Как я могу вызвать событие click из другого класса?

Question

У меня есть эти два метода в 1 классе (класс CokeMachine):

public void MoneyButtonEvents() 
    { 
     Coin1.Click += new EventHandler(Coin1_ClickHandler); 
    } 

&

public void Coin1_ClickHandler(object sender, EventArgs e) 
    { 
     TotalInsertedCoins += CoinAmount1; 
     MessageBox.Show("Does this click work?"); 
    } 

А в другой класс (класс CokeForm: Form), я в здании форму для приложение. Одна часть его:

CokeMachine Machine = new CokeMachine(); 

Machine.Coin1.Text = "Test"; 
this.Controls.Add(Machine.Coin1); 

Но кнопка не показывает ничего, когда я нажимаю на него. Может ли кто-нибудь помочь мне с этим? Спасибо заранее!

Answer 1

Я не вижу ваш инициализатор для вашего CokeMachine Класс.

Попробуйте добавить это к вашему CokeMachine Класс:

public CokeMachine() 
{ 
    MoneyButtonEvents(); 
    DrinkButtonsEvents(); 
} 

Это заставит ваши обработчики, которые будут добавлены при создании класса.

Answer 2

MoneyButtonEvents никогда не вызывается.
