1.封裝基類ComponentBase.cs 繼承自UserControl，定義組件中使用的屬性和命令

public class ComponentBase : UserControl
{
    private bool _isSelected;

    public bool IsSelected
    {
        get { return _isSelected; }
        set
        {
            _isSelected = value;

            if (value)
            {
                var parent = VisualTreeHelper.GetParent(this) as Grid;
                if (parent != null)
                {
                    foreach (var item in parent.Children)
                    {
                        if (item is ComponentBase)
                            (item as ComponentBase).IsSelected = false;
                    }
                }
            }
            VisualStateManager.GoToState(this, value ? "Selected" : "Unselected", false);
        }
    }

    public bool IsRunning
    {
        get { return (bool)GetValue(IsRunningProperty); }
        set { SetValue(IsRunningProperty, value); }
    }
    public static readonly DependencyProperty IsRunningProperty =
        DependencyProperty.Register("IsRunning", typeof(bool), typeof(ComponentBase), new PropertyMetadata(default(bool), new PropertyChangedCallback(OnRunningChanged)));

    private static void OnRunningChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        VisualStateManager.GoToState(d as ComponentBase, (bool)e.NewValue ? "RunState" : "Stop", false);
    }

    public bool IsFaultState
    {
        get { return (bool)GetValue(IsFaultStateProperty); }
        set { SetValue(IsFaultStateProperty, value); }
    }
    public static readonly DependencyProperty IsFaultStateProperty =
        DependencyProperty.Register("IsFaultState", typeof(bool), typeof(ComponentBase), new PropertyMetadata(default(bool), new PropertyChangedCallback(OnFaultStateChanged)));

    private static void OnFaultStateChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        VisualStateManager.GoToState(d as ComponentBase, (bool)e.NewValue ? "FaultState" : "NormalState", false);
    }

    public ICommand Command
    {
        get { return (ICommand)GetValue(CommandProperty); }
        set { SetValue(CommandProperty, value); }
    }
    public static readonly DependencyProperty CommandProperty =
        DependencyProperty.Register("Command", typeof(ICommand), typeof(ComponentBase), new PropertyMetadata(default(ICommand)));

    public object CommandParameter
    {
        get { return (object)GetValue(CommandParameterProperty); }
        set { SetValue(CommandParameterProperty, value); }
    }
    public static readonly DependencyProperty CommandParameterProperty =
        DependencyProperty.Register("CommandParameter", typeof(object), typeof(ComponentBase), new PropertyMetadata(default(object)));

    public ComponentBase()
    {
        this.PreviewMouseLeftButtonDown += ComponentBase_PreviewMouseLeftButtonDown;
    }

    private void ComponentBase_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
    {
        this.IsSelected = !this.IsSelected;

        this.Command?.Execute(this.CommandParameter);

        e.Handled = true;
    }
}

2.編寫設計冷卻塔組件CoolingTower.xaml，使用<local:ComponentBase>節(jié)點包裹，綁定基礎組件類中的上下文

后臺代碼繼承ComponentBase基類
