无法使用VS C ++插入MySqL数据库

Question

您好我正在制作一个Visual c ++应用程序，但是当我尝试将数据写入数据库时​​，它只在主键中写入“0”，其余为空值，但我很确定我从文本框中获取数据，所以我不知道发生了什么。 以下是“添加”按钮事件的代码：

private: System::Void btn_add_Click(System::Object^  sender, System::EventArgs^  e) {       
        Worker^ pwork = gcnew Worker();
        pwork->dni = Int32::Parse(txt_dni->Text);
        pwork->lastname = txt_lastname->Text;
        pwork->slastname = txt_slastname->Text;
        pwork->fname = txt_name->Text;
        pwork->sname = txt_sname->Text;
        pwork->post = txt_post->Text;

        WorkerManager^ manager = gcnew WorkerManager();
        manager->AddWorker(pwork); 

        RefreshWorkerListBox();//this doesn't matter
    }

我知道在进入“AddWorker”之前，'pwork'包含我想要的所有信息，我已经检查过了，但在AddWorker中我不知道发生了什么，请在这里提供一些帮助：

void WorkerManager::AddWorker(Worker^ pwork){   
    MySqlConnection^ conn = nullptr;
    conn = gcnew MySqlConnection();
    conn->ConnectionString = "Database=produccion;Data Source=localhost;User Id=root;Password=*******";
    conn->Open();

    //Sentencia

    MySqlCommand^ comm = gcnew MySqlCommand();

    comm->CommandText = "INSERT INTO personalsfc " + "VALUES(dni,lastname,slastname,name,sname,post)";

    MySqlParameter^ p0 = gcnew MySqlParameter("dni", MySqlDbType::Int32);
    MySqlParameter^ p1 = gcnew MySqlParameter("lastname", MySqlDbType::VarChar);
    MySqlParameter^ p2 = gcnew MySqlParameter("slastname", MySqlDbType::VarChar);
    MySqlParameter^ p3 = gcnew MySqlParameter("name", MySqlDbType::VarChar);
    MySqlParameter^ p4 = gcnew MySqlParameter("sname", MySqlDbType::VarChar);
    MySqlParameter^ p5 = gcnew MySqlParameter("post", MySqlDbType::VarChar);

    p0->Value = pwork->dni;
    p1->Value = pwork->lastname;
    p2->Value = pwork->slastname;
    p3->Value = pwork->fname;
    p4->Value = pwork->sname;
    p5->Value = pwork->post;

    comm->Parameters->Add(p0);
    comm->Parameters->Add(p1);
    comm->Parameters->Add(p2);
    comm->Parameters->Add(p3);
    comm->Parameters->Add(p4);
    comm->Parameters->Add(p5);

    comm->Connection = conn;
    comm->ExecuteNonQuery();
    conn->Close();
}
