public class ExcelReader
{
    public static DataTable ReadExcel(string filePath, string sheetName)
    {
        DataTable dt = new DataTable();

        using (var fs = File.Open(filePath, FileMode.Open, FileAccess.Read))
        {
            var workbook = new XSSFWorkbook(fs);
            var sheet = workbook.GetSheet(sheetName);

            // 获取列标题
            var headerRow = sheet.GetRow(0);
            foreach (var cell in headerRow.Cells)
            {
                dt.Columns.Add(cell.ToString());
            }

            // 读取数据行
            for (int i = sheet.FirstRowNum + 1; i <= sheet.LastRowNum; i++)
            {
                var row = sheet.GetRow(i);
                var newRow = dt.NewRow();

                // 检查特定列的值并选择行
                if (row.GetCell(0).ToString() == "某个特定列的值")
                {
                    for (int j = row.FirstCellNum; j < row.LastCellNum; j++)
                    {
                        newRow[j] = row.GetCell(j).ToString();
                    }

                    dt.Rows.Add(newRow);
                }
            }
        }

        return dt;
    }
}

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        OpenFileDialog openFileDialog1 = new OpenFileDialog();
        openFileDialog1.Filter = "Excel文件|*.xlsx;*.xls";
        openFileDialog1.Title = "选择Excel文件";
        
        if (openFileDialog1.ShowDialog() == DialogResult.OK)
        {
            string filePath = openFileDialog1.FileName;
            string sheetName = "Sheet1"; // 根据实际情况设置sheet名称

            DataTable dt = ExcelReader.ReadExcel(filePath, sheetName);
            dataGridView1.DataSource = dt;
        }
    }
}
