如何更改此方法以返回字符串數組

我想要一個數組或列表，其中包含電子表格中所有單元格的所有值。有一定數量的列，但有任意數量的行。這是我從msdn.com得到的方法，我想知道是否可以修改它以返回電子表格中的所有值，或者如果有辦法讓所有包含值的單元格，然後使字符串生成器迭代通過每個地址。真的，我試圖讓我的頭在這個SDK，希望你們可以給我一些見解。下面是該方法：如何更改此方法以返回字符串數組

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

{ 字符串值= 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;

}

我真的很感激任何幫助。

下面的代碼塊抓住所有的細胞和過濾下來，只是我們試圖找到一個...

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

如果刪除Where(...)，應該給你的所有單元格...

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

現在，你有，你可以採取的代碼塊的if (theCell != null) { ... }塊內，使之法，需要一個Cell（我把它叫做ProcessCell在這裏，它會需要一個static功能返回一個string），並把它稱爲foreach循環中，像這樣：

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

，然後就返回你的結果！

return results;

技術上我沒有回答你的問題，因爲返回類型是List<String>而不是數組，但我認爲你可以計算的那部分，如果它真的有必要;）
