如何使用 OpenXML 从 Excel 工作表中检索选项卡名称

Question

我有一个包含 182 列的电子表格文档。我需要将电子表格数据逐个选项卡地放入数据表中，但我需要在从每个选项卡添加数据时找出选项卡名称是什么，并将选项卡名称添加到数据表中的列中.

这就是我设置数据表的方式。

然后我在工作簿中循环并深入到sheetData 对象并遍历每一行和每一列，获取单元格数据。

DataTable dt = new DataTable();
for (int i = 0; i <= col.GetUpperBound(0); i++)
{
    try
    {
        dt.Columns.Add(new DataColumn(col[i].ToString(), typeof(string)));
    }
    catch (Exception e)
    {
        MessageBox.Show("Uploader  Error" + e.ToString());
        return null;
    }
}

dt.Columns.Add(new DataColumn("SheetName", typeof(string)));

但是，在我用于数据表的字符串数组的末尾，我需要添加选项卡名称。当我在 Open XML 的工作表中循环时，如何找出选项卡名称？

到目前为止，这是我的代码：

using (SpreadsheetDocument spreadSheetDocument = 
           SpreadsheetDocument.Open(Destination, false))
{
    WorkbookPart workbookPart = spreadSheetDocument.WorkbookPart;
    Workbook workbook = spreadSheetDocument.WorkbookPart.Workbook;

    Sheets sheets = 
        spreadSheetDocument
            .WorkbookPart
            .Workbook
            .GetFirstChild<DocumentFormat.OpenXml.Spreadsheet.Sheets>();

    OpenXmlElementList list = sheets.ChildElements;

    foreach (WorksheetPart worksheetpart in workbook.WorkbookPart.WorksheetParts)
    {
        Worksheet worksheet = worksheetpart.Worksheet;

        foreach (SheetData sheetData in worksheet.Elements<SheetData>())
        {
            foreach (Row row in sheetData.Elements())
            {
                string[] thisarr = new string[183];
                int index = 0;
                foreach (Cell cell in row.Elements())
                {
                    thisarr[(index)] = GetCellValue(spreadSheetDocument, cell);
                    index++;
                }
                thisarr[182] = ""; //need to add tabname here
                if (thisarr[0].ToString() != "")
                {
                    dt.Rows.Add(thisarr);
                }
            }
        }
    }
}

return dt;

请注意：我之前确实从“列表”的 InnerXML 属性中获取了选项卡名称

OpenXmlElementList list = sheets.ChildElements;

但是我注意到，当我在电子表格中循环时，它没有以正确的顺序获取选项卡名称。

这是一个方便的帮助方法来获取对应于 WorksheetPart 的工作表：

public static Sheet GetSheetFromWorkSheet
    (WorkbookPart workbookPart, WorksheetPart worksheetPart)
{
    string relationshipId = workbookPart.GetIdOfPart(worksheetPart);
    IEnumerable<Sheet> sheets = workbookPart.Workbook.Sheets.Elements<Sheet>();
    return sheets.FirstOrDefault(s => s.Id.HasValue && s.Id.Value == relationshipId);
}

然后你可以从表格 Name-property 中获取名称：

Sheet sheet = GetSheetFromWorkSheet(myWorkbookPart, myWorksheetPart);
string sheetName = sheet.Name;

...这将是 OP 引用的“选项卡名称”。

为了记录，相反的方法如下所示：

public static Worksheet GetWorkSheetFromSheet(WorkbookPart workbookPart, Sheet sheet)
{
    var worksheetPart = (WorksheetPart)workbookPart.GetPartById(sheet.Id);
    return worksheetPart.Worksheet;
}

...我们还可以添加以下方法：

public static IEnumerable<KeyValuePair<string, Worksheet>> GetNamedWorksheets
    (WorkbookPart workbookPart)
{
    return workbookPart.Workbook.Sheets.Elements<Sheet>()
        .Select(sheet => new KeyValuePair<string, Worksheet>
            (sheet.Name, GetWorkSheetFromSheet(workbookPart, sheet)));
}

现在您可以轻松枚举所有工作表，包括它们的名称。

如果您愿意，可以将其全部放入字典中进行基于名称的查找：

IDictionary<string, WorkSheet> wsDict = GetNamedWorksheets(myWorkbookPart)
    .ToDictionary(kvp => kvp.Key, kvp => kvp.Value);

...或者如果您只想要一个特定的工作表名称：

public static Sheet GetSheetFromName(WorkbookPart workbookPart, string sheetName)
{
    return workbookPart.Workbook.Sheets.Elements<Sheet>()
        .FirstOrDefault(s => s.Name.HasValue && s.Name.Value == sheetName);
}

（然后调用GetWorkSheetFromSheet获取对应的Worksheet。）

Answer 2

工作表名称存储在 Sheets 元素中的 WorkbookPart 中，该元素具有元素 Sheet 的子元素，该元素对应于 Excel 文件中的每个工作表。您所要做的就是从Sheets 元素中获取正确的索引，这将是您在循环中的Sheet。我在下面添加了一段 sn-p 代码来做你想做的事。

int sheetIndex = 0;
foreach (WorksheetPart worksheetpart in workbook.WorkbookPart.WorksheetParts)
{                     
    Worksheet worksheet = worksheetpart.Worksheet;

    // Grab the sheet name each time through your loop
    string sheetName = workbookPart.Workbook.Descendants<Sheet>().ElementAt(sheetIndex).Name;

    foreach (SheetData sheetData in worksheet.Elements<SheetData>())
    {

       ...
    }
    sheetIndex++;
}

    Using spreadsheetDocument As SpreadsheetDocument = spreadsheetDocument.Open("D:\Libro1.xlsx", True)

        Dim workbookPart As WorkbookPart = spreadsheetDocument.WorkbookPart

        workbookPart.Workbook.Descendants(Of Sheet)()



        Dim worksheetPart As WorksheetPart = workbookPart.WorksheetParts.Last
        Dim text As String



        For Each Sheet As Sheet In spreadsheetDocument.WorkbookPart.Workbook.Sheets
            Dim sName As String = Sheet.Name
            Dim sID As String = Sheet.Id

            Dim part As WorksheetPart = workbookPart.GetPartById(sID)
            Dim actualSheet As Worksheet = part.Worksheet

            Dim sheetData As SheetData = part.Worksheet.Elements(Of SheetData)().First

            For Each r As Row In sheetData.Elements(Of Row)()
                For Each c As Cell In r.Elements(Of Cell)()
                    text = c.CellValue.Text
                    Console.Write(text & " ")
                Next
            Next
        Next

    End Using

    Console.Read()
