我正在编写一个使用 OpenXML 创建 XLSX 文件的 C# 类。我已经设法实现了相当多的格式设置，但没有任何运气应用编号格式（特别是货币格式）。
我试图复制/调整我设法找到的其他人的代码示例，但是当您尝试打开电子表格时，所有这些都会导致可怕的“无效内容”错误。下面是我目前用来创建样式表的代码。我正在尝试添加 NumberingFormats （甚至还没有尝试在 CellFormat 中引用它但已经收到错误）：
/// <summary> A function to generate a style sheet which will allow the spreadsheet to use alternate fonts, fills, borders etc </summary>
private Stylesheet GenerateStyleSheet2()
{
// Create a new style sheet
Stylesheet newStyleSheet = new Stylesheet();
newStyleSheet.Append(new Fonts(
new Font( // Index 0 - The default font.
new FontSize() { Val = 11 },
new Color() { Rgb = new HexBinaryValue() { Value = "000000" } },
new FontName() { Val = "Calibri" }),
new Font( // Index 1 - The bold large font.
new Bold(),
new FontSize() { Val = 12 },
new Color() { Rgb = new HexBinaryValue() { Value = "000000" } },
new FontName() { Val = "Calibri" }),
new Font( // Index 2 - The bold and italic font.
new Bold(),
new Italic(),
new FontSize() { Val = 11 },
new Color() { Rgb = new HexBinaryValue() { Value = "000000" } },
new FontName() { Val = "Calibri" })
));
newStyleSheet.Append(new Fills(
new Fill( // Index 0 - The default fill.
new PatternFill() { PatternType = PatternValues.None }),
new Fill( // Index 1 - The default fill of gray 125 (required)
new PatternFill() { PatternType = PatternValues.LightGray }),
new Fill( // Index 2 - The orange fill.
new PatternFill(
new ForegroundColor() { Rgb = new HexBinaryValue() { Value = "FDD5B2" } }
) { PatternType = PatternValues.Solid }),
new Fill( // Index 3 - The row highlight custom colour.
new PatternFill(
new ForegroundColor() { Rgb = new HexBinaryValue() { Value = m_RowHighlightColour } }
) { PatternType = PatternValues.Solid })
));
newStyleSheet.Append(new Borders(
new Border( // Index 0 - The default border.
new LeftBorder(),
new RightBorder(),
new TopBorder(),
new BottomBorder(),
new DiagonalBorder()),
new Border( // Index 1 - Applies a Left, Right, Top, Bottom border to a cell
new LeftBorder(
new Color() { Auto = true }
) { Style = BorderStyleValues.Thin },
new RightBorder(
new Color() { Auto = true }
) { Style = BorderStyleValues.Thin },
new TopBorder(
new Color() { Auto = true }
) { Style = BorderStyleValues.Thin },
new BottomBorder(
new Color() { Auto = true }
) { Style = BorderStyleValues.Thin },
new DiagonalBorder())
));
// Add the numbering formats here
uint iExcelIndex = 0;
var numberingFormats = new NumberingFormats();
var nformat = new NumberingFormat
{
NumberFormatId = UInt32Value.FromUInt32(iExcelIndex),
FormatCode = StringValue.FromString("£#,##0.00")
};
numberingFormats.Append(nformat);
newStyleSheet.Append(numberingFormats);
newStyleSheet.Append( new CellFormats(
// Index 0 - The default style.
new CellFormat() { FontId = 0, FillId = 0, BorderId = 0, ApplyAlignment = true },
// Index 1 - The header style.
new CellFormat(new Alignment() { Horizontal = HorizontalAlignmentValues.Left, Vertical = VerticalAlignmentValues.Center }) { FontId = 1, FillId = 2, BorderId = 0, ApplyFont = true, ApplyFill = true },
// Index 2 - The boxed border style.
new CellFormat(new Alignment() { Horizontal = HorizontalAlignmentValues.Left, Vertical = VerticalAlignmentValues.Center }) { FontId = 0, FillId = 0, BorderId = 1, ApplyBorder = true },
// Index 3 - The default style (with left aligned).
new CellFormat(new Alignment() { Horizontal = HorizontalAlignmentValues.Left, Vertical = VerticalAlignmentValues.Center }) { FontId = 0, FillId = 0, BorderId = 0, ApplyAlignment = true },
// Index 4 - The footer style.
new CellFormat(new Alignment() { Horizontal = HorizontalAlignmentValues.Left, Vertical = VerticalAlignmentValues.Center }) { FontId = 2, FillId = 0, BorderId = 0, ApplyFont = true, ApplyAlignment = true },
// Index 5 - The custom highlight style.
new CellFormat(new Alignment() { Horizontal = HorizontalAlignmentValues.Left, Vertical = VerticalAlignmentValues.Center }) { FontId = 0, FillId = 3, BorderId = 0, ApplyAlignment = true, ApplyFill = true }
));
// Return the style sheet
return newStyleSheet;
}
已经坚持了几个小时了：（非常感谢任何帮助或指示！
