在 C# 类之间传递数据

  • 772

传递数据时,我调用递归并用完堆栈,原因如下:

类有需要传递给类的Controller_MainForm变量public int cordX, cordY;Raket

这是我正在尝试做的事情:

class Raket
{
    Controller_MainForm control;

    public Raket() 
    {
        control = new Controller_MainForm();

        x = control.cordX;
        y = control.cordY;
    }

但是在类方法中创建Controller_MainForm了类的实例Model

 public partial class Controller_MainForm : Form
{
    View view;
    Model model;
    public int cordX, cordY;

    Thread modelGo;

    public Controller_MainForm() : this(850) { }
    public Controller_MainForm(int sizeField) : this(sizeField, 1) { }
    public Controller_MainForm(int sizeField, int amountRaket) : this(sizeField, amountRaket, 1) { }
    public Controller_MainForm(int sizeField, int amountRaket, int amountAero) : this(sizeField, amountRaket, amountAero, 40) { }
    public Controller_MainForm(int sizeField, int amountRaket, int amountAero, int speedGame)
    {
        InitializeComponent();

        model = new Model(sizeField, amountAero, amountRaket, speedGame);

        view = new View(model);
        this.Controls.Add(view);

        cordX = Convert.ToInt32(textBox1.Text);
        cordY = Convert.ToInt32(textBox2.Text);
    }

    private void Start_Click(object sender, EventArgs e)
    {
        if (model.gameStatus == GameStatus.stoping)
        {
           model.gameStatus = GameStatus.playing;
           modelGo = new Thread(model.Go);
           modelGo.Start();
           view.Invalidate();
        }  
    }

    private void Controller_MainForm_FormClosing(object sender, FormClosingEventArgs e)
    {
        if (modelGo != null)
        {
            model.gameStatus = GameStatus.stoping;
            modelGo.Abort();
        }

        DialogResult dr = MessageBox.Show("Закрыть приложение?" , "Radionavig_24", MessageBoxButtons.YesNoCancel);
        if (dr == DialogResult.Yes)
            e.Cancel = false;
        else
            e.Cancel = true;
    }
}

在模型类中,方法:

class Model
{
    int sizeField;
    int amountRaket;
    int amountAero;
    public int speedGame;

    public GameStatus gameStatus;

    public Raket raket;

    public Model(int sizeField, int amountRaket, int amountAero, int speedGame)
    {
        this.sizeField = sizeField;
        this.amountAero = amountAero;
        this.amountRaket = amountRaket;
        this.speedGame = speedGame;

        raket = new Raket();

        gameStatus = GameStatus.stoping;
    }

    public void Go()
    {
        while (gameStatus == GameStatus.playing)
        {
            Thread.Sleep(speedGame);
            raket.Run();
        }
    }
}

并再次创建一个实例,new Raket()如此循环。如何在不递归的情况下传递数据?Raket()Controller_MainForm

static class Program
{
    /// <summary>
    /// The main entry point for the application.
    /// </summary>
    [STAThread]
    static void Main(string[] arg)
    {
        Controller_MainForm cm;

        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);

        switch (arg.Length)
        {
            case 0: cm = new Controller_MainForm(); break;
            case 1: cm = new Controller_MainForm(Convert.ToInt32(arg[0])); break;
            case 2: cm = new Controller_MainForm(Convert.ToInt32(arg[0]), Convert.ToInt32(arg[1])); break;
            case 3: cm = new Controller_MainForm(Convert.ToInt32(arg[0]), Convert.ToInt32(arg[1]), Convert.ToInt32(arg[2])); break;
            case 4: cm = new Controller_MainForm(Convert.ToInt32(arg[0]), Convert.ToInt32(arg[1]), Convert.ToInt32(arg[2]), Convert.ToInt32(arg[3])); break;
            default: cm = new Controller_MainForm(); break;
        }

        Application.Run(cm);
    }
}

    我不太了解你的类的依赖关系和层次结构,但你可以像这样实现将对象传递给构造函数:

    火箭级:

    class Raket
    {
        Controller_MainForm control;
    
        public Raket(Controller_MainForm controller) 
        {
            this.control = controller;
    
            x = control.cordX;
            y = control.cordY;
        }
    

    Controller_MainForm 类:

    public Controller_MainForm() : this(850) { }
    public Controller_MainForm(int sizeField) : this(sizeField, 1) { }
    public Controller_MainForm(int sizeField, int amountRaket) : this(sizeField, amountRaket, 1) { }
    public Controller_MainForm(int sizeField, int amountRaket, int amountAero) : this(sizeField, amountRaket, amountAero, 40) { }
    public Controller_MainForm(int sizeField, int amountRaket, int amountAero, int speedGame)
    {
        InitializeComponent();
    
        model = new Model(sizeField, amountAero, amountRaket, speedGame, this);
    
        view = new View(model);
        this.Controls.Add(view);
    
        cordX = Convert.ToInt32(textBox1.Text);
        cordY = Convert.ToInt32(textBox2.Text);
    }
    

    模型类:

        public Model(int sizeField, int amountRaket, int amountAero, int speedGame, Controller_MainForm controller)
        {
            this.sizeField = sizeField;
            this.amountAero = amountAero;
            this.amountRaket = amountRaket;
            this.speedGame = speedGame;
    
            this.raket = new Raket(controller);
        }
    

    您的构造函数Controller_MainForm()与列表中显示的构造函数不匹配。因此,我几乎是随意写的。

    如果有什么不对,请写在评论中。
