WPF 绑定五(本身就是数据源)

xaml：

<Window x:Class="WpfApplication1.Window5"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:String="clr-namespace:System;assembly=mscorlib"
        Title="Window5" Height="331" Width="538">
    <StackPanel Height="184" Name="stackPanel1" Width="288">
        <StackPanel.Resources>
            <String:String x:Key="myString">
                Hello,Good Afternoon!
            </String:String>
            
        </StackPanel.Resources>
        <TextBlock Height="23" Name="textBlock1" Text="{Binding Path=.,Source={StaticResource ResourceKey=myString}}" />
    </StackPanel>
</Window>
