
var nfs = new NumberingFormats();
var nformatDateTime = new NumberingFormat
{
NumberFormatId = UInt32Value.FromUInt32(1),
FormatCode = StringValue.FromString("dd/mm/yyyy")
};
nfs.Append(nformatDateTime);
ss.Append(nfs);
return ss;
}
private static List<OpenXmlElement> CreateSheetData1()
{
List<OpenXmlElement> elements = new List<OpenXmlElement>();
var row = new Row();
// Line 1
Cell[] cells = new Cell[2];
Cell cell1 = new Cell();
cell1.DataType = CellValues.InlineString;
cell1.InlineString = new InlineString { Text = new Text { Text = "Daniel" } };
cells[0] = cell1;
Cell cell2 = new Cell();
cell2.DataType = CellValues.Number;
cell2.CellValue = new CellValue((50.5).ToString());
cells[1] = cell2;
row.Append(cells);
elements.Add(row);
// Line 2
row = new Row();
cells = new Cell[1];
Cell cell3 = new Cell();
cell3.DataType = CellValues.Date;
cell3.CellValue = new CellValue(DateTime.Now.ToOADate().ToString());
cell3.StyleIndex = 1; // <= here I try to apply the style...
cells[0] = cell3;
row.Append(cells);
elements.Add(row);
return elements;
}
cell3.StyleIndex = 1;
我可以打开这个文件，但是日期没有格式化，只有日期的数字。
感谢您帮忙格式化日期。
