绑定Xaml WPF中的静态属性

问题描述：

亲爱的所有人，

我有一个类（Session），它包含静态属性。静态属性包含Brush类型属性（ForeGround）。我想在wpf xaml中的资源中绑定Foreground属性。

（Foreground ={Binding Source = {StaticResource session}，Path = Object.ForeGround} ）不起作用

我无法绑定Foreground属性。请帮助

以下是示例代码

Dear All,
I have a class (Session), which contain static property. Static property contain Brush type property (ForeGround). I want to bind Foreground property in a resource in wpf xaml.
(Foreground="{Binding Source={StaticResource session}, Path=Object.ForeGround}") does not work

I am unable to bind Foreground property. Please Help
Below is sample code

 public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            Session.Object = new Info() { ForeGround = Brushes.White };
        } 

private void Window_Loaded_1(object sender, RoutedEventArgs e)
        {
            //If I quick watch item. i got session object, and required foreground value is Ok.
            
            var item = this.FindResource("session");
        }       
    }

   //*****************************************
    public class Session
    {
        public static Info Object
        {
            get;
            set;
        }
    }

    //**************************************
    public class Info
    {
        public Brush ForeGround
        {
            get;
            set;
        }
    }

这里是WPF XAML

and here is WPF XAML

<Window.Resources>
       <local:Session x:Key="session"/>
   </Window.Resources>
   <Grid removed="Gray">
       <Viewbox>
           <TextBlock Name="txt" Text="Hello Text" Foreground="{Binding Source={StaticResource session}, Path=Object.ForeGround}"/>
       </Viewbox>

   </Grid>

看看： http://*.com/questions/936304/binding-to-static-property [ ^ ]

我认为这是单向绑定吗？要绑定到静态，可以使用x：静态绑定表达式。

take a look at : http://*.com/questions/936304/binding-to-static-property[^]

I take it this is one way binding? To bind to statics you can use the x:Static binding expression.

这可能适用于您要实现的目标：
