NPOI/POI Excel Lib ISheet.ShiftRowsインデックス範囲外の例外

Question

私はNPOIで.ShiftRowsを使用してExcelファイルに新しい行を挿入しています。しかし、新しい行を挿入するために行を下にシフトしようとすると、特定のファイルにSystem.ArgumentOutOfRangeExceptionが表示されます。これらは、私が投入している別の会社の一般的なファイルなので、最後の行がどこにあるかをNPOIが知っているので、それに関係なく実行することができます。

この場合、16〜458行をシフトダウンしていて、範囲外の例外が発生しました。

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.

私はこの仕事をするためにhereからNPOIにいくつかのPOIコードを変更しました。

CopyRow機能：

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); 
     } 
    } 
} 

は、誰もが前NPOIやPOIで、この問題に遭遇していますか？

NPOI v2.2.1を使用しています。

編集：.xls（以前の.xlsx）と同じファイルを保存しても、問題はありませんでした。たぶんXSSFWorkbookのための.ShiftRowsとの関係は...あなたの投稿を続けていきます。

Answer 1

この問題は、NPOI V2.3.0で修正されています。

私はそれを試しました。
