Question

大家好，你能帮我解决这个错误当我插入数据库时，会出现Message框那说

＆＃34;从对象类型到已知对象不存在映射 System.Windows.Forms.Textbox本机托管提供程序类型＆＃34;

和错误哪里有错误代码？因为我刚刚完成移动旧数据库并因为数据类型错误

而创建了一个新数据库

我有一些代码插入照片

private void button2_Click(object sender, EventArgs e)
    {
        lblRightorFalse.Text = "False";

        try{
            string dProduksi = DateTime.Parse(dtmProduksi.Text).ToString("yyyy-MM-dd");

            byte[] image = null;
            FileStream fs = new FileStream(this.txtLink.Text, FileMode.Open, FileAccess.Read);
            BinaryReader br = new BinaryReader(fs);
            image = br.ReadBytes((int)fs.Length);

            con.Open();
            cmd = new SqlCommand("insert into Produksi (IDProduksi,TanggalProduksi,NamaKaryawan,KeteranganPhoto,Photo,Verifikasi,IDPhoto,Jenis_Kanvas,Ukuran_Photo) Values(@IDProduksi,@TanggalProduksi,@NamaKaryawan,@KeteranganPhoto,@Photo,@IDPhoto,@Jenis_Kanvas,@Ukuran_Photo)", con);
            cmd.Parameters.AddWithValue("@IDProduksi", txtIdpro.Text);
            cmd.Parameters.AddWithValue("@IDPhoto", txtIdPhoto.Text);
            cmd.Parameters.AddWithValue("@TanggalProduksi", dProduksi);
            cmd.Parameters.AddWithValue("@NamaKaryawan", txtNamaKaryawan.Text);
            cmd.Parameters.AddWithValue("@KeteranganPhoto", rxtKtrphoto.Text);
            cmd.Parameters.AddWithValue("@Photo", image);
            cmd.Parameters.AddWithValue("@Verifikasi",lblRightorFalse.Text);
            cmd.Parameters.AddWithValue("@Jenis_Kanvas", txtJenisKertas.Text);

            cmd.ExecuteNonQuery();
            MessageBox.Show("Insert telah di jalankan");

            showgridview();
            clear();
            }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message);
        }
