PopupWindowAction如何使用MetroWindow？

 

public class Window1ViewModel:BindableBase,IInteractionRequestAware
    {
        #region Properties
        private string str;

        public string Str
        {
            get { return str; }
            set { SetProperty(ref str, value); }
        }

        #endregion

        /// <summary>
        /// Cancel
        /// </summary>
        private DelegateCommand<Window> clickCommand;

        public DelegateCommand<Window> ClickCommand
        {
            get
            {
                if (clickCommand == null)
                    clickCommand = new DelegateCommand<Window>(Click);
                return clickCommand;
            }
        }

        private INotification  notification;

        public INotification Notification
        {
            get { return notification; }
            set { SetProperty(ref notification,value); }
        }

        public Action FinishInteraction { get; set; }

        private void Click(Window window)
        {
            var _notification = (Window1DialogModel)Notification;
            _notification.Str = this.str;
            _notification.Confirmed = true;
            FinishInteraction?.Invoke();
        }
    }

Window1ViewModel

  public class Window1DialogModel : IConfirmation
    {

        //Interface Content
        public bool Confirmed { get ; set ; }
        public string Title { get ; set ; }
        public object Content { get; set; }
