无法使用openxml在Excel中设置所需的背景颜色

我是新来打开XML并试图设置标题行的背景颜色为灰色，但它总是将其设置为黑色。 请参考我正在使用的以下代码。

return new Stylesheet( new Fonts( new Font( // Index 0 - The default font. new DocumentFormat.OpenXml.Spreadsheet.FontSize() { Val = 11 }, new Color() { Rgb = new HexBinaryValue() { Value = "000000" } }, new FontName() { Val = "Calibri" }), new Font( // Index 1 - The bold white font. new DocumentFormat.OpenXml.Spreadsheet.Bold(), new DocumentFormat.OpenXml.Spreadsheet.FontSize() { Val = 11 }, new DocumentFormat.OpenXml.Spreadsheet.Color() { Rgb = new HexBinaryValue() { Value = "ffffff" } }, new DocumentFormat.OpenXml.Spreadsheet.FontName() { Val = "Calibri" }), new Font( // Index 2 - The bold red font. new DocumentFormat.OpenXml.Spreadsheet.Bold(), new DocumentFormat.OpenXml.Spreadsheet.FontSize() { Val = 11 }, new DocumentFormat.OpenXml.Spreadsheet.Color() { Rgb = new HexBinaryValue() { Value = "ff0000" } }, new DocumentFormat.OpenXml.Spreadsheet.FontName() { Val = "Calibri" }), new Font( // Index 2 - The bold red font. new DocumentFormat.OpenXml.Spreadsheet.Bold(), new DocumentFormat.OpenXml.Spreadsheet.FontSize() { Val = 11 }, new DocumentFormat.OpenXml.Spreadsheet.Color() { Rgb = new HexBinaryValue() { Value = "000000" } }, new DocumentFormat.OpenXml.Spreadsheet.FontName() { Val = "Calibri" }) ), 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.Gray125 }), new Fill( // Index 2 - The blue fill. new PatternFill( new ForegroundColor() { Rgb = new HexBinaryValue() { Value = "006699" } } ) { PatternType = PatternValues.Solid }), new Fill( // Index 3 - The grey fill. new PatternFill( new BackgroundColor () { Rgb = new HexBinaryValue(){ Value = "808080" } } ) { PatternType = PatternValues.Solid } ) ), 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()) ), new CellFormats( new CellFormat(new Alignment() { Horizontal = HorizontalAlignmentValues.Center, Vertical = VerticalAlignmentValues.Center }) { FontId = 1, FillId = 0, BorderId = 0 }, // Index 0 - The default cell style. If a cell does not have a style index applied it will use this style combination instead new CellFormat( new Alignment() { Horizontal = HorizontalAlignmentValues.Center, Vertical = VerticalAlignmentValues.Center } ) { FontId = 1, FillId = 2, BorderId = 0, ApplyFont = true }, // Index 1 - Bold White Blue Fill new CellFormat(new Alignment() { Horizontal = HorizontalAlignmentValues.Center, Vertical = VerticalAlignmentValues.Center } ) { FontId = 2, FillId = 2, BorderId = 0, ApplyFont = true } , // Index 2 - Bold Red Blue Fill new CellFormat(new Alignment() { Horizontal = HorizontalAlignmentValues.Center, Vertical = VerticalAlignmentValues.Center } ) { FontId = 3, FillId = 3, BorderId = 0, ApplyFont = true } ) ); // return

PatternFill的文档（ ECMA-376标准的 PatternFill节）说（强调我的）：

对于固体细胞填充（无图案），使用fgColor 。 对于指定了模式的单元格填充，单元格填充颜色由bgColor元素指定。

你已经指定了PatternType = PatternValues.Solid但是你提供了一个BackgroundColor而不是ForegroundColor 。 从BackgroundColor更改为ForegroundColor将解决您的问题，即这条线：

 new BackgroundColor() { Rgb = new HexBinaryValue(){ Value = "808080" } } 

应该成为：

 new ForegroundColor() { Rgb = new HexBinaryValue() { Value = "808080" } }
