Question

我有一个Excel 2010电子表格，其中包含3个名为Sheet1，Sheet2和Sheet3的工作表。

我正在尝试按名称获取对工作表的引用。

我正在使用代码：

using (SpreadsheetDocument myWorkbook = SpreadsheetDocument.Open(FileName, true))
{
    //Access the main Workbook part, which contains all references 
    WorkbookPart workbookPart = myWorkbook.WorkbookPart;

    WorksheetPart worksheetPart = workbookPart.WorksheetParts.Last(); 

    // this gives me Sheet1
    SheetData sheetData = worksheetPart.Worksheet.GetFirstChild<SheetData>();
}

我正在尝试获取Sheet2的引用，但我找不到这样做的方法。

我越来越近了，但我还没到那里：

var x = workbookPart.Workbook.Sheets.Where(s=> s.GetAttribute("name", "").Value == "Sheet2").FirstOrDefault();

这是我对工作表的引用，而不是工作表中的数据

Answer 1

你真正想要的是WorksheetPart，它包含你正在寻找的SheetData。抓取Sheets下的Workbook只会为您提供有关工作表的某些元数据。这是一个关于如何抓取WorksheetPart的示例（随意添加错误检查，因为我假设sheetName已经存在，只需调用First而不是FirstOrDefault ）

public WorksheetPart GetWorksheetPart(WorkbookPart workbookPart, string sheetName)
{
    string relId = workbookPart.Workbook.Descendants<Sheet>().First(s => sheetName.Equals(s.Name)).Id;
    return (WorksheetPart)workbookPart.GetPartById(relId);
}

然后只需使用上面的代码来获取正确的SheetData引用，您就可以从那里找到所需的数据。

以下是处理具有特定标签或图纸名称的电子表格并将其转储为CSV之类的代码。（我选择了一个管道而不是逗号）。

我希望从单元格中获取值更容易，但我认为这是我们所坚持的。您可以看到我参考了MSDN文档，其中包含了大部分代码。这就是微软推荐的。

    /// <summary>

    /// </summary>
    [Test]
    public void WriteOutExcelFile()
    {
        var fileName = "ExcelFiles\\File_With_Many_Tabs.xlsx";
        var sheetName = "Submission Form"; // Existing tab name.
        using (var document = SpreadsheetDocument.Open(fileName, isEditable: false))
        {
            var workbookPart = document.WorkbookPart;
            var sheet = workbookPart.Workbook.Descendants<Sheet>().FirstOrDefault(s => s.Name == sheetName);
            var worksheetPart = (WorksheetPart)(workbookPart.GetPartById(sheet.Id));
            var sheetData = worksheetPart.Worksheet.Elements<SheetData>().First();

            foreach (var row in sheetData.Elements<Row>())
            {
                foreach (var cell in row.Elements<Cell>())
                {
                    Console.Write("|" + GetCellValue(cell, workbookPart));
                }
                Console.Write("\n");
            }
        }
    }

    /// <summary>
    /// Got code from: https://msdn.microsoft.com/en-us/library/office/hh298534.aspx
    /// </summary>
    /// <param name="cell"></param>

    /// <returns></returns>
    private string GetCellValue(Cell cell, WorkbookPart workbookPart)
    {
        if (cell == null)
        {
            return null;
        }

        var value = cell.CellFormula != null
            ? cell.CellValue.InnerText 
            : cell.InnerText.Trim();

        // If the cell represents an integer number, you are done. 
        // For dates, this code returns the serialized value that 
        // represents the date. The code handles strings and 
        // Booleans individually. For shared strings, the code 
        // looks up the corresponding value in the shared string 
        // table. For Booleans, the code converts the value into 
        // the words TRUE or FALSE.
        if (cell.DataType == null)
        {
            return value;
        }
        switch (cell.DataType.Value)
        {
            case CellValues.SharedString:

                // For shared strings, look up the value in the
                // shared strings table.
                var stringTable =
                    workbookPart.GetPartsOfType<SharedStringTablePart>()
                        .FirstOrDefault();

                // If the shared string table is missing, something 
                // is wrong. Return the index that is in
                // the cell. Otherwise, look up the correct text in 
                // the table.
                if (stringTable != null)
                {
                    value =
                        stringTable.SharedStringTable
                            .ElementAt(int.Parse(value)).InnerText;
                }
                break;

            case CellValues.Boolean:
                switch (value)
                {
                    case "0":
                        value = "FALSE";
                        break;
                    default:
                        value = "TRUE";
                        break;
                }
                break;
        }
        return value;
    }
