将Window.DataContext设置为代码隐藏中的声明属性？

Question

我想实现像下面这样（注意Window元素的DataContext属性）：

<Window x:Class="Window1" 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    DataContext="{Binding MyDataContext}"/> 

Class Window1 
    Public ReadOnly Property MyDataContext() As IEnumerable(Of String) 
     Get 
      Return New String() {"Item1", "Item2"} 
     End Get 
    End Property 
End Class 

Answer 1

<Window x:Class="Window1" 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    DataContext="{Binding MyDataContext, RelativeSource={RelativeSource Self}}"> 
    <Grid> 
     <ListBox ItemsSource="{Binding}"/> 
    </Grid> 
</Window> 

我想这可能是最好使用一个DependencyProperty，应该同步好。
