Unity：Dependency Injection

Question

public partial class HTCmds：ResourceDictionary { private ICanvasService mCanvasService;

 [Dependency] 
     public ICanvasService CanvasService 
     { 
      get { return mCanvasService; } 
      set { mCanvasService = value; } 
     } 

     public HTCmds() 
     { 
      CopyCommand = new DelegateCommand<object>(this.Copy, this.CanCopy); 
      ExitCommand = new DelegateCommand<object>(this.Exit); 
     } 

     public DelegateCommand<object> CopyCommand { get; private set; } 
     public DelegateCommand<object> ExitCommand { get; private set; } 
} 

資源詞典XAML中：

<ResourceDictionary x:Class="HTCmds" 
        x:ClassModifier="public" 
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
        xmlns:commands="clr-namespace:Commands;assembly=UIInfrastructure" 
        xmlns:r="clr-namespace:Microsoft.Windows.Controls.Ribbon;assembly=RibbonControlsLibrary" 
        xmlns:local="clr-namespace:Commands.Commands"> 
    <local:HTCmds x:Key="thisobj"/> 
    <commands:CommandReference x:Key="CopyCommandReference" Command="{Binding Source={StaticResource thisobj}, Path=CopyCommand}"/> 
    <commands:CommandReference x:Key="ExitCommandReference" Command="{Binding Source={StaticResource thisobj}, Path=ExitCommand}"/> 
</ResourceDictionary> 

我已經註冊了ICanvasService，但它不是在這個類中得到注入。資源詞典合併在Windows類的xaml文件中：

<ResourceDictionary> 
    <ResourceDictionary.MergedDictionaries> 
     <ResourceDictionary Source="../Commands/HTCmds.xaml" /> 
    </ResourceDictionary.MergedDictionaries> 
</ResourceDictionary> 

ResourceDictionary類是否有特定的內容？

謝謝& Regards， Vishal。

你HTCmds目標是通過WPF創建該行XAML的：

<local:HTCmds x:Key="thisobj"/> 

WPF還沒有統一的認識，因此不知道如何解決使用Unity的依賴關係。您需要使用UnityContainer.Resolve來解析對象。你不能依賴WPF爲你做這件事。
