Specifies the location in which theme dictionaries are stored for an assembly.

System.Object
  System.Attribute
    System.Windows.ThemeInfoAttribute

Namespace:  System.Windows
Assembly:  PresentationFramework (in PresentationFramework.dll)
[AttributeUsageAttribute(AttributeTargets.Assembly)]
public sealed class ThemeInfoAttribute : Attribute

The ThemeInfoAttribute type exposes the following members.

  Name Description
Public method ThemeInfoAttribute Initializes a new instance of the ThemeInfoAttribute class and creates an attribute that defines theme dictionary locations for types in an assembly.
Top
  Name Description
Public property GenericDictionaryLocation The location of generic, not theme specific, resources.
Public property ThemeDictionaryLocation The location of theme specific resources.
Public property TypeId When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)
Top
  Name Description
Public method Equals Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
Protected method Finalize Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public method GetHashCode Returns the hash code for this instance. (Inherited from Attribute.)
Public method GetType Gets the Type of the current instance. (Inherited from Object.)
Public method IsDefaultAttribute When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
Public method Match When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
Protected method MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Public method ToString Returns a string that represents the current object. (Inherited from Object.)
Top
  Name Description
Explicit interface implemetation Private method _Attribute.GetIDsOfNames Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
Explicit interface implemetation Private method _Attribute.GetTypeInfo Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
Explicit interface implemetation Private method _Attribute.GetTypeInfoCount Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
Explicit interface implemetation Private method _Attribute.Invoke Provides access to properties and methods exposed by an object. (Inherited from Attribute.)

This attribute is used at the assembly level to indicate which theme resource dictionaries are being declared by an assembly for its defined controls, and where the resource dictionaries are located.

For example, if you do not provide theme-specific resource dictionaries, and your generic.xaml that supplies resource definitions for all resource lookups is compiled into the same assembly in which the assembly's control class definitions exist, you would apply the following attribution in the AssemblyInfo.cs for the assembly project:

[assembly:ThemeInfoAttribute(ResourceDictionaryLocation.None, ResourceDictionaryLocation.SourceAssembly)]

In addition to ThemeInfoAttribute application, your project and assembly must have additional characteristics in order for the resource dictionaries to be usable by the WPF theming system.

  • If you declare SourceAssembly, then the referenced resource dictionary should be placed within a themes directory in the assembly structure.

  • If you declare SourceAssembly for ThemeDictionaryLocation, then the names of the XAML files are expected to conform to the XAML file naming scheme themes\<Theme Name>.<Theme Color>.xaml. For example, the following is a list of theme files that support a variety of possible WPF theming scenarios on clients:

    • themes\luna.normalcolor.xaml

    • themes\luna.homestead.xaml

    • themes\luna.metallic.xaml

    • themes\royale.normalcolor.xaml

    • themes\aero.normalcolor.xaml

    • themes\classic.xaml

  • If you declare ExternalAssembly, then the external assembly names are expected to conform to a naming scheme, and each assembly for each theme should be built using the same key information.

For more information about how to create and use theme resource dictionaries, see "Defining Resources at the Theme Level" section of the topic Control Authoring Overview.
