製作多個OpenXML工作表副本的錯誤

Question

我有一個修改現有電子表格的程序。該程序的一部分創建特定工作表的副本。要創建一個副本，程序運行良好，生成的文件也很好，在Excel中打開時不會顯示錯誤。但是，在創建相同的工作表的兩個副本時，程序仍然運行得很好，但在Excel中打開時，出現以下錯誤就無法讀取內容：

Repaired Records: Worksheet properties from /xl/workbook.xml part (Workbook)

這裏是用來執行復制的代碼：

private void CopySheet(int sNum, int pNum, string type) 
{ 
    var tempSheet = SpreadsheetDocument.Create(new MemoryStream(), SpreadsheetDocumentType.Workbook); 
    WorkbookPart tempWBP = tempSheet.AddWorkbookPart(); 
    var part = Document.XGetWorkSheetPart(sNum); 
    var sheetData = part.Worksheet.ChildElements[5].Clone() as SheetData; 
    var merge = part.Worksheet.ChildElements[6].Clone() as MergeCells; 
    WorksheetPart tempWSP = tempWBP.AddPart<WorksheetPart>(part); 

    var copy = Document.WorkbookPart.AddPart<WorksheetPart>(tempWSP); 
    //copy.Worksheet.RemoveChild<SheetData>(copy.Worksheet.ChildElements[5] as SheetData); 
    //copy.Worksheet.InsertAt<SheetData>(sheetData, 5); 
    //copy.Worksheet.RemoveChild<MergeCells>(copy.Worksheet.ChildElements[6] as MergeCells); 
    //copy.Worksheet.InsertAt<MergeCells>(merge, 6); 
    //copy.Worksheet.SheetProperties.CodeName.Value = "Phase" + pNum + type; 

    var sheets = Document.WorkbookPart.Workbook.Sheets; 
    var sheet = new Sheet(); 
    sheet.Id = Document.WorkbookPart.GetIdOfPart(copy); 
    sheet.Name = "Phase " + pNum + " " + type; 
    sheet.SheetId = (uint)sheets.ChildElements.Count; 
    sheets.Append(sheet); 
} 

該方法利用的是.AddPart<>()執行任何部位的深層副本（和任何它引用）的事實，已經不屬於該文件中，有一個臨時表的幫助下，創建WorkSheet的所有參考部分的深層副本。

如上所述，如果該函數僅針對給定工作表被調用一次，則該工作非常有效。但是，如果它被多次調用，則在Excel中打開文件時會出現無法讀取的內容。這就是說，文件本身似乎很好，沒有丟失數據或任何東西（這將有助於弄清楚究竟是什麼錯誤），只是錯誤說有什麼問題。

被註釋掉的行是我爲解決關於.AddPart<>()的問題所必須做的「破解」，但我不會在這裏詳細討論它們，因爲我已經發布了關於此here（但我還沒有得到答覆，所以一定要回答這個問題！）。話雖如此，這些線似乎與這個當前的問題沒有關係，因爲錯誤出現有或沒有這些代碼行。

Answer 1

我注意到源文件的工作表沒有正確編號，所以他們的SheetID不是順序的（6,1,3）。因此，我的程序在使用代碼sheet.SheetID = sheets.ChildElements.Count + 1創建兩個文件副本時，將值設置爲4,5,6和7，這會導致與現有工作表發生衝突。因此，我已經修改的部分，從而該程序總是得到一個有效的ID：

// ... 
uint id = 1; 
bool valid = false; 
while (!valid) 
{ 
    uint temp = id; 
    foreach (OpenXmlElement e in sheets.ChildElements) 
    { 
     var s = e as Sheet; 
     if (id == s.SheetId.Value) 
     { 
      id++; 
      break; 
     } 
    } 
    if (temp == id) 
     valid = true; 
} 
sheet.SheetId = id; 
//... 

有了這個我sheetIDs成爲（6,1，3，2，4，5，7），並且因此不存在衝突，沒有更多的錯誤！

     CleanView(clonedSheet); 

     //Add new sheet to main workbook part 
     Sheets sheets = workbookPart.Workbook.GetFirstChild<Sheets>(); 
     Sheet copiedSheet = new Sheet();

     copiedSheet.Id = workbookPart.GetIdOfPart(clonedSheet); 
     copiedSheet.SheetId = (uint)sheets.ChildElements.Count + 1; 
     sheets.Append(copiedSheet); 
     workbookPart.Workbook.Save(); 
    } 

    static void CleanView(WorksheetPart worksheetPart)
