Write data from two Datagridview to the Sql Server database

Question

I’m not able to record the data that are in two dataGridView, the data that are in the two Datagridview are in a single Class, I have a code ready but would serve only for a Datagrid, in the same for wanted to put another Grid if possible, or if there were any other way to do it, I would appreciate the help.

 public void InserirItensOs()
    {
        try
        {
            if (DtGridServico.Rows.Count > 1)
            {
                for (int i = 0; i < DtGridServico.Rows.Count - 1; i++) //quero colocar outro GridViews no for.
                {
                    DetalheOrdemServico ordem = new DetalheOrdemServico();
                    ordem.OrdemServicoId = Convert.ToInt32(DtGridServico.Rows[i].Cells[0].Value);
                    ordem.NomeServico = DtGridServico.Rows[i].Cells[1].Value.ToString();
                    ordem.NomeMecanico = DtGridServico.Rows[i].Cells[2].Value.ToString();
                    ordem.VlrServDetalhe = Convert.ToDecimal(DtGridServico.Rows[i].Cells[3].Value);
                    ordem.ServicoId = Convert.ToInt32(DtGridServico.Rows[i].Cells[4].Value);

                    context.detalheOrdemServicos.Add(ordem);
                }
            }
