用C#实现excel中单元格的循环

using Excel = Microsoft.Office.Interop.Excel;

public void LoopExcelCells()
{
    Excel.Application excelApp = new Excel.Application();
    Excel.Workbook workbook = excelApp.Workbooks.Open("path_to_excel_file.xlsx");
    Excel.Worksheet worksheet = workbook.Sheets[1];

    Excel.Range range = worksheet.UsedRange;

    foreach (Excel.Range cell in range.Cells)
    {
        // 在这里处理每个单元格
        string cellValue = cell.Value.ToString();
        Console.WriteLine(cellValue);
    }

    workbook.Close();
    excelApp.Quit();
}
