如何在DGV单元格格式化为C2格式时将值传递给DGV单元格

private void dataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
    if (e.ColumnIndex == yourColumnIndex && e.RowIndex != -1) // 指定要格式化的列
    {
        DataGridViewCell cell = dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex];
        if (cell.Value != null && cell.Value.GetType() == typeof(double))
        {
            double value = (double)cell.Value;
            cell.Value = value.ToString("C2"); // 格式化为C2格式
            e.FormattingApplied = true;
        }
    }
}
