Question

window1的代码，这个类创建window2并创建我想发送到windows2的事件

public partial class Window1 : Window
{   //my event
    public class modificoHojaEventArgs : EventArgs
    {
        public ClaseHoja miHoja;
    }

    public delegate void modificoHojaEventHandler(object sender, 
    modificoHojaEventArgs e);
    public event modificoHojaEventHandler ModificoHojaHandler;
    protected virtual void OnAceptoHoja(modificoHojaEventArgs e)
    {
        if (this.ModificoHojaHandler != null)
            this.ModificoHojaHandler(this, e);
    } 
     //constructor
     public Window1()
     {
      InitializeComponent();
     }
     //create window2 w2 and send argumentos to w2
      private void BotonModificar_Click(object sender, RoutedEventArgs e)
    {
        window2 w2 = new window2();
        w2.Owner = this;
        w2.ShowDialog();
        modificoHojaEventArgs argumentos = new modificoHojaEventArgs();
        argumentos.miHoja = data;
        OnAceptoHoja(argumentos);

    }

我希望接收参数的window2代码

 public partial class DatosDeLaHoja : Window
{
  public DatosDeLaHoja( )
    {

        Window1 winn = new Window1();

这是我的问题，我无法从此窗口2获取window1

        winn=(Window1)PresentationSource.FromVisual(this).RootVisual
        winn.ModificoHojaHandler += winn_modifico;

        InitializeComponent();
      }


//receive argumentos using e variable
    void winn_modifico(object sender, Window1.modificoHojaEventArgs e)
    {
        cHoja = e.miHoja;


    }

Answer 1

在Windows 2中

创建此

public Window window1 {get; set; }

然后在窗口1

private void BotonModificar_Click(object sender, RoutedEventArgs e)
    {
        window2 w2 = new window2();
w2.window1 = this;
        w2.Owner = this;
        w2.ShowDialog();
        modificoHojaEventArgs argumentos = new modificoHojaEventArgs();
        argumentos.miHoja = data;
        OnAceptoHoja(argumentos);

    }

Answer 2

我不确定你打算通过这样做实现什么，但是你只需要将参数传递给 DatosDeLaHoja（）该参数显然应该是 window1 对象

如何从窗口（window1）向其拥有的窗口（window2）发送一个类
