C# 如何在打开的XML工作表中插入日期?
我使用的是MicrosoftOpenXMLSDK2,我很难在单元格中插入日期。通过设置C# 如何在打开的XML工作表中插入日期?,c#,excel,openxml,openxml-sdk,C#,Excel,Openxml,Openxml Sdk,我使用的是MicrosoftOpenXMLSDK2,我很难在单元格中插入日期。通过设置Cell.DataType=CellValues.Number,我可以毫无问题地插入数字,但当我对日期(Cell.DataType=CellValues.date)执行相同操作时,Excel 2010也会崩溃(2007) 我尝试将Cell.Text值设置为多种日期格式以及Excel的日期/数字格式,但均无效。我还尝试使用样式,删除了type属性,以及我扔在墙上的许多其他比萨饼 有人能给我举一个向工作表中插入日期

值设置为多种日期格式以及Excel的日期/数字格式,但均无效。我还尝试使用样式,删除了type属性,以及我扔在墙上的许多其他比萨饼
有人能给我举一个向工作表中插入日期的例子吗?您必须使用函数
toadate将DateTime
转换为double
,即:
DateTime dtValue = DateTime.Now;
string strValue = dtValue.ToOADate().ToString(CultureInfo.InvariantCulture);
然后将其设置为CellValue
Cell cell;
cell.DataType = new EnumValue<CellValues>(CellValues.Date);
cell.CellValue = new CellValue(strValue);
细胞;
cell.DataType=新的枚举值(CellValues.Date);
cell.CellValue=新的CellValue(strValue);
请记住使用DateTime
格式设置单元格格式,否则您将看到double
值,而不是日期。使用共享字符串:
// assuming it's the first item in the shared string table
SharedStringItem sharedStringItem = new SharedStringItem();
Text text = new Text();
text.Text = DateTime.Today.ToString("MM/dd/yyyy hh:mm");
sharedStringTable1.Append(sharedStringItem);
然后在后面的代码中:
// assuming it's the first item in the shared string table
var cell = new Cell {CellReference = "A1", DataType = CellValues.SharedString};
var cellValue = new CellValue("0");
cell.Append(cellValue);
以下几点对我们起了作用:
c.CellValue = new CellValue(datetimeValue).ToOADate().ToString());
c.DataType = CellValues.Number;
c.StyleIndex = StyleDate;
将数据类型设置为CellValues.Number,然后确保使用CellFormats中的适当样式索引格式化单元格。在我们的例子中,我们在工作表中构建了一个样式表,StyleDate是样式表中单元格格式的索引。我使用了Andrew J提供的代码,但是数据类型
为我生成了一个损坏的xlsx文件
DataType
CellValues.Number对我来说很好(别忘了设置NumberFormatId
):
如果您想以另一种方式设置日期格式,下面是所有默认Excel格式的列表

我知道这个列表来自ClosedXML,但在OpenXML中它是相同的。当从头开始创建新的电子表格文档时,要使日期
格式有效,必须创建最小的样式表
关键是以下几行:
new CellFormat
{
NumberFormatId = 14,
ApplyNumberFormat = true
})
完整的样式表
类:
using (var spreadSheet = SpreadsheetDocument.Create(ms, SpreadsheetDocumentType.Workbook))
{
// Workbook
var workbookPart = spreadSheet.AddWorkbookPart();
workbookPart.Workbook =
new Workbook(new Sheets(new Sheet { Name = "Sheet1", SheetId = (UInt32Value) 1U, Id = "rId1" }));
// Add minimal Stylesheet
var stylesPart = spreadSheet.WorkbookPart.AddNewPart<WorkbookStylesPart>();
stylesPart.Stylesheet = new Stylesheet
{
Fonts = new Fonts(new Font()),
Fills = new Fills(new Fill()),
Borders = new Borders(new Border()),
CellStyleFormats = new CellStyleFormats(new CellFormat()),
CellFormats =
new CellFormats(
new CellFormat(),
new CellFormat
{
NumberFormatId = 14,
ApplyNumberFormat = true
})
};
// Continue creating `WorksheetPart`...
请注意,StyleIndex
值取决于CellFormats
数组或Stylesheet
对象中CellFormat
项的顺序。在本例中,数组中第二项的NumberFormatId=14
项。有两种方法在OpenXml中存储日期;通过写入一个数字(使用ToOADate
)并将数据类型设置为number
,或者通过写入格式化日期并将数据类型设置为日期
。请注意,默认的数据类型
是数字
,因此如果使用第一个选项,则不必设置数据类型
无论选择哪种方法,都需要将样式设置为Excel以相同方式显示这两种方法。以下代码显示了使用数字
格式(有无明确设置数据类型
)和ISO 8601格式写入日期的示例
using (SpreadsheetDocument document = SpreadsheetDocument.Create(filename, SpreadsheetDocumentType.Workbook))
{
//fluff to generate the workbook etc
WorkbookPart workbookPart = document.AddWorkbookPart();
workbookPart.Workbook = new Workbook();
