如何从Form2的class2到form1的class1获得布尔值？

我尝试调用变量，但这没有成功。还是我做错了事

Class Form3UpgradesGunSounds

    // If you double click, it will select the sounds
    private void Form3UpgradesGunSounds_MouseDoubleClick(object sender, MouseEventArgs e)
    {
        if (e.X > 36 && e.X < 336 && e.Y > 35 && e.Y < 93) // FireTankCannon100
        {
            _tankCannon100 = true;
        }
        else if (e.X > 336 && e.X < 670 && e.Y > 35 && e.Y < 93) // FireTankCannon120
        {
            _tankCannon120 = true;
        }
        this.Close();
    }
    public bool GetTankCannon100()
    {
        return _tankCannon100;
    }
    public bool GetTankCannon120()
    {
        return _tankCannon120;
    }

类 Form1Game ：

    public void MoleShooter_MouseClick(object sender, MouseEventArgs e)
    {
        // ...  
        Form3UpgradesGunSounds fr3UpgradesSounds = new Form3UpgradesGunSounds();
        bool _f1tankCannon100 = fr3UpgradesSounds.GetTankCannon100();
        bool _f1tankCannon120 = fr3UpgradesSounds.GetTankCannon120();

        if (_f1tankCannon100 == false)
        {
            F1TankCannon100();
        }
        else if (_f1tankCannon120 == true)
        {
            F1TankCannon120();
        }
        // ... 
    }

    public void F1TankCannon100() { /*. Do something .*/ }

    public void F1TankCannon120() { /*. Do something .*/ }

我的问题是 如何从Form3UpgradesGunSounds

格式创建和访问Form1Game中的属性

Answer 1

1-像这样在Form2中创建一个新属性

  public partial class Form2: Form
    {
        public static bool BolleanProperty { get; set; }
        // ...
    }

2- static constructor集属性BolleanProperty = true

中

public partial class Form2: Form
{
    public static bool BolleanProperty { get; set; }
    static Form2()
    {
        BolleanProperty = true;

    }
    public Form2()
    {
        InitializeComponent();
    }
}

3-现在在Form1中，您可以在Form2中访问属性

 private void Form1_Load(object sender, EventArgs e)
        {
            label1.Text = Form2.BolleanProperty.ToString();
        }

更新了我对新贡献者Luuk Scherjon 的回答

要执行此操作，请按照以下步骤操作

在Form3UpgradesGunSounds中创建丝束public properties。

public bool TankCannon100 { get; set; }
public bool TankCannon120 { get; set; }

在Form3UpgradesGunSounds_MouseDoubleClick事件中

用属性替换_tankCannon100和_tankCannon120

if (...) // FireTankCannon100
  TankCannon100 = true;
else if (...) // FireTankCannon120
  TankCannon120 = true;

现在在Form1Game> MoleShooter_MouseClick中，您可以访问在Form3UpgradesGunSounds中创建的属性

public void MoleShooter_MouseClick(object sender, MouseEventArgs e)
    {
        // ...  
        Form3UpgradesGunSounds fr3UpgradesSounds = new Form3UpgradesGunSounds();

        if (!fr3UpgradesSounds.TankCannon100)
        {
            // do something 
        }
        if (fr3UpgradesSounds.TankCannon120)
        {
            // do something 
        }

        // ... 
    }
