如何使用OpenXML從Excel工作表中檢索選項卡名稱

Question

我有一個電子表格文檔，其中包含182列。 我需要將電子表格數據放在數據表中，逐個標簽，但我需要找出，因為我正在添加每個選項卡中的數據，選項卡名稱是什么，並將選項卡名稱添加到數據表中的列。

這就是我設置數據表的方法。

然后我循環工作簿並向下鑽取到sheetData對象並遍歷每一行和每列，獲取單元格數據。

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，在我用於數據表的字符串數組的末尾，我需要添加選項卡名稱。 當我在Open XML中的表格中循環時，如何找到選項卡名稱？

到目前為止，這是我的代碼：

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;

請注意：我以前從“list”的InnerXML屬性中獲取了選項卡名稱

OpenXmlElementList list = sheets.ChildElements;

但是我注意到，當我在電子表格中循環時，它沒有按正確的順序獲取選項卡名稱。

這是一個方便的幫助方法，以獲取與WorksheetPart對應的Sheet：

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);
}

然后你可以從工作表Name-property獲取名稱：

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

...這將是OP提到的“標簽名稱”。

對於記錄，相反的方法看起來像：

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

...並且我們還可以添加以下方法：

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)));
}

現在，您可以輕松枚舉所有工作表，包括其名稱。

如果您願意，可以將其全部放入字典中進行基於名稱的查找：

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

...或者如果您只想要一個特定的表格：

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

（然后調用GetWorkSheetFromSheet獲取相應的工作表。）

Answer 2

工作表名稱存儲在Sheets元素的WorkbookPart中，該元素具有元素Sheet子元素，對應於Excel文件中的每個工作表。 您所要做的就是從Sheets元素中獲取正確的索引，這將是您在循環中使用的工作Sheet 。 我在下面添加了一段代碼來做你想要的。

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()
