버튼 클릭 이벤트마다 프로그램의 특정 부분을 다시 실행하려면 어떻게합니까?

Question

코카인 기계를 만들려고하는데 문제가되지 않습니다.

버튼 클릭 이벤트가 발생할 때마다 특정 코드 블록을 다시 실행시키고 싶습니다. 어떻게해야합니까?

이 내 전체 코드입니다 :

using System; 
using System.Windows.Forms; 
using System.Drawing; 

namespace QuickSharp 
{ 
public class CokeMachine

    public Button Coke = new Button();

    public Button Fanta = new Button(); 
    public Button RedBull = new Button(); 
    public Button Juice = new Button(); 
    public Button Water = new Button(); 

    double CokeCost = 1.00; 
    double SpriteCost = 1.00; 
    double FantaCost = 1.00; 
    double RedBullCost = 2.50; 
    double JuiceCost = 2.00; 
    double WaterCost = 0.50; 

    public Button Coin1 = new Button(); 
    public Button Coin2 = new Button(); 
    public Button Coin3 = new Button(); 
    public Button Coin4 = new Button();

    public Button Coin6 = new Button(); 

    double CoinAmount1 = 0.05; 
    double CoinAmount2 = 0.10; 
    double CoinAmount3 = 0.20; 
    double CoinAmount4 = 0.50; 
    double CoinAmount5 = 1.00; 
    double CoinAmount6 = 2.00; 

    public double TotalInsertedCoins = 0;

     } 


    } 

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

public class CokeForm : Form

    public CokeForm()

public class Test 
{ 

    public static void Main() 
    {     

     CokeForm ColaForm; 
     ColaForm = new CokeForm(); 
     Application.Run(ColaForm); 
    } 
} 
} 

이제 매번 코인 버튼을 누르면, 내가 원하는이 부분에 수 다시 실행 :

int tester = 0; 
     if(Machine.TotalInsertedCoins == 0.05){tester = 1;} 
     if(Machine.TotalInsertedCoins > 0.05){tester = 2;} 
     else{tester = 0;} 


     switch(tester) 
     { 
      case 1: 
       TextBox1.Text = "Inserted Coins: €" + Machine.TotalInsertedCoins; 
       break; 
      case 2: 
       TextBox1.Text = "Inserted Coins: €" + Machine.TotalInsertedCoins + "0"; 
       break; 
      default: 
       TextBox1.Text = "Buy Your Ice Cold Drinks Here!"; 
       break; 
     } 

이 방법 콜라의 표시 기계는 당신이 삽입 한 돈의 금액을 말할 것입니다.

미리 감사드립니다.

Answer 1

리팩토링 밖으로 당신이 필요로하는 부분은 cokeform 생성자 내부 cokeform 생성자

public partial class CokeForm : Form 
{ 
    CokeMachine Machine = new CokeMachine(); 
    TextBox TextBox1; 

    public CokeForm() 
    { 
     ... 
    } 

에서 공공 방법

public void CoinInserted(object sender, EventArgs e) 
{ 
    int tester = 0; 
    if (Machine.TotalInsertedCoins == 0.05) { tester = 1; } 
    if (Machine.TotalInsertedCoins > 0.05) { tester = 2; } 

    switch (tester) 
    { 
     case 1: 
      TextBox1.Text = "Inserted Coins: €" + Machine.TotalInsertedCoins; 
      break; 
     case 2: 
      TextBox1.Text = "Inserted Coins: €" + Machine.TotalInsertedCoins + "0"; 
      break; 
     default: 
      TextBox1.Text = "Buy Your Ice Cold Drinks Here!"; 
      break; 
    } 
} 

이동 cokemachine 및 TextBox1에로 다시 실행, 다음 코드를 추가

Machine.Coin1.Click += new EventHandler(CoinInserted); 
Machine.Coin2.Click += new EventHandler(CoinInserted); 
Machine.Coin3.Click += new EventHandler(CoinInserted); 
Machine.Coin4.Click += new EventHandler(CoinInserted); 
Machine.Coin5.Click += new EventHandler(CoinInserted); 
Machine.Coin6.Click += new EventHandler(CoinInserted); 

CoinInserted(this, null);

그런 다음 코드 조각을 별도의 메서드에 넣고 필요한 위치로 호출해야합니다.
