我正在嘗試使用OpenXML以xlsx格式創建Excel文件，因爲我需要在Web服務器上使用它。Excel中的OpenXml和日期格式單元格
我沒有任何問題來填充表中的值;但我很努力在單元格中設置經典日期格式。
下面的快速測試使用DocumentFormat.OpenXml和WindowsBase參考。
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;
}
執行的代碼創建Excel文檔。但是，當我嘗試打開文檔時，我收到以下消息：「Excel在'test.xlsx'中發現了不可讀的內容。你想恢復這個工作簿的內容嗎？如果您信任該工作簿的來源，如果我刪除行單擊Yes「
：
cell3.StyleIndex = 1;
我可以打開該文檔，但如果沒有格式化的日期，只顯示最新的數。
感謝您幫助格式化日期。
如果更改NumberFormatId和StyleIndex（CELL3）爲164的值，還是有一錯誤。 StyleIndex是否必須與NumberingFormatId具有相同的值？ – Dan 2011-05-17 17:05:49
@ daner06，no，StyleIndex引用單元樣式索引。 – 2011-05-18 00:24:58
某處是否有這些NumberFormatId值的列表？ – 2014-05-23 14:49:38
