以下は、XLSX を作成し、いくつかのデータを含む 2 つのワークシートを追加します。次に、後で名前(またはできればID)に基づいてスプレッドシートを取得できるようにしたいので、後でシートを追加/変更できます。以下のコードが不完全なシートを再度取得する方法に行き詰まっています。
Sub Main()
Using doc As SpreadsheetDocument = SpreadsheetDocument.Create(System.IO.Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "c:\temp\fubar.xlsx"), SpreadsheetDocumentType.Workbook)
Dim currSheet As WorksheetPart
' create the workbook
doc.AddWorkbookPart()
doc.WorkbookPart.Workbook = New Workbook()
doc.WorkbookPart.Workbook.AppendChild(New Sheets())
currSheet = InsertWorksheet(doc.WorkbookPart, "First")
currSheet.Worksheet.First().AppendChild(New Row())
currSheet.Worksheet.First().First().AppendChild(New Cell() With { _
.CellValue = New CellValue("1") _
})
currSheet = InsertWorksheet(doc.WorkbookPart, "Second")
currSheet.Worksheet.First().AppendChild(New Row())
currSheet.Worksheet.First().First().AppendChild(New Cell() With { _
.CellValue = New CellValue("1") _
})
For Each s As Sheet In doc.WorkbookPart.Workbook.Sheets
System.Diagnostics.Debug.WriteLine(s.Id)
System.Diagnostics.Debug.WriteLine(s.SheetId)
Next
cursheet = ... 'Get worksheetpart with name "First"
cursheet = ... 'Get worksheet with sheetid = 2
doc.WorkbookPart.Workbook.Save()
End Using
End Sub
Private Function InsertWorksheet(ByVal workbookPart As WorkbookPart, SheetName As String) As WorksheetPart
' Add a new worksheet part to the workbook.
Dim newWorksheetPart As WorksheetPart = workbookPart.AddNewPart(Of WorksheetPart)()
newWorksheetPart.Worksheet = New Worksheet(New SheetData)
newWorksheetPart.Worksheet.Save()
Dim sheets As Sheets = workbookPart.Workbook.GetFirstChild(Of Sheets)()
Dim relationshipId As String = workbookPart.GetIdOfPart(newWorksheetPart)
' Get a unique ID for the new sheet.
Dim sheetId As UInteger = 1
If (sheets.Elements(Of Sheet).Count() > 0) Then
sheetId = sheets.Elements(Of Sheet).Select(Function(s) s.SheetId.Value).Max() + 1
End If
' Add the new worksheet and associate it with the workbook.
Dim sheet As Sheet = New Sheet
sheet.Id = relationshipId
sheet.SheetId = sheetId
sheet.Name = sheetName
sheets.Append(sheet)
workbookPart.Workbook.Save()
Return newWorksheetPart
End Function
