如何删除datagridview中具有相同值的行

private void RemoveDuplicateRows(DataGridView dataGridView)
{
    List<int> rowsToRemove = new List<int>();

    for (int i = 0; i < dataGridView.Rows.Count - 1; i++)
    {
        DataGridViewRow row1 = dataGridView.Rows[i];

        for (int j = i + 1; j < dataGridView.Rows.Count; j++)
        {
            DataGridViewRow row2 = dataGridView.Rows[j];

            bool duplicateRow = true;

            for (int k = 0; k < row1.Cells.Count; k++)
            {
                if (!row1.Cells[k].Value.Equals(row2.Cells[k].Value))
                {
                    duplicateRow = false;
                    break;
                }
            }

            if (duplicateRow)
            {
                rowsToRemove.Add(j);
            }
        }
    }

    // 删除被标记的行
    foreach (int rowIndex in rowsToRemove)
    {
        dataGridView.Rows.RemoveAt(rowIndex);
    }
}
