WPF将对象从窗口的Usercontrol传递到另一个窗口的Usercontrol

public class MyData : INotifyPropertyChanged
{
    private string _name;
    public string Name
    {
        get { return _name; }
        set
        {
            _name = value;
            OnPropertyChanged(nameof(Name));
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;

    protected virtual void OnPropertyChanged(string propertyName)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }
}

<UserControl x:Class="SenderUserControl"

    <!-- 其他控件和布局 -->

    <Button Content="发送" Click="SendButton_Click" />
</UserControl>

private void SendButton_Click(object sender, RoutedEventArgs e)
{
    // 获取要传递的数据
    string data = myData.Name;

    // 创建接收方窗口的实例
    ReceiverWindow receiverWindow = new ReceiverWindow();

    // 将数据传递给接收方窗口的UserControl
    receiverWindow.MyDataObject = myData;

    // 显示接收方窗口
    receiverWindow.Show();
}
