Question

我想要一个包含电子表格中所有单元格的所有值的数组或列表。有一定数量的列，但有任意数量的行。这是我从msdn.com获得的一种方法，我想知道是否可以修改它以返回电子表格中的所有值，或者是否有办法获取所有具有值的单元格，然后使字符串生成器迭代通过每个地址。真的，我正试图了解这个SDK，并希望你们能给我一些见解。这是方法：

public static string GetCellValue(string fileName, 
string sheetName, 
string addressName)

{ string value = null;

// Open the spreadsheet document for read-only access.
using (SpreadsheetDocument document = 
    SpreadsheetDocument.Open(fileName, false))
{
    // Retrieve a reference to the workbook part.
    WorkbookPart wbPart = document.WorkbookPart;

    // Find the sheet with the supplied name, and then use that 
    // Sheet object to retrieve a reference to the first worksheet.
    Sheet theSheet = wbPart.Workbook.Descendants<Sheet>().
      Where(s => s.Name == sheetName).FirstOrDefault();

    // Throw an exception if there is no sheet.
    if (theSheet == null)
    {
        throw new ArgumentException("sheetName");
    }

    // Retrieve a reference to the worksheet part.
    WorksheetPart wsPart = 
        (WorksheetPart)(wbPart.GetPartById(theSheet.Id));

    // Use its Worksheet property to get a reference to the cell 
    // whose address matches the address you supplied.
    Cell theCell = wsPart.Worksheet.Descendants<Cell>().
      Where(c => c.CellReference == addressName).FirstOrDefault();

    // If the cell does not exist, return an empty string.
    if (theCell != null)
    {
        value = theCell.InnerText;

        // 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 (theCell.DataType != null)
        {
            switch (theCell.DataType.Value)
            {
                case CellValues.SharedString:

                    // For shared strings, look up the value in the
                    // shared strings table.
                    var stringTable = 
                        wbPart.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;

}

我非常感谢任何帮助。

以下代码块抓取所有单元格并将其过滤到我们想要查找的单元格中...

Cell theCell = wsPart.Worksheet.Descendants<Cell>().
  Where(c => c.CellReference == addressName).FirstOrDefault();

如果删除Where(...)，则应该为您提供所有单元格...

var cells = wsPart.Worksheet.Descendants<Cell>();

现在您已经拥有了这个，您可以在if (theCell != null) { ... }块中获取代码块，使其成为Cell的方法（我在这里称之为ProcessCell，它是'需要是一个返回static的{{1}}函数，并在string循环中调用它，如下所示：

foreach

然后只返回结果！

var results = new List<String>();
foreach cell in cells
{
    results.Add(ProcessCell(cell));
}

从技术上讲，我没有回答你的问题，因为返回类型是return results;而不是数组，但我认为如果真的有必要，你可以找出那部分;）
