OpenXmlReader未从excel .xlsx工作表中提取所有单元格内容

我有一些代码最初来自SO并转换为VB Net：Using OpenXmlReader

我的代码循环遍历工作表的前14行，没有任何问题但是后来找不到任何单元格。

reader.ElementType似乎在14之后找到 rows （如果reader.ElementType是GetType（Row）那么），但不再有 cells （GetType（Cell））< / p>

提取的最后一个单元格是L14，但excel文件的单元格内容最高为L29。

    sbTxtFromFile.Length = 0

            Dim workbookPart As WorkbookPart = spreadsheetDocument__1.WorkbookPart

            Dim sharedStringItemsArray As SharedStringItem() = workbookPart.SharedStringTablePart.SharedStringTable.Elements(Of SharedStringItem)().ToArray()

            Dim sheets As DocumentFormat.OpenXml.Spreadsheet.Sheets = spreadsheetDocument__1.WorkbookPart.Workbook.Sheets

            ' For each sheet, display the sheet information.

虽然不是我想要的答案（我相信我仍然可以使用原始代码返回所有单元格），但我通过删除找到行的外部“IF”语句解决了我的问题，孩子和循环所有的兄弟姐妹。代码现在只查找单元格并返回值。

'Previous Code

While reader.Read()
    If reader.ElementType Is GetType(Row) Then
        reader.ReadFirstChild()
            Do
                If reader.ElementType Is GetType(Cell) Then
                    'Code Here
                End If
           Loop While reader.ReadNextSibling()
    End If
End While


'New Code   
While reader.Read()
    'If reader.ElementType Is GetType(Row) Then
    'reader.ReadFirstChild()
    'Do
    If reader.ElementType Is GetType(Cell) Then
        Do
            'Code Here
        Loop While reader.ReadNextSibling()

    'Loop While reader.ReadNextSibling()
