Windows Store App Globalization: Referencing string resources in background code

The reference string resource is mentioned above in two ways, namely in the XAML element and references a string resource in the resource file in the background code. In the first section, which describes how to Reference string resources in XAML elements, this section explains the relevant knowledge points for referencing string resources in background code.

Create a new project named "Strings "In the folder,"Strings "new folder named"ZH-CN "and"en -USSubfolder and add a resource file to the two subfolders in the zh-cn in the resource file under folder, enter Figure 18-1 The resources shown in en - us in the resource file under folder, enter Figure 18-2 The resources shown.

in mainpage.xaml Grid of files element to add a "Display info" button and two TextBlock text block, button to get the value of a resource and display it in one of the TextBlock in a text block, another block of text is used to display the hint message, as shown in the following code:

<button content=" display information " fontsize= "HorizontalAlignment = "Left" margin= "557,170,0,0" verticalalignment= "Top" height= "" "Width=" "click=" showmessage_ click "/>

<textblock horizontalalignment= "left" margin= "730,185,0,0" textwrapping= "Wrap" name= "showstring" Verticalalignment= "Top" height= "fontsize=" "Width="/>

<textblock horizontalalignment= "left" margin= "555,130,0,0" textwrapping= "Wrap" text= "Click"Display Information"button Display StringResources"fontsize=" verticalalignment= "Top" height= "width=" 327 "/>"

in the MainPage.xaml.cs file, add a click event handling method for the Show Information button Showmessage_click , click the button to display the referenced string resource value, as shown in the following code:

Using Windows.ApplicationModel.Resources;

private void Showmessage_click (object sender, RoutedEventArgs e)

{

    // resourceloader resourceloader

var resourceloader = new Resourceloader ();

    //throughGetStringmethod getsStringresourcethe value of the resource

showstring.text = resourceloader.getstring ("Stringresource");

}

in theShowmessage_clickmethod, create a newResourceloaderobject of the classResourceloader,Resourceloaderclass provides basic access to resource files, referenced libraries, or string resources in other packages,UseResourceloaderclass needs to reference a namespaceWindows.ApplicationModel.Resources.
