如何使用XAML样式模板绑定到另一个对象属性？

<Style x:Key="MyButtonStyle" TargetType="Button">
    <Setter Property="Background" Value="Blue"/>
    <Setter Property="Foreground" Value="White"/>
</Style>

<Button Style="{StaticResource MyButtonStyle}" Content="Click me!"/>

<Style x:Key="MyButtonStyle" TargetType="Button">
    <Setter Property="Background" Value="{Binding ButtonBackground}"/>
    <Setter Property="Foreground" Value="White"/>
</Style>

public class ViewModel : INotifyPropertyChanged
{
    private Brush _buttonBackground;
    public Brush ButtonBackground
    {
        get { return _buttonBackground; }
        set
        {
            _buttonBackground = value;
            OnPropertyChanged(nameof(ButtonBackground));
        }
    }

    // INotifyPropertyChanged implementation...
}

<Window x:Class="MyApp.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="clr-namespace:MyApp"
        Title="My App" Height="450" Width="800">
    <Window.DataContext>
        <local:ViewModel/>
    </Window.DataContext>
    
    <Window.Resources>
        <Style x:Key="MyButtonStyle" TargetType="Button">
            <Setter Property="Background" Value="{Binding ButtonBackground}"/>
            <Setter Property="Foreground" Value="White"/>
        </Style>
    </Window.Resources>
    
    <Grid>
        <Button Style="{StaticResource MyButtonStyle}" Content="Click me!"/>
    </Grid>
</Window>
