    [Help] How to insert data from the textBox to MySQL Database in C#

    I want to insert data from the textBox to MySQL Database, but the data can't be inserted into the database. Here is the code snipped that I have created.
    private void button6_Click(object sender, EventArgs e)
    {
    string connectionSQL = "server=localhost;database=db_junisman_kulit;uid=root;password=;";
    MySqlConnection conn = new MySqlConnection();
    double no_simpan = 0;
    try
    {
    conn.Open();
    MySqlCommand cmd = new MySqlCommand("INSERT INTO tb_backorder (no_simpan,tanggal_simpan,jumlah_rata_rata,lead_time,ongkos_pesan,harga_barang,ongkos_simpan,ongkos_kekurangan_barang,jumlah_pemesanan,reorder_point,safety_stock,persentase_pelayanan,ongkos_total) VALUES ('" + no_simpan + "', '" + DateTime.Now.ToString("yyyyMMdd") + "', '" + textBox1.Text + "', '" + textBox3.Text + "', '" + textBox5.Text + "', '" + textBox6.Text + "', '" + textBox7.Text + "', '" + textBox8.Text + "', '" + textBox9.Text + "', '" + textBox10.Text + "', '" + textBox11.Text + "', '" + textBox12.Text + "', '" + textBox13.Text + "')", conn);
    conn.Close();
    }

    catch (MySqlException ex)
    {

    MessageBox.Show("Can't connect to database\n" + ex.ToString());
    }
    }

    for no_simpan, this data is not from the textBox but a sequence number that is automatically ordered if the data is stored to the database.

    and for tanggal_simpan is the date when the data is stored to the database.
    How do I write the correct code to insert the data from the textBox into the MySQL database? I use a MySQL database.

    I have attached form display and tb_backorder picture below
    Thank You in Advance,
