NPOI / POI Excel库ISheet.ShiftRows索引超出范围例外
我正在使用NPOI中的.ShiftRows插入一个新的行到一个Excel文件。 但是，当试图向下移动行以插入新行时，我在某些文件上收到System.ArgumentOutOfRangeException 。 这些只是我填充的不同公司的通用文件，因此它们可能不是“干净的”，即底部的空白行等等。我希望它仍然可以运行，因为NPOI知道最后一行在哪里。
在这种情况下，我将行16到458向下移动，得到了超出范围的exception。
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. Exception Details: System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index Source Error: Line 564: if (newRow != null) Line 565: { Line 566: iSheet.ShiftRows(destinationRowNum, iSheet.LastRowNum, 1); Line 567: } Line 568: else

我已经从这里修改了一些POI代码到NPOI来完成这项工作。
CopyRowfunction：
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); } } }
有没有人遇到过NPOI或POI这个问题？
使用NPOI v2.2.1。
编辑：我保存了.xls（以前的.xlsx）相同的文件，并没有问题。 可能是与.ShiftRows XSSFWorkbook的唯一… …将继续保持你张贴。
这个问题在NPOI V2.3.0中得到了解决 。
我已经尝试过了。
