Error inserting MYSQL by data grid view

The code is as follows, I'm doing an insert from the values of a data grid view

                foreach (DataGridViewRow row in dgvCON.Rows)
                {
                        MySqlCommand cmd = new MySqlCommand();
                        cmd = conectabanco.CreateCommand();
                        if (row.IsNewRow) continue;
                        cmd.Parameters.AddWithValue("@IdProd", row.Cells["Id"].Value);
                        cmd.Parameters.AddWithValue("@QtdProd", row.Cells["Quantidade"].Value);
                        cmd.Parameters.AddWithValue("@NomeProd", row.Cells["Nome"].Value);
                        cmd.Parameters.AddWithValue("@PrecoUnitProd", row.Cells["R$ Unidade"].Value);
                        cmd.Parameters.AddWithValue("@TotalListaConsu", row.Cells["Total"].Value);
                        cmd.CommandText = "INSERT INTO listaconsumo(IdCon, IdProd, QtdProd, PrecoUnitProd, " +
                        "totalListaConsu)VALUES("+idconsumo+", @IdProd, @QtdProd, @NomeProd, @PrecoUnitProd, @totalListaConsu)";

                    cmd.ExecuteNonQuery();
                }

The problem is that when executing Sql, it sends pro insert the value "@IDProd" itself, rather than being replaced by the value of the datagridview
