在运行时更新内容WPF

我希望能够在运行时显示一些属性更改，我不知道该怎么做。我正在学习绑定，下面的示例工作正常，但我希望能够在运行时监视绑定属性的更改。在运行时更新内容WPF

我有一类球员：

class Player : INotifyPropertyChanged 
{ 
    public event PropertyChangedEventHandler PropertyChanged; 

    private string id; 
    public string ID { get => id; } 

    private int power; 
    public int Power 
    { 
     get => power; 
     set 
     { 
      if (this.power != value) 
      { 
       this.power = value; 
       if (this.PropertyChanged != null) 
        this.NotifyPropertyChanged("Power"); 
      } 
     } 
    } 


    public Player(string playerId) 
    { 
     id = playerId; 
     power = 50; 
    } 
}

我创建的球员，谁自相残杀一些数字，赚取或失去权力。使用点的功率分布的数据绑定我显示所有玩家的ID和电源点在ListView和直方图，使用面：

public partial class MainWindow : Window, INotifyPropertyChanged 
    { 
     private static readonly Random random = new Random(); 

     public event PropertyChangedEventHandler PropertyChanged; 
     public void NotifyPropertyChanged(string propName) 
     { 
      if (this.PropertyChanged != null) 
       this.PropertyChanged(this, new PropertyChangedEventArgs(propName)); 
     } 

     private ObservableCollection<Player> players; 

     private PointCollection powerHistogramPoints; 
     public PointCollection PowerHistogramPoints 
     { 
      get => this.powerHistogramPoints; 
      set 
      { 
       if (this.powerHistogramPoints != value) 
       { 
        this.powerHistogramPoints = value; 
        if (this.PropertyChanged != null) this.NotifyPropertyChanged("PowerHistogramPoints"); 
       } 
      } 
     } 

     public MainWindow() 
     { 
      InitializeComponent(); 
      this.DataContext = this; 

      players = new ObservableCollection<Player> { }; 
      for (int i = 1; i < 10; i++) players.Add(new Player("player" + i.ToString("D3"))); 
      popListView.ItemsSource = players; 
      CreateHistogram(); 
     } 

     private void runButton_Click(object sender, RoutedEventArgs e) 
     { 
      RunEpochs(Int32.Parse(nEpochsTextBox.Text)); 
      CreateHistogram(); 
     } 

     private int[] CreateHistogram(...){...} 

     internal void RunEpochs(int nEpochs) 
     {for (int i = 0; i < nEpochs; i++) RunEpoch();} 
     private void RunEpoch(){...} 
    }

和XAML代码：

 <ListView Margin="2" Name="popListView"> 
      <ListView.View> 
       <GridView> 
        <GridViewColumn Header="player ID" Width="120" DisplayMemberBinding="{Binding ID}" /> 
        <GridViewColumn Header="power" Width="50" DisplayMemberBinding="{Binding Power}" /> 
       </GridView> 
      </ListView.View> 
     </ListView>

和

  <GroupBox Height="200" Width="300" Header="Power Distribution" BorderThickness="0"> 
       <Border BorderThickness="1" BorderBrush="Black" Background="White" Margin="4"> 
        <Polygon Points="{Binding PowerHistogramPoints}" Stretch="Fill" Fill="Black" Opacity="0.8" /> 
       </Border> 
      </GroupBox>

我有控制，允许我选择运行多少个时代，并且在他们运行后，列表视图和直方图都很好地更新。但我希望能够运行一百万个时代，并且能够实时监控玩家点和直方图的变化（例如，每1000个时代或每秒钟更新列表和图表等） ..）我应该做什么更改上面的代码？

任何帮助，将不胜感激！

你可以从你的属性二传手删除对NotifyPropertyChanged来电，

而且手动打电话给他们你的计时器击中了你设定的ElapsedTime后。

该计时器可以在后台工作线程中，并执行Dispatcher.BeginInvoke块内的所有通知。
