如何在XAML里面 使用Resoures.resx 里面定义的值

<Window.Resources>
      <x:ArrayExtension x:Key="OpenBtn_Res" Type="{x:Type System:String}">
         <x:StaticExtension Member="prop:Resources.OpenToolName"/>
         <System:String>\Image\Table_Open.png</System:String>
     </x:ArrayExtension>
     <x:ArrayExtension x:Key="AddBtn_Res" Type="{x:Type System:String}">
         <x:StaticExtension Member="prop:Resources.AddToolName"/>
         <System:String>\Image\Data_add.png</System:String>
     </x:ArrayExtension>
     <x:ArrayExtension x:Key="EditBtn_Res" Type="{x:Type System:String}">
         <x:StaticExtension Member="prop:Resources.EditToolName"/>
         <System:String>\Image\Data_edit.png</System:String>
     </x:ArrayExtension>
     <x:ArrayExtension x:Key="DeleteBtn_Res" Type="{x:Type System:String}">
         <x:StaticExtension Member="prop:Resources.DelToolName"/>
         <System:String>\Image\Data_delete.png</System:String>
     </x:ArrayExtension>
</Window.Resources>

里面的汉字就是从资源文件中读出的 要利用staticextension
