TextBox[], Label[]. Как их сделать глобальными?

TextBox[] questions = { textBox2, textBox3, textBox4, textBox5, textBox6, textBox7, textBox8, textBox9, textBox10, textBox11 };
            TextBox[] answers = { textBox12, textBox13, textBox14, textBox15, textBox16, textBox17, textBox18, textBox19, textBox20, textBox21 };
            Label[] lquestions = { label1, label2, label3, label4, label5, label6, label7, label8, label9, label10 };
            Label[] lanswers = { label11, label12, label13, label14, label15, label16, label17, label18, label19, label20 };

 public partial class Form2 : Form
    {
 
 TextBox[] questions = { textBox2, textBox3, textBox4, textBox5, textBox6, textBox7, textBox8, textBox9, textBox10, textBox11 };
        TextBox[] answers = { textBox12, textBox13, textBox14, textBox15, textBox16, textBox17, textBox18, textBox19, textBox20, textBox21 };
        Label[] lquestions = { label1, label2, label3, label4, label5, label6, label7, label8, label9, label10 };
        Label[] lanswers = { label11, label12, label13, label14, label15, label16, label17, label18, label19, label20 };
 
}

public partial class Form1 : Form
{
    private Label[] _labels;
 
    public Form1()
    {
        InitializeComponent();
 
        this._labels = { this.label1, this.label2, this.label3, this.label4, this.label5 };
        ...

public partial class Form2 : Form
{
 
    TextBox[] questions; //объявляем как поле класса
 
    public Form2()
    {
        InitializeComponent();
        questions = new TextBox[] { textBox2, textBox3, textBox4, ... }; //инициализируем
    }
    
    //...
 
}
