修复记录：来自/xl/styles.xml部分的格式（样式）

为什么要修理我不明白？

m_objSpreadsheetDocument = SpreadsheetDocument.Create(FileName, SpreadsheetDocumentType.Workbook);
m_objWorkbookPart = m_objSpreadsheetDocument.AddWorkbookPart();
m_objWorkbookPart.Workbook = new Workbook();

// Add a WorksheetPart to the WorkbookPart.
m_objWorksheetPart = m_objWorkbookPart.AddNewPart<WorksheetPart>();
m_objWorksheetPart.Worksheet = new Worksheet(new SheetData());
m_objWorksheet = m_objWorksheetPart.Worksheet;

// Add Sheets to the Workbook.
Sheets sheets = m_objSpreadsheetDocument.WorkbookPart.Workbook.AppendChild<Sheets>(new Sheets());

// Append a new worksheet and associate it with the workbook.
Sheet sheet = new Sheet()
{
    Id = m_objSpreadsheetDocument.WorkbookPart.GetIdOfPart(m_objWorksheetPart),
    SheetId = 1,
    Name = _sheetName
};
sheets.Append(sheet);

wStylePart = m_objSpreadsheetDocument.WorkbookPart.AddNewPart<WorkbookStylesPart>();

m_objSheetData = m_objWorksheetPart.Worksheet.GetFirstChild<SheetData>();

Answer 1

没有设置WorkbookStylesPart你不能有Stylesheet。您需要删除该行

wStylePart = m_objSpreadsheetDocument.WorkbookPart.AddNewPart<WorkbookStylesPart>();

或者你可以设置它的StyleSheet属性：

var wStylePart = m_objSpreadsheetDocument.WorkbookPart.AddNewPart<WorkbookStylesPart>();
wStylePart.Stylesheet = new Stylesheet();

编辑

你还需要在Close上调用SpreadsheetDocument。您可以在代码底部添加对m_objSpreadsheetDocument.Close();的调用，或者最好在SpreadsheetDocument.Create语句中将调用包装到using。

完整的代码将如下所示：

using (var m_objSpreadsheetDocument = SpreadsheetDocument.Create(file, SpreadsheetDocumentType.Workbook))
{
    var m_objWorkbookPart = m_objSpreadsheetDocument.AddWorkbookPart();
    m_objWorkbookPart.Workbook = new Workbook();

    // Add a WorksheetPart to the WorkbookPart.
    var m_objWorksheetPart = m_objWorkbookPart.AddNewPart<WorksheetPart>();
    m_objWorksheetPart.Worksheet = new Worksheet(new SheetData());
    var m_objWorksheet = m_objWorksheetPart.Worksheet;

    // Add Sheets to the Workbook.
    Sheets sheets = m_objSpreadsheetDocument.WorkbookPart.Workbook.AppendChild<Sheets>(new Sheets());

    // Append a new worksheet and associate it with the workbook.
    Sheet sheet = new Sheet()
    {
        Id = m_objSpreadsheetDocument.WorkbookPart.GetIdOfPart(m_objWorksheetPart),
        SheetId = 1,
        Name = "Sheet 1"
    };
    sheets.Append(sheet);

    //either both of these lines are required or neither of them; you can't add the WorkbookStylesPart alone
    var wStylePart = m_objSpreadsheetDocument.WorkbookPart.AddNewPart<WorkbookStylesPart>();
    wStylePart.Stylesheet = new Stylesheet();

    var m_objSheetData = m_objWorksheetPart.Worksheet.GetFirstChild<SheetData>();
}
