我在OpenXml / C＃代码中遇到Cell Style问题。
我无法为单元格定义样式。我尝试了很多方法来做到这一点，但我没有成功。有人能帮助我吗？
应用Cell Style的这部分代码是：
Stylesheet stylesheet = spreadsheet.WorkbookPart.WorkbookStylesPart.Stylesheet;
WorkbookPart workbookPart = spreadsheet.WorkbookPart;
Fonts fonts = stylesheet.Fonts;//new Fonts() { Count = (UInt32Value)1U };
Font font = new Font();
FontSize newFontSize = new FontSize() { Val = fontSize };
Color newFontColor = new Color() { Rgb = new HexBinaryValue(fontColor) };
FontName newFontName = new FontName() { Val = fontName };
FontScheme fontScheme = new FontScheme() { Val = FontSchemeValues.Minor };
font.Append(newFontSize);
font.Append(newFontColor);
font.Append(newFontName);
font.Append(fontScheme);
if (bold == true)
{
Bold newBold = new Bold();
font.Append(newBold);
}
if (italic == true)
{
Italic newItalic = new Italic();
font.Append(newItalic);
}
if (underline == true)
{
Underline newUnderline = new Underline();
font.Append(newUnderline);
}
fonts.Append(font);
Fills fills = stylesheet.Fills;//new Fills() { Count = (UInt32Value)1U };
Fill fill = new Fill(new PatternFill()
{
PatternType = PatternValues.Solid,
ForegroundColor = new ForegroundColor() { Rgb = new HexBinaryValue(foregroundColor) }
});
fills.Append(fill);
Borders borders = stylesheet.Borders; //new Borders() { Count = (UInt32Value)1U };
Border border = new Border();
if (borderDefault == true)
{
BottomBorder bottomBorder = new BottomBorder(new Color() { Auto = true }) { Style = BorderStyleValues.Thin };
TopBorder topBorder = new TopBorder(new Color() { Auto = true }) { Style = BorderStyleValues.Thin };
LeftBorder leftBorder = new LeftBorder(new Color() { Auto = true }) { Style = BorderStyleValues.Thin };
RightBorder rightBorder = new RightBorder(new Color() { Auto = true }) { Style = BorderStyleValues.Thin };
border.Append(leftBorder);
border.Append(rightBorder);
border.Append(topBorder);
border.Append(bottomBorder);
borders.Append(border);
}
CellStyleFormats cellStyleFormats = stylesheet.CellStyleFormats;
UInt32 fontIndex = fonts.Count;
UInt32 fillIndex = fills.Count;
UInt32 borderIndex = borders.Count;
CellFormat cellFormat = new CellFormat() { NumberFormatId = (UInt32Value)0U, FontId = fontIndex, FillId = fillIndex, BorderId = borderIndex, FormatId = (UInt32Value)0U, ApplyFont = true, ApplyFill = true, ApplyBorder = true, ApplyAlignment = alignment };
if (alignment == false)
{
Alignment alignment1 = new Alignment() { Horizontal = HorizontalAlignmentValues.Left, Vertical = VerticalAlignmentValues.Center };
}
else
{
Alignment alignment1 = new Alignment() { Horizontal = HorizontalAlignmentValues.Center, Vertical = VerticalAlignmentValues.Center };
}
cellStyleFormats.Append(cellFormat);
UInt32 formatIndex = cellStyleFormats.Count;
CellStyles cellStyles = stylesheet.CellStyles;//new CellStyles() { Count = (UInt32Value)0U };
CellStyle cellStyle = new CellStyle() { Name = "Normal", FormatId = formatIndex, BuiltinId = (UInt32Value)0U };
cellStyles.Append(cellStyle);
//stylesheet.Append(cellStyleFormats);
//stylesheet.Append(fills);
//stylesheet.Append(borders);
//stylesheet.Append(cellFormat);
//stylesheet.Append(cellStyles);
stylesheet.Save();
cell.StyleIndex = formatIndex;
spreadsheet.WorkbookPart.WorkbookStylesPart.Stylesheet.Save();

我们是如何做到的;也许这种方法会对你有所帮助。我们创建了一个外部样式表并将其保存到电子表格
创建Excel文件：
using (SpreadsheetDocument spreadsheetDocument = SpreadsheetDocument.Create(fileStream, SpreadsheetDocumentType.Workbook))
{
// Add a WorkbookPart to the document.
WorkbookPart workbookpart = spreadsheetDocument.AddWorkbookPart();
workbookpart.Workbook = new Workbook();
WorkbookStylesPart stylesPart = spreadsheetDocument.WorkbookPart.AddNewPart<WorkbookStylesPart>();
stylesPart.Stylesheet = new Stylesheet();
stylesPart.Stylesheet.InnerXml = this.GenerateStyleSheet();
stylesPart.Stylesheet.Save();
WorksheetPart worksheetPart = workbookpart.AddNewPart<WorksheetPart>();
worksheetPart.Worksheet = new Worksheet(new SheetData());
// Add Sheets to the Workbook.
Sheets sheets = spreadsheetDocument.WorkbookPart.Workbook.AppendChild<Sheets>(new Sheets());
// Append a new worksheet and associate it with the workbook.
Sheet sheet = new Sheet() { Id = spreadsheetDocument.WorkbookPart.GetIdOfPart(worksheetPart), SheetId = 1, Name = "Result" };
sheets.Append(sheet);
workbookpart.Workbook.Save();
// Close the document.
spreadsheetDocument.Close();
}
获取样式表的方法：
public string GenerateStyleSheet()
{
if (this.StylesheetFormat == null)
{
using (var styleXmlReader = new System.IO.StreamReader(AppDomain.CurrentDomain.BaseDirectory + @"\bin\Resources\ExcelStyleSheet.xml"))
{
this.StylesheetFormat = styleXmlReader.ReadToEnd();
}
}
return this.StylesheetFormat;
}
样式表xml：
