OpenXML Spreadsheet：Excel提供了一个错误，然后修复它，它工作。 （C＃）

我缩小到：

//aantal auto's Row aantalAutosRow = new Row(); aantalAutosRow.RowIndex = Convert.ToUInt32((tblXML.Rows.Count) + 2); Cell aantalAutosCell = new Cell(); aantalAutosCell.CellReference = getColumnName(1); aantalAutosCell.CellValue = new CellValue("Hoi"); aantalAutosRow.Append(aantalAutosCell); sheetData.Append(aantalAutosRow); 

当Excel提示修复文件（sheet.xml）时，单击“是”后，将生成“单元格”

完整的课程：

有人可以告诉我，我在做什么，这是违法的Excel？ 我认为excel使得修复SharedStrings成为可能。 我从来没有与SharedStrings工作，我希望我不必。

Answer 1

我浏览了你的代码，发现了4个需要改变的地方，以便生成一个无错的excel文档。

1.replacestylesPart.Stylesheet = s.GenerateStyleSheet(); stylesPart.Stylesheet = new Stylesheet();

2.注释如下： //headerCell.StyleIndex = 1;

3.注释如下： //StyleIndex = 6,

4.添加了以下内容： aantalAutosCell.DataType = CellValues.String;

下面的代码适用于我，并生成一个无错误的Excel文档。 几个你需要知道的指针

1.在使用Open XML Docs时，不能任意指定样式索引

2.当你有一个string数据types被存储时，你应该使用CellValues.String（因为你不想使用共享string）

3.使用Open XML SDK时阅读SharedStrings是非常值得的。 共享string减less文件的整体大小，让事情变得更好。 请参阅http://msdn.microsoft.com/en-us/library/office/gg278314.aspx
