Windows商店应用程序ResourceLoader在设计时 [英] Windows store app ResourceLoader at design time

问题描述

我已经开始为Windows 8.1创建Windows Store应用程序，现在遇到了与本地化有关的问题。

我想从显示一个字符串资源。在设计时使用resw文件，但是每次尝试都失败了，即使它在运行时也有效。

使用x：Uid属性时，我仍然必须提供Text属性（即TextBlock的属性），并且我不想重复写两次文本。

我还尝试在viewmodel上为字符串创建一个属性：

 公共字符串标题
 {
 get {return ResourceLoader.GetForCurrentView（ Strings）。GetString（ MainView_Title）; } 
} 
  

此功能在运行时有效，但在设计时为空白。 / p>

所以问题是，有没有办法在XAML设计器中显示.resw文件中的资源？

更具体地说，ResourceManager类是否允许在设计时读取.resw文件？

感谢您的帮助，
Lucas

解决方案

旧方法

因此，您可以做几件事。

第一个（也是最简单的，因为您已经在使用 x：Uid ）是仅提供文本进入文本字段。与 x：Uid 相关的值将覆盖其中的所有内容。

 < TextBlock Text = MyText x：Uid = MainView_Title /> 
  

第二种方法是使用已经拥有的属性，然后检查应用程序是否处于设计时间（通过几种不同的方法），如果是则返回一个常数，如果不是，则返回一个资源。

  public string Title 
 {
 if（ViewModelBase.IsInDesignTimeStatic）// Mvvm Light的简单访问器
返回我的文本； 
返回ResourceLoader.GetForCurrentView（ Strings）。GetString（ MainView_Title）; 
} 
  

希望这会帮助您并且编码愉快！

编辑：至少从Windows 8.1开始，似乎有一种新的方法。

新方法

• 创建一个引用 ResourceLoader 的类（类似于上述属性）。



• 创建一个索引属性访问器，该访问器接受字符串键并从 ResourceLoader 返回值。

   公共类LocalizedStrings 
   {
   public string this [string key] 
   {
   get 
   {
  返回App.ResourceLoader.GetForViewIndependentUse（）。GetString（key）; 
  } 
  } 
  } 
    




• 在您的 App.xaml ，定义此类型的 StaticResource 。

   < Application.Resources> 
  < ResourceDictionary> 
  < common：LocalizedStrings x：Key = Localized /> 
  < / ResourceDictionary> 
  < /Application.Resources> 
    

现在，当您要访问物业时输入键 MainView_Title 使用此功能。它比较冗长，但应同时在设计器和应用程序本身中进行翻译。

 < TextBlock Text = {Binding Source = {StaticResource Localized}，Path = [MainView_Title]} /> 
  

如果需要，您可以对其进行改编以提高可读性，例如：

 < TextBlock Text = {Binding [MainView_Title]，Source = {StaticResource Localized}} /> 
  

I've started creating a Windows Store App for Windows 8.1 and now I encountered a problem concerning localization.

I would like to display a string resource from a .resw file at design time, but every attempt to do so has failed, even though it works at runtime.

When using the x:Uid attribute, I still have to supply the Text property (i.e. for a TextBlock) and I don't like to write the text twice.

I also tried creating a property for the string on the viewmodel:

public string Title
{
    get { return ResourceLoader.GetForCurrentView("Strings").GetString("MainView_Title"); }
}

This is working at runtime, but at design time it is blank.

So the question is, is there a way to display resources from a .resw file in the XAML-designer?

More specifically, does the ResourceManager class allow .resw files to be read at design time?

Thanks for your help, Lucas

解决方案

Old Method

So, there are a couple of things you can do.

The first (and simplest, given that you're using x:Uid already) is to just supply the text into the Text field. The x:Uid-related value will overwrite whatever is in there.

<TextBlock Text="MyText" x:Uid="MainView_Title"/>

The second method is to use the property like you already have, and then check to see if the app is in Design Time (through a couple of different methods), then return a constant value if it is and the Resource if it is not.

public string Title
{
     if(ViewModelBase.IsInDesignTimeStatic) //Mvvm Light's easy accessor
         return "My Text";
     return ResourceLoader.GetForCurrentView("Strings").GetString("MainView_Title");
}

Hope this helps and happy coding!

Edit: There appears to be a new way to do this, at least as of Windows 8.1.

New Method

• Create a class which references a ResourceLoader (similar to the property described above).

• Create an indexed property accessor which accepts a string key and return the value from the ResourceLoader.

  public class LocalizedStrings
  {
      public string this[string key]
      {
          get
          {
              return App.ResourceLoader.GetForViewIndependentUse().GetString(key);
          }
      }
  }
  

• In your App.xaml, define a StaticResource of this type.

  <Application.Resources>
      <ResourceDictionary>
          <common:LocalizedStrings x:Key="Localized"/>
      </ResourceDictionary>
  </Application.Resources>
  

Now, when you want to access your property with entry key MainView_Title, use this. It's more verbose, but it should translate both in the designer and in the app itself.

<TextBlock Text="{Binding Source={StaticResource Localized}, Path=[MainView_Title]}" />

You can shuffle it around to be a bit more readable if you'd like, such as:

<TextBlock Text="{Binding [MainView_Title], Source={StaticResource Localized}}" />
