Question

所以我需要将我的应用程序中的一些数据导出到xml文件中，并且我试图通过使用OpenXML来实现这一点，但我正在使用的代码生成aditional（封闭）元素并且它会阻止文件被打开。

<?xml version="1.0" encoding="utf-8"?>
<x:worksheet xmlns:x="http://schemas.openxmlformats.org/spreadsheetml/2006/main">
<x:sheetData /> <---- this guy here.
<x:sheetData>
<x:row><x:c t="str">
<x:v>Key</x:v></x:c>
<x:c t="str"><x:v>Value</x:v></x:c>
</x:row>
</x:sheetData>
</x:worksheet>

这是我用来生成文件的代码。

    SpreadsheetDocument spreadsheetDocument = SpreadsheetDocument.Create(System.IO.Path.Combine(currentPath, "Export Data") + $@"\Export-{DateTime.Now.Year}.xlsx", SpreadsheetDocumentType.Workbook);

    WorkbookPart workbookpart = spreadsheetDocument.AddWorkbookPart();
    workbookpart.Workbook = new Workbook();

    WorksheetPart worksheetPart = workbookpart.AddNewPart<WorksheetPart>();
    worksheetPart.Worksheet = new Worksheet(new SheetData());

    Sheets sheets = spreadsheetDocument.WorkbookPart.Workbook.AppendChild<Sheets>(new Sheets());
    Sheet sheet = new Sheet()
    {
        Id = spreadsheetDocument.WorkbookPart.
            GetIdOfPart(worksheetPart),
            SheetId = 1,
            Name = "Temp"
    };
    sheets.Append(sheet);
    SheetData sheetData = worksheetPart.Worksheet.AppendChild(new SheetData());
    Row row = new Row();
    row.Append(
        ConstructCell("Key", CellValues.String),
        ConstructCell("Value", CellValues.String));
    sheetData.AppendChild(row);
    worksheetPart.Worksheet.Save();
    spreadsheetDocument.Close();

有谁能告诉我额外的“SheetData”元素来自哪里？我不能仅仅通过观察来判断。

Answer 1

我太蠢了。在我发布问题之后，我发现我正在创建一个不必要的sheetdata元素

WorksheetPart worksheetPart = workbookpart.AddNewPart<WorksheetPart>();
worksheetPart.Worksheet = new Worksheet(new SheetData()); // HERE

OpenXML生成一个空的SheetData元素
