Почему инициализатор не работает для воссоздания событий, если они были удалены ⇐ C#

[Anonymous]

Помогите мне понять следующую проблему. У меня есть событие numericupdown_valuechanged, которое работает. Если я нажимаю кнопку1, я удаляю это событие из числового. Так что это событие больше не работает. Когда я нажимаю кнопку2, я вызываю метод инициализации.numericUpDown1.ValueChanged += numericUpDown1_ValueChanged;

мой код
public partial class Form1 : Form {
public Form1() {
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e) {
numericUpDown1.ValueChanged -= numericUpDown1_ValueChanged;
}

private void numericUpDown1_ValueChanged(object sender, EventArgs e) {
Console.WriteLine(numericUpDown1.Value);
}

private void button2_Click(object sender, EventArgs e) {
InitializeComponent();
}
}

my .designer file
partial class Form1 {
///
/// Required designer variable.
///
private System.ComponentModel.IContainer components = null;

///
/// Clean up any resources being used.
///
/// true if managed resources should be disposed; otherwise, false.
protected override void Dispose(bool disposing) {
if (disposing && (components != null)) {
components.Dispose();
}
base.Dispose(disposing);
}
