UltimateResourceFallbackLocation Enumeration

Specifies the assembly for the ResourceManager class to use to retrieve neutral resources by using the Packaging and Deploying Resources.

Namespace:  System.Resources
Assembly:  mscorlib (in mscorlib.dll)

public enum UltimateResourceFallbackLocation

Member nameDescription
MainAssemblyFallback resources are located in the main assembly.
SatelliteFallback resources are located in a satellite assembly in the location specified by the Location property.

Use the UltimateResourceFallbackLocation enumeration with the NeutralResourcesLanguageAttribute constructor to specify whether the ResourceManager class is to retrieve neutral fallback resources from the main application assembly (the default), or from a satellite assembly.

The following code example displays the neutral language, fallback location, and fallback culture for a resource manager that is created for the current user interface culture or a culture specified on the command line.

using System;
using System.Resources;
using System.Globalization;
using System.Threading;

[assembly: NeutralResourcesLanguageAttribute("de" , UltimateResourceFallbackLocation.Satellite)]

public class Demo
        public static void Main(string[] args) {
			// If a specific culture is passed in through the command line, use that -- otherwise
			// just use the current ui culture
			String strCulture = "";
			if (args.Length == 1) 
				strCulture = args[0];
		if (strCulture != "") 
			try {
				Thread.CurrentThread.CurrentUICulture = new CultureInfo(strCulture);
			catch (ArgumentException e){
				Console.WriteLine(e.Message, "Bad command-line argument");
			Console.WriteLine("Current culture is: {0}", CultureInfo.CurrentUICulture.ToString());

		ResourceManager rm;

			rm = new ResourceManager("MyStrings", typeof(Demo).Assembly);
			NeutralResourcesLanguageAttribute attr = new NeutralResourcesLanguageAttribute("de", UltimateResourceFallbackLocation.Satellite);
			Console.WriteLine("Neutral language = " + rm.GetString("Language") + ", Fallback location = " + attr.Location.ToString() + ", Fallback culture = " + attr.CultureName.ToString());

		catch (MissingSatelliteAssemblyException e){
			Console.WriteLine(e.Message, "Unable to locate satellite Assembly");
