Изображения в панели стека не отображаются

Question

У меня проблема, моя программа работает, но изображения не отображаются, я совершенно новый для C#, и я работал над этим единственным приложением навсегда! Я включил свой ПОЛНЫЙ код, в надежде, что кто-то мне поможет, главная проблема заключается в двух последних методах, я думаю. Предполагается, что это игра типа Whack a Mole.

Спасибо!

Answer 1

Ok. Удалите весь свой код и начните все заново.

По умолчанию подход к WPF (независимо от типа приложения, игра в этом случае) - это то, что называется MVVM, которое я расскажу вам, прежде чем вы напишете одну строку кода или XAML в WPF.

Это мой взгляд на то, что вы описали:

<Window x:Class="MiscSamples.WhackAMole" 
     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
     Title="WhackAMole" Height="300" Width="300"> 
    <ItemsControl ItemsSource="{Binding Moles}"> 
     <ItemsControl.ItemsPanel> 
      <ItemsPanelTemplate> 
       <UniformGrid Rows="3" Columns="3" IsItemsHost="True"/> 
      </ItemsPanelTemplate> 
     </ItemsControl.ItemsPanel> 
     <ItemsControl.ItemTemplate> 
      <DataTemplate> 
       <Image x:Name="Mole" Height="0" Width="100" 
         Source="/Images/Mole.Png" 
         Stretch="Fill" 
         VerticalAlignment="Bottom"/> 
       <DataTemplate.Triggers> 
        <DataTrigger Binding="{Binding IsUp}" Value="True"> 
         <DataTrigger.EnterActions> 
          <BeginStoryboard> 
           <Storyboard TargetName="Mole"> 
            <DoubleAnimation Storyboard.TargetProperty="Height" 
                From="0" To="77" 
                Duration="00:00:00.3"/> 
           </Storyboard> 
          </BeginStoryboard> 
         </DataTrigger.EnterActions> 
         <DataTrigger.ExitActions> 
          <BeginStoryboard> 
           <Storyboard TargetName="Mole"> 
            <DoubleAnimation Storyboard.TargetProperty="Height" 
                From="77" To="0" 
                Duration="00:00:00.3"/> 
           </Storyboard> 
          </BeginStoryboard> 
         </DataTrigger.ExitActions> 
        </DataTrigger> 
       </DataTemplate.Triggers> 
      </DataTemplate> 
     </ItemsControl.ItemTemplate> 
    </ItemsControl> 
</Window> 

Код За:

public partial class WhackAMole : Window 
{ 
    public WhackAMole() 
    { 
     InitializeComponent(); 

     DataContext = new WhackAMoleViewModel(); 
    } 
} 

ViewModel:

public class WhackAMoleViewModel: PropertyChangedBase 
{ 
    private List<Mole> _moles; 
    public List<Mole> Moles 
    { 
     get { return _moles; } 
    } 

    private System.Threading.Timer timer; 
    private System.Random random = new Random(); 

    public WhackAMoleViewModel() 
    { 
     _moles = Enumerable.Range(1, 9).Select(x => new Mole()).ToList(); 
     timer = new Timer(x => RaiseRandomMole(), null, 0, 300); 
    } 

    private void RaiseRandomMole() 
    { 
     //If random number is less than 5 skip this iteration 
     if (random.Next(1, 10) > 5) 
      return; 

     //Choose a random mole 
     var mole = Moles[random.Next(0, 8)]; 

     //If it's already raised, do nothing 
     if (mole.IsUp) 
      return; 

     //Raise it 
     mole.IsUp = true; 

     //Then Get it down somewhere between 1 and 2 seconds after 
     Task.Factory.StartNew(() => Thread.Sleep(random.Next(1000, 2000))) 
        .ContinueWith(x => mole.IsUp = false); 
    } 
} 

Data Item:

public class Mole: PropertyChangedBase 
{ 
    private bool _isUp; 
    public bool IsUp 
    { 
     get { return _isUp; } 
     set 
     { 
      _isUp = value; 
      OnPropertyChanged("IsUp"); 
     } 
    } 
} 

PropertyChangedBase класс (MVVM помощник):

public class PropertyChangedBase:INotifyPropertyChanged 
{ 
    public event PropertyChangedEventHandler PropertyChanged; 

    protected virtual void OnPropertyChanged(string propertyName) 
    { 
     Application.Current.Dispatcher.BeginInvoke((Action) (() => 
                   { 
                    PropertyChangedEventHandler handler = PropertyChanged; 
                    if (handler != null) handler(this, new PropertyChangedEventArgs(propertyName)); 
                   })); 
    } 
} 

Результат:

• Обратите внимание, что я использую WPF в анимации capabitilites, чтобы показать/скрыть родинки.
• Также обратите внимание, что в моем примере нет ни одной строки кода, которая ссылалась бы или манипулировала бы любыми элементами пользовательского интерфейса. Пользовательский интерфейс выполнен в XAML и реагирует на изменения в модели/ViewModel через DataBinding
• Я сделал базовый пример: он не поддерживает щелчок на родинок, для этого вам нужно будет использовать DelegateCommand.
• Постройте мой пример и следуйте моей логике (это правильный вариант). Не используйте элементы интерфейса в коде.
