Question

我正在尝试绑定到静态类，似乎无法让它正常工作。以下是我对XAML的看法：

<Window.Resources>
    <Game:ActivePlayers x:Key="ActivePlayerInfo" />
</Window.Resources>

<TextBlock x:Name="p1_Name" TextWrapping="Wrap" 
                           Text="{Binding Source={StaticResource ActivePlayerInfo}, Path=PlayerInfo.Player1.Name}" 
                           TextAlignment="Center" FontFamily="Showcard Gothic" VerticalAlignment="Top"  />

我可以访问ActivePlayerInfo类，因为如果我将Path更改为等于“Name”（我创建的临时依赖项属性），它就可以工作。以下是ActivePlayerInfo类的代码：

   public class ActivePlayers : DependencyObject
{
    public GameInfo PlayerInfo { get { return GameInfo.Singleton; } }


    public string Name
    {
        get { return (string)GetValue(NameProperty); }
        set { SetValue(NameProperty, value); }
    }

    // Using a DependencyProperty as the backing store for Name.  This enables animation, styling, binding, etc...
    public static readonly DependencyProperty NameProperty =
        DependencyProperty.Register("Name", typeof(string), typeof(ActivePlayers), new UIPropertyMetadata(""));

    public ActivePlayers()
    {
        Name = PlayerInfo.Player1.Name;

    }

}

GameInfo.Singleton：

       public class GameInfo
    {
        private static GameInfo gameDetails = new GameInfo();
        public static GameInfo Singleton
        {
            get { return gameDetails; }

        }
    public PlayerDetails Player1 = new PlayerDetails();

最后，PlayerDetails包含：

    public string Name
    {
        get { return (string)GetValue(NameProperty); }
        set { SetValue(NameProperty, value); }
    }

    public static readonly DependencyProperty NameProperty =
        DependencyProperty.Register("Name", typeof(string), typeof(PlayerDetails), new UIPropertyMetadata("New Player"));

将您的Player1字段更改为属性。

将Textblock绑定到静态类
