使用OpemXML和C＃插入现有Excel文件会导致Excel出现内容问题并强制进行修复

Question

我可以运行以下代码而不会出现错误或异常（代码方面）

private ExcelRow CreateContentRow(int index, StockHolder stockholder)
{
    ExcelRow r = new ExcelRow();
    r.RowIndex = (UInt32)index + 1;
    int i = 0;

    string[] headerColumns = new string[] { "A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K" };
    var eraseThis = stockholder.GetType().GetProperties().Count();
    foreach (var prop in stockholder.GetType().GetProperties())
    {
        ExcelCell c = new ExcelCell();
        c.CellReference = headerColumns[i].ToString() + index;

        if (prop.PropertyType.ToString().Equals("System.string", StringComparison.InvariantCultureIgnoreCase))
        {
            var result = prop.GetValue(stockholder, null);

            if (result == null)
            {
                result = "";
            }

            c.DataType = CellValues.String;
            InlineString inlineString = new InlineString();
            Text t = new Text();
            t.Text = result.ToString();
            inlineString.AppendChild(t);
            c.AppendChild(inlineString);
        }

    //Other "if" statements here for checking bool and numeric (similar to the above "if" statement, but none of them are used at this time

    return r;
}

＆＃34;索引＆＃34;参数是我试图添加到的工作表中的行数（它似乎能够读取工作表名称（因为只有一个）但是＆＃34; Stockholder＆＃34; parameter是带有填充数据的自定义对象（都不是null）

问题是我之后尝试打开Excel文档

当我单击是时，它会显示此弹出窗口

当我尝试搜索时，

结果对于另一个第三方库（以＆＃34; ERPPS＆＃34;或类似的东西开头）更有用。在调试时，属性似乎正确映射（使用另一种方法进行映射，并且它们仍然是所有字符串）。任何帮助或链接将不胜感激，因为我已经有一段时间了解这一点。并且，目前使用网络应用程序或表单不是替代方案（很久以前会感到羞耻）。感谢

编辑 - 此外，这里是调用方法（因为它也可能是它的一部分）

private void InsertIntoExistingExcel(StockHolder sh)
{
    using (SpreadsheetDocument myWorkbook = SpreadsheetDocument.Open(locationOfExcelFile, true))
    {
        WorkbookPart workbookPart = myWorkbook.WorkbookPart;
        var stockHolderInfo_Sheet = myWorkbook.WorkbookPart.Workbook.Sheets.GetFirstChild<Sheet>();
        IEnumerable<Sheet> Sheets = new List<Sheet>() { stockHolderInfo_Sheet };
        if (Sheets.Count() > 0)
        {
            string relationshipId = Sheets.First().Id.Value;
            WorksheetPart worksheetPart = (WorksheetPart)myWorkbook.WorkbookPart.GetPartById(relationshipId);
            SheetData sheetdata = worksheetPart.Worksheet.GetFirstChild<SheetData>();
            var sheetDataCount = sheetdata.Count();
            var newContentRow = CreateContentRow(sheetDataCount, sh);
            sheetdata.AppendChild(newContentRow);
            workbookPart.Workbook.Save();
        }
    }
}

解决了！或者更确切地说，使用不同的方法

    private void interopExcelInsertion(StockHolder sh, int rowNumberToUpdate)
    {
        ExcelInterop.Application oApp;
        ExcelInterop.Worksheet oSheet;
        ExcelInterop.Workbook oBook;

        oApp = new ExcelInterop.Application();
        oBook = oApp.Workbooks.Open(locationAndNameOfExcelFile);
        oSheet = oBook.Worksheets[1] as Microsoft.Office.Interop.Excel.Worksheet;

        var rowToUpdate = rowNumberToUpdate > 0 ? rowNumberToUpdate : oSheet.Cells.SpecialCells(ExcelInterop.XlCellType.xlCellTypeLastCell, System.Type.Missing).Row;
        int i = 1;
        foreach (var prop in sh.GetType().GetProperties())
        {
            var result = prop.GetValue(sh, null);
            oSheet.Cells[rowToUpdate + 1, i] = result == null ? "" : result.ToString();
            i++;
        }

        oBook.Save();
        oBook.Close();
        oApp.Quit();
        //Marshal.ReleaseComObject(oApp);
    }
