如何使用Caliburn.micro EventAggregator MVVM在ViewModels之间传递值

public class MyEvent : PropertyChangedBase
{
    private string _value;
    public string Value
    {
        get { return _value; }
        set
        {
            _value = value;
            NotifyOfPropertyChange(() => Value);
        }
    }
}

public class SenderViewModel : Screen
{
    private readonly IEventAggregator _eventAggregator;

    public SenderViewModel(IEventAggregator eventAggregator)
    {
        _eventAggregator = eventAggregator;
    }

    public void SendMessage()
    {
        var myEvent = new MyEvent { Value = "Hello World" };
        _eventAggregator.PublishOnUIThread(myEvent);
    }
}

public class ReceiverViewModel : Screen, IHandle<MyEvent>
{
    private readonly IEventAggregator _eventAggregator;

    public ReceiverViewModel(IEventAggregator eventAggregator)
    {
        _eventAggregator = eventAggregator;
        _eventAggregator.Subscribe(this);
    }

    public void Handle(MyEvent message)
    {
        // 处理传递的值
        string value = message.Value;
        // ...
    }
}

public partial class App : Application
{
    private readonly IEventAggregator _eventAggregator = new EventAggregator();

    protected override void OnStartup(StartupEventArgs e)
    {
        base.OnStartup(e);

        var container = new SimpleContainer();
        container.Singleton<IWindowManager, WindowManager>();
        container.Singleton<IEventAggregator>(_eventAggregator);
        // 注册其他需要的服务

        var bootstrapper = new Bootstrapper(container);
        bootstrapper.Initialize();
    }
}
