推荐答案

在c＃中的datagridview中生成序列号

private void metroGrid1_RowPostPaint(object sender, DataGridViewRowPostPaintEventArgs e)
    {
        using (SolidBrush b = new SolidBrush(((DataGridView)sender).RowHeadersDefaultCellStyle.ForeColor))
        {
            e.Graphics.DrawString((e.RowIndex + 1).ToString(), e.InheritedRowStyle.Font, b, e.RowBounds.Location.X + 10, e.RowBounds.Location.Y + 4);
        }
    }

dataGridView1.DataBindingComplete += (o, e) =>
    {
        foreach (DataGridViewRow row in dataGridView1.Rows)
            row.HeaderCell.Value = (row.Index + 1).ToString();
    };
