WPF MVVM - 将UserControls上的属性绑定到容器的ViewModel

// UserControl的代码隐藏文件
public partial class MyUserControl : UserControl
{
    public static readonly DependencyProperty MyPropertyProperty = DependencyProperty.Register("MyProperty", typeof(string), typeof(MyUserControl));

    public MyUserControl()
    {
        InitializeComponent();
        BindingOperations.SetBinding(this, MyPropertyProperty, new Binding("MyViewModelProperty"));
    }

    public string MyProperty
    {
        get { return (string)GetValue(MyPropertyProperty); }
        set { SetValue(MyPropertyProperty, value); }
    }
}

// 容器的ViewModel
public class MyViewModel : INotifyPropertyChanged
{
    private string _myViewModelProperty;
    public string MyViewModelProperty
    {
        get { return _myViewModelProperty; }
        set
        {
            _myViewModelProperty = value;
            OnPropertyChanged("MyViewModelProperty");
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;

    protected virtual void OnPropertyChanged(string propertyName)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }
}

// 容器的XAML文件<Window ...
    DataContext="{StaticResource MyViewModel}">
   <StackPanel>
       <local:MyUserControl MyProperty="{Binding MyViewModelProperty}" />
    </StackPanel>
</Window>
