NeutralResourcesLanguageAttribute Class

Informs the ResourceManager of the neutral culture of an assembly. This class cannot be inherited.

Namespace:  System.Resources
Assembly:  mscorlib (in mscorlib.dll)
Visual Basic (Declaration)
<ComVisibleAttribute(True)> _
<AttributeUsageAttribute(AttributeTargets.Assembly, AllowMultiple := False)> _
Public NotInheritable Class NeutralResourcesLanguageAttribute _
    Inherits Attribute
Visual Basic (Usage)
Dim instance As NeutralResourcesLanguageAttribute
C#
[ComVisibleAttribute(true)]
[AttributeUsageAttribute(AttributeTargets.Assembly, AllowMultiple = false)]
public sealed class NeutralResourcesLanguageAttribute : Attribute
Visual C++
[ComVisibleAttribute(true)]
[AttributeUsageAttribute(AttributeTargets::Assembly, AllowMultiple = false)]
public ref class NeutralResourcesLanguageAttribute sealed : public Attribute
JScript
public final class NeutralResourcesLanguageAttribute extends Attribute

The NeutralResourcesLanguageAttribute informs the ResourceManager of the language used to write the neutral culture's resources for an assembly, and can also inform the ResourceManager of the assembly to use (either the main assembly or a satellite assembly) to retrieve neutral resources using the resource fallback process. When looking up resources in the same culture as the neutral resources language, the ResourceManager automatically uses the resources located in the main assembly, instead of searching for a satellite assembly with the current user interface culture for the current thread. This will improve lookup performance for the first resource you load, and can reduce your working set.

NoteNote:

Apply this attribute to your main assembly, passing it the name of the neutral language that will work with your main assembly. Optionally, you can pass a member of the UltimateResourceFallbackLocation enumeration to indicate the location from which to retrieve fallback resources. Using this attribute is strongly recommended.

The following example demonstrates the use of the NeutralResourcesLanguageAttribute class.
