搜索電子表格中的輸入字符串

Question

我正在使用Open XML SDK打開Excel文件（xlsx），我想要查找從外部傳遞的特定字符串或整數以檢查電子表格中值的重複項。

如何在電子表格的所有單元格中搜索輸入字符串？

using DocumentFormat.OpenXml.Packaging; 
using DocumentFormat.OpenXml.Spreadsheet; 

namespace ConsoleApplication3

    class Program

     static void Main(string[] args) 
     { 
      using (SpreadsheetDocument document = SpreadsheetDocument.Open(@"C:\Users\user\Desktop\Book1.xlsx", true)) 
      { 
       Sheet sheet = document.WorkbookPart.Workbook.Descendants<Sheet>().First<Sheet>(); 
       Worksheet worksheet = ((WorksheetPart)document.WorkbookPart.GetPartById(sheet.Id)).Worksheet; 
       IEnumerable<Row> allRows = worksheet.GetFirstChild<SheetData>().Descendants<Row>(); 
       foreach (Row currentRow in allRows) 
       { 
        IEnumerable<Cell> allCells = currentRow.Descendants<Cell>(); 
        foreach (Cell currentCell in allCells) 
        { 
         CellValue currentCellValue = currentCell.GetFirstChild<CellValue>(); 
         string data = null; 
         if (currentCell.DataType != null) 
         { 
          if (currentCell.DataType == CellValues.SharedString) // cell has a cell value that is a string, thus, stored else where 
          { 
           data = document.WorkbookPart.GetPartsOfType<SharedStringTablePart>().FirstOrDefault().SharedStringTable.ElementAt(int.Parse(currentCellValue.Text)).InnerText; 
          } 
         } 
         else 
         { 
          data = currentCellValue.Text; 
         } 
         Console.WriteLine(data); 

         /* 
          your code here 

           if(data.contains("myText")) 
            doSomething(); 

         */ 

        } 
       } 
      }   
     } 
    } 
}
