Examples

The following example uses the NeutralResourcesLanguageAttribute attribute to indicate that English is the app's default culture and that its resources are stored in a satellite assembly. The example itself includes resources in .txt files for the English and French cultures, as described in the following table:

Culture Resource name/value File name
English Greet=Hello Greet.en.txt
French Greet=Bonjour Greet.fr.txt

The following source code builds an app that changes the current UI culture first to French (France) and then to Russian (Russia) and displays an appropriate culture-specific resource in both cases.

   public static void Main()
   {
      ResourceManager rm = new ResourceManager("GreetResources", typeof(Example).Assembly); 
      Thread.CurrentThread.CurrentUICulture = CultureInfo.CreateSpecificCulture("fr-FR");
      Console.WriteLine("The current UI culture is {0}", Thread.CurrentThread.CurrentUICulture.Name);
      Console.WriteLine(rm.GetString("Greet"));
      
      Thread.CurrentThread.CurrentUICulture = CultureInfo.CreateSpecificCulture("ru-RU");
      Console.WriteLine("The current UI culture is {0}", Thread.CurrentThread.CurrentUICulture.Name);
      Console.WriteLine(rm.GetString("Greet"));
   }

You can use the following batch file to build and execute the C# version of the example. If you're using Visual Basic, replace csc with vbc, and replace the .cs extension with .vb. When the example is executed, it displays a French language string but throws a MissingSatelliteAssemblyException exception when the current culture is Russian (Russia). This is because the satellite assembly en\HelloWorld.dll that contains the resources of the default culture does not exist.


vbc HelloWorld.vb  

md fr  
resgen Greet.fr.txt  
al /out:fr\HelloWorld.resources.dll /culture:fr /embed:GreetResources.fr.resources  

HelloWorld  

You can use the following batch file to build and execute the Visual Basic version of the example. If you're using C#, replace vbc with csc, and replace the .vb extension with .cs. When the example is executed, it displays a French language string when the current UI culture is French (France). When the current UI culture is Russia (Russian), it displays an English language string because Russian language resources do not exist, but the resource manager is able to load the resources of the default culture from the satellite assembly en\HelloWorld2.dll.


vbc HelloWorld.vb /out:HelloWorld2.exe  

md fr  
resgen GreetResources.fr.txt  
al /out:fr\HelloWorld2.resources.dll /culture:fr /embed:GreetResources.fr.resources  

md en  
resgen GreetResources.en.txt  
al /out:en\HelloWorld2.resources.dll /culture:en /embed:GreetResources.en.resources

Remarks

The default culture is the culture whose resources are loaded if the appropriate culture-specific resources cannot be found. By default, resources for the default culture are located in the main assembly, and a MissingManifestResourceException is thrown if the resource manager tries to retrieve but cannot find a resource for the default culture. However, the .NET Framework will load the resources for an app's default culture from a satellite assembly if the NeutralResourcesLanguageAttribute attribute specifies a value of UltimateResourceFallbackLocation.Satellite for the location parameter. When this is the case, the MissingSatelliteAssemblyException exception is thrown when the resource manager tries to retrieve a resource of the default culture and the satellite assembly for the culture specified in the NeutralResourcesLanguageAttribute attribute is missing. Note that the exception is thrown by a resource retrieval method such as ResourceManager.GetString or ResourceManager.GetObject, and not when the ResourceManager object is instantiated.

MissingSatelliteAssemblyException uses the HRESULT COR_E_MISSINGSATELLITEASSEMBLY, which has the value 0x80131536.

MissingSatelliteAssemblyException uses the default Equals implementation, which supports reference equality.

For a list of initial property values for an instance of the MissingSatelliteAssemblyException class, see the MissingSatelliteAssemblyException constructors.

Note

You should always use the NeutralResourcesLanguageAttribute attribute to define your app's default culture so that if a resource for a specific culture is unavailable, your application will display acceptable behavior.
