NPOI / POI Excel Lib ISheet.ShiftRows 索引超出范围异常

Question

我在 NPOI 中使用 .ShiftRows 将新行插入 Excel 文件。但是，在尝试将行向下移动以插入新行时，我在某些文件上得到了 System.ArgumentOutOfRangeException。这些只是我正在填充的不同公司的通用文件，因此它们可能不是“干净的”，即底部的空白行等。我希望它仍然运行，因为 NPOI 知道最后一行在哪里。

在这种情况下，我将第 16 行到第 458 行向下移动并得到了超出范围的异常。

例外：

Server Error in '/' Application.

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

我已将一些 POI 代码从 here 修改为 NPOI 以使其正常工作。

CopyRow 函数：

private static void CopyRow(IWorkbook iWorkbook, ISheet iSheet, int sourceRowNum, int destinationRowNum)
{
    // Get the source / new row
    IRow newRow = iSheet.GetRow(destinationRowNum);
    IRow sourceRow = iSheet.GetRow(sourceRowNum);

    // If the row exist in destination, push down all rows by 1 else create a new row
    if (newRow != null)
    {
        iSheet.ShiftRows(destinationRowNum, iSheet.LastRowNum, 1); // this is causing the issue
    }
    else
    {
        newRow = iSheet.CreateRow(destinationRowNum);
    }

    // Loop through source columns to add to new row
    for (int i = 0; i < sourceRow.LastCellNum; i++)
    {
        // Grab a copy of the old/new cell
        ICell oldCell = sourceRow.GetCell(i);
        ICell newCell = newRow.CreateCell(i);

        // If the old cell is null jump to next cell
        if (oldCell == null)
        {
            newCell = null;
            continue;
        }

        // Copy style from old cell and apply to new cell
        ICellStyle newCellStyle = iWorkbook.CreateCellStyle();
        newCellStyle.CloneStyleFrom(oldCell.CellStyle);
        ;
        newCell.CellStyle = newCellStyle;

        // If there is a cell comment, copy
        if (oldCell.CellComment != null)
        {
            newCell.CellComment = oldCell.CellComment;
        }

        // If there is a cell hyperlink, copy
        if (oldCell.Hyperlink != null)
        {
            newCell.Hyperlink = oldCell.Hyperlink;
        }

        // Set the cell data type
        newCell.SetCellType(oldCell.CellType);

        // Set the cell data value
        switch (oldCell.CellType)
        {
            case CellType.Blank:
                newCell.SetCellValue(oldCell.StringCellValue);
                break;
            case CellType.Boolean:
                newCell.SetCellValue(oldCell.BooleanCellValue);
                break;
            case CellType.Error:
                newCell.SetCellErrorValue(oldCell.ErrorCellValue);
                break;
            case CellType.Formula:
                newCell.SetCellFormula(oldCell.CellFormula);
                break;
            case CellType.Numeric:
                newCell.SetCellValue(oldCell.NumericCellValue);
                break;
            case CellType.String:
                newCell.SetCellValue(oldCell.RichStringCellValue);
                break;
        }
    }

    // If there are are any merged regions in the source row, copy to new row
    for (int i = 0; i < iSheet.NumMergedRegions; i++)
    {
        CellRangeAddress cellRangeAddress = iSheet.GetMergedRegion(i);
        if (cellRangeAddress.FirstRow == sourceRow.RowNum)
        {
            CellRangeAddress newCellRangeAddress = new CellRangeAddress(newRow.RowNum,
                      (newRow.RowNum +
                                 (cellRangeAddress.LastRow - cellRangeAddress.FirstRow
                                            )),
                      cellRangeAddress.FirstColumn,
                      cellRangeAddress.LastColumn);
            iSheet.AddMergedRegion(newCellRangeAddress);
        }
    }
}

之前有人遇到过 NPOI 或 POI 的这个问题吗？

使用 NPOI v2.2.1。

编辑：我将相同的文件保存为 .xls（以前是 .xlsx）并且没有问题。可能与仅用于 XSSFWorkbook 的 .ShiftRows 有关...将继续为您提供最新信息。

Answer 1

此问题已在 NPOI V2.3.0 中修复。

我试过了。
