使用Open XML SDK 2.0将字符串数组作为行插入到Excel文档中

Question

代码运行，但破坏了我的Excel文档。任何帮助都会非常感激！我用this作为参考。

    public void AddRow(string fileName, string[] values) {
        using (SpreadsheetDocument doc =
            SpreadsheetDocument.Open(fileName, true)) {
            SharedStringTablePart sharedStringPart =
                GetSharedStringPart(doc);

            WorksheetPart worksheetPart =
                doc.WorkbookPart.WorksheetParts.First();
            uint rowIdx = AppendRow(worksheetPart);

            for (int i = 0; i < values.Length; ++i) {
                int stringIdx = InsertSharedString(values[i],
                    sharedStringPart);

                Cell cell = InsertCell(i, rowIdx, worksheetPart);
                cell.CellValue = new CellValue(stringIdx.ToString());
                cell.DataType = new EnumValue<CellValues>(
                    CellValues.SharedString);

                worksheetPart.Worksheet.Save();
            }
        }
    }

    private SharedStringTablePart GetSharedStringPart(
        SpreadsheetDocument doc) {
        if (doc.WorkbookPart.
            GetPartsCountOfType<SharedStringTablePart>() > 0)
            return doc.WorkbookPart.
                GetPartsOfType<SharedStringTablePart>().First();
        else
            return doc.WorkbookPart.
                AddNewPart<SharedStringTablePart>();
    }

    private uint AppendRow(WorksheetPart worksheetPart) {
        SheetData sheetData = worksheetPart.Worksheet.
            GetFirstChild<SheetData>();

        uint rowIndex = (uint)sheetData.Elements<Row>().Count();

        Row row = new Row() { RowIndex = rowIndex };
        sheetData.Append(row);

        return rowIndex;
    }

    private int InsertSharedString(string s,
        SharedStringTablePart sharedStringPart) {
        if (sharedStringPart.SharedStringTable == null)
            sharedStringPart.SharedStringTable =
                new SharedStringTable();

        int i = 0;

        foreach (SharedStringItem item in
            sharedStringPart.SharedStringTable.
            Elements<SharedStringItem>()) {
            if (item.InnerText == s)
                return i;
            ++i;
        }

        sharedStringPart.SharedStringTable.AppendChild(
            new Text(s));
        sharedStringPart.SharedStringTable.Save();

        return i;
    }

    private Cell InsertCell(int i, uint rowIdx,
        WorksheetPart worksheetPart) {
        SheetData sheetData = worksheetPart.Worksheet.
            GetFirstChild<SheetData>();
        string cellReference = AlphabetMap.Instance[i] + rowIdx;

        Cell cell = new Cell() { CellReference = cellReference };
        Row row = sheetData.Elements<Row>().ElementAt((int)rowIdx);

        row.InsertAt(cell, i);
        worksheetPart.Worksheet.Save();
        return cell;
    }

Answer 1

啊，找到了。在InsertSharedString方法中，

sharedStringPart.SharedStringTable.AppendChild(
        new Text(s));

应该

sharedStringPart.SharedStringTable.AppendChild(
        new SharedStringItem(new Text(s)));

Answer 2

我意识到这是一个非常古老的问题，但我发现/修复了原始代码的另一个问题：

string cellReference = AlphabetMap.Instance[i] + rowIdx;

应该：

string cellReference = AlphabetMap.Instance[i] + (rowIdx + 1);

这样，第一个CellReference是A1而不是A0，这会导致Excel在打开时崩溃
