ResourceManager.GetString Method (String, CultureInfo)


Returns the value of the string resource localized for the specified culture.

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

public virtual string GetString(
	string name,
	CultureInfo culture


Type: System.String

The name of the resource to retrieve.

Type: System.Globalization.CultureInfo

An object that represents the culture for which the resource is localized.

Return Value

Type: System.String

The value of the resource localized for the specified culture, or null if name cannot be found in a resource set.

Exception Condition

The name parameter is null.


The value of the specified resource is not a string.


No usable set of resources has been found, and there are no resources for a default culture. For information about how to handle this exception, see the "Handling MissingManifestResourceException and MissingSatelliteAssemblyException Exceptions" section in the ResourceManager class topic.


The default culture's resources reside in a satellite assembly that could not be found. For information about how to handle this exception, see the "Handling MissingManifestResourceException and MissingSatelliteAssemblyException Exceptions" section in the ResourceManager class topic.

The GetString(String, CultureInfo) method is thread safe.

In desktop apps, if culture is null, the GetString(String, CultureInfo) method uses the current UI culture obtained from the CultureInfo.CurrentUICulture property.

The resource that is returned is localized for the culture specified by the culture parameter. If the resource has not been localized for culture, the resource manager probes for a resource by following the steps outlined in the "Resource Fallback Process" section of the Packaging and Deploying Resources in Desktop Apps topic. If no usable set of resources is found, the resource manager falls back on the default culture's resources. If the resource manager cannot load the default culture's resource set, the method throws a MissingManifestResourceException exception or, if the resource set is expected to reside in a satellite assembly, a MissingSatelliteAssemblyException exception. If the resource manager can load an appropriate resource set but cannot find a resource named name, the method returns null.

The IgnoreCase property determines whether the comparison of name with the names of resources is case-insensitive (the default) or case-sensitive.


This method can throw more exceptions than are listed. One reason this might occur is if a method that this method calls throws an exception. For example, a FileLoadException exception might be thrown if an error was made deploying or installing a satellite assembly, or a SerializationException exception might be thrown if a user-defined type throws a user-defined exception when the type is deserialized.


Although the ResourceManagerclass is supported in Windows 8.x Store apps, we do not recommend its use. Use this class only when you develop Portable Class Library projects that can be used with Windows 8.x Store apps. To retrieve resources from Windows 8.x Store apps, use the Windows.ApplicationModel.Resources.ResourceLoader class instead.

In Windows 8.x Store apps, the GetString(String, CultureInfo) method returns the value of the name string resource, localized for the culture specified by the culture parameter. If the resource is not localized for the culture culture, the lookup uses the entire Windows 8 language fallback list, and stops after looking in the default culture. If the resource manager cannot match name, the method returns null.

The following example uses the GetString(String, CultureInfo) method to retrieve culture-specific resources. The example's default culture is English (en), and it includes satellite assemblies for the French (France) (fr-FR) and Russian (Russia) (ru-RU) cultures. The example changes the current culture and current UI culture to Russian (Russia) before calling GetString(String, CultureInfo). It then calls the GetString method and the DateTime.ToString(String, IFormatProvider) method and passes CultureInfo objects that represent the French (France) and Swedish (Sweden) cultures to each method. In the output, the month and day of the month as well as the string that precedes them appear in French, because the GetString method is able to retrieve the French language resource. However, when the Swedish (Sweden) culture is used, the month and day of the month appear in Swedish, although the string that precedes them is in English. This is because the resource manager cannot find localized Swedish language resources, so it returns a resource for the default English culture instead.

The example requires the text-based resource files listed in following table. Each has a single string resource named DateStart.


File name

Resource name

Resource value




Today is



Aujourd'hui, c'est le




You can use the following batch file to compile the Visual Basic example. To compile in C#, change vbc to csc, and change the extension of the source code file from .vb to .cs.

resgen DateStrings.txt
vbc showdate.vb /resource:DateStrings.resources

md fr-FR
al /out:fr-FR\Showdate.resources.dll /culture:fr-FR / 

md ru-RU
al /out:ru-RU\Showdate.resources.dll /culture:ru-RU /

Here's the source code for the example (ShowDate.vb for the Visual Basic version or ShowDate.cs for the C# version).

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


public class Example
   public static void Main()
      Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture("ru-RU");
      Thread.CurrentThread.CurrentUICulture = CultureInfo.CreateSpecificCulture("ru-RU");

      string[] cultureNames = { "fr-FR", "sv-SE" };
      ResourceManager rm = new ResourceManager("DateStrings",

      foreach (var cultureName in cultureNames) {
         CultureInfo culture = CultureInfo.CreateSpecificCulture(cultureName);
         string dateString = rm.GetString("DateStart", culture);
         Console.WriteLine("{0}: {1} {2}.", culture.DisplayName, dateString, 
                                            DateTime.Now.ToString("M", culture));                           
// The example displays output similar to the following:
//       French (France): Aujourd'hui, c'est le 7 février.
//       Swedish (Sweden): Today is den 7 februari.
