我正在使用 C# 以 XML 格式编写 OpenDocument 电子表格。编写双精度值没问题，就像这样可以正常工作：

    private void SaveFloatCell(XmlNode rowNode, XmlDocument ownerDocument, double number)
    {
        XmlElement cellNode = ownerDocument.CreateElement("table:table-cell", this.GetNamespaceUri("table"));

        XmlAttribute valueType = ownerDocument.CreateAttribute("office:value-type", this.GetNamespaceUri("office"));
        valueType.Value = "float";
        cellNode.Attributes.Append(valueType);

        XmlAttribute value = ownerDocument.CreateAttribute("office:value", this.GetNamespaceUri("office"));
        value.Value = number.ToString(CultureInfo.InvariantCulture);
        cellNode.Attributes.Append(value);

        rowNode.AppendChild(cellNode);
    }

但是，当尝试保存 DateTime 值时，我无法正确显示它们。这是我到目前为止所拥有的，它在单元格中显示“2012”而不是指定的日期格式：

    private void SaveDateTimeCell(XmlNode rowNode, XmlDocument ownerDocument, double number, string format)
    {
        XmlElement cellNode = ownerDocument.CreateElement("table:table-cell", this.GetNamespaceUri("table"));

        XmlAttribute valueType = ownerDocument.CreateAttribute("office:value-type", this.GetNamespaceUri("office"));
        valueType.Value = "date";
        cellNode.Attributes.Append(valueType);

        XmlAttribute value = ownerDocument.CreateAttribute("office:value", this.GetNamespaceUri("office"));
        value.Value = Utils.DateTime(number).ToString("yyyy-mm-ddThh:mm:ss");
        cellNode.Attributes.Append(value);

        rowNode.AppendChild(cellNode);
    }

我花了很长时间玩我发现的各种代码片段，但没有成功。顺便说一句，有没有任何慷慨的灵魂可以帮助我解决这个问题？

非常感谢！

鉴于当前已损坏，您可能只需要修复格式：

value.Value = Utils.DateTime(number).ToString("yyyy-MM-ddTHH:mm:ss");

变化：

  • 使用 M 表示月份，而不是 m（表示分钟）
  • 使用 HH 表示小时，而不是 hh（即 12 小时制）

我建议您也指定inh CultureInfo.InvariantCulture，以表明您不希望应用任何文化设置。

好的，我有答案了。最终代码如下所示：

    private void SaveDateTimeCell(XmlNode rowNode, XmlDocument ownerDocument, double number, string format)
    {
        XmlElement cellNode = ownerDocument.CreateElement("table:table-cell", this.GetNamespaceUri("table"));

        XmlAttribute valueType = ownerDocument.CreateAttribute("office:value-type", this.GetNamespaceUri("office"));
        valueType.Value = "date";
        cellNode.Attributes.Append(valueType);

        XmlAttribute value = ownerDocument.CreateAttribute("office:date-value", this.GetNamespaceUri("office"));
        value.Value = Utils.DateTime(number).ToString("yyyy-MM-ddTHH:mm:ss");
        cellNode.Attributes.Append(value);

        XmlAttribute tableStyleName = ownerDocument.CreateAttribute("table:style-name", this.GetNamespaceUri("table"));
        tableStyleName.Value = "ce2";
        cellNode.Attributes.Append(tableStyleName);

        rowNode.AppendChild(cellNode);
    }

关键是“ce2”的定义。这是在解压后的 *.ods 文件的 styles.xml 文件中完成的：

    private void SaveStyleSheet(XmlNode sheetsRootNode)
    {
        XmlDocument ownerDocument = sheetsRootNode.OwnerDocument;

        XmlNode sheetNode = ownerDocument.CreateElement("number:date-style", this.GetNamespaceUri("number"));

        XmlAttribute styleName = ownerDocument.CreateAttribute("style:name", this.GetNamespaceUri("style"));
        styleName.Value = "N19";
        sheetNode.Attributes.Append(styleName);

        XmlElement numberDay = ownerDocument.CreateElement("number:day", this.GetNamespaceUri("number"));
        XmlAttribute numberStyle = ownerDocument.CreateAttribute("number:style", this.GetNamespaceUri("number"));
        numberStyle.Value = "long";
        numberDay.Attributes.Append(numberStyle);
        sheetNode.AppendChild(numberDay);

        XmlElement numberText = ownerDocument.CreateElement("number:text", this.GetNamespaceUri("number"));
        numberText.InnerText = "/";
        sheetNode.AppendChild(numberText);

        XmlElement numberMonth = ownerDocument.CreateElement("number:month", this.GetNamespaceUri("number"));
        XmlAttribute numberStyle2 = ownerDocument.CreateAttribute("number:style", this.GetNamespaceUri("number"));
        numberStyle2.Value = "long";
        numberMonth.Attributes.Append(numberStyle2);
        sheetNode.AppendChild(numberMonth);

        XmlElement numberText2 = ownerDocument.CreateElement("number:text", this.GetNamespaceUri("number"));
        numberText2.InnerText = "/";
        sheetNode.AppendChild(numberText2);

        XmlElement numberYear = ownerDocument.CreateElement("number:year", this.GetNamespaceUri("number"));
        XmlAttribute numberStyle3 = ownerDocument.CreateAttribute("number:style", this.GetNamespaceUri("number"));
        numberStyle3.Value = "long";
        numberYear.Attributes.Append(numberStyle3);
        sheetNode.AppendChild(numberYear);

        sheetsRootNode.AppendChild(sheetNode);
    }

然后在解压缩的 *.ods 文件的 content.xml 的自动样式中引用此日期样式 N19，因此：

    private void SaveAutomaticStyleSheet(XmlNode sheetsRootNode)
    {
        XmlDocument ownerDocument = sheetsRootNode.OwnerDocument;

        XmlNode sheetNode = ownerDocument.CreateElement("style:style", this.GetNamespaceUri("style"));

        XmlAttribute styleName = ownerDocument.CreateAttribute("style:name", this.GetNamespaceUri("style"));
        styleName.Value = "ce2";
        sheetNode.Attributes.Append(styleName);

        XmlAttribute styleFamily = ownerDocument.CreateAttribute("style:family", this.GetNamespaceUri("style"));
        styleFamily.Value = "table-cell";
        sheetNode.Attributes.Append(styleFamily);

        XmlAttribute styleParentStyleName = ownerDocument.CreateAttribute("style:parent-style-name", this.GetNamespaceUri("style"));
        styleParentStyleName.Value = "Default";
        sheetNode.Attributes.Append(styleParentStyleName);

        XmlAttribute styleDataStyleName = ownerDocument.CreateAttribute("style:data-style-name", this.GetNamespaceUri("style"));
        styleDataStyleName.Value = "N19";
        sheetNode.Attributes.Append(styleDataStyleName);

        sheetsRootNode.AppendChild(sheetNode);
    }

事实上，Jon 的建议对于代码完美运行也是必要的。所以再次感谢乔恩。无论如何，确实是一种黑色，黑色的艺术...... :)
