    foreach (DataGridViewCell cell in row.Cells)
    {
        if (cell.Value != null && cell.Value.ToString() == targetValue)
        {
            // 找到目标值
            // 进行相关操作
        }

foreach (DataGridViewRow row in dataGridView1.SelectedRows)
{
    foreach (DataGridViewCell cell in row.Cells)
    {
        string cellValue = cell.Value.ToString();
        // 处理每个单元格的值
    }
}

DataGridViewCell selectedCell = dataGridView1.CurrentCell;
string selectedCellValue = selectedCell.Value.ToString();
