Remarks

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.

Constructors

ThemeInfoAttribute(ResourceDictionaryLocation, ResourceDictionaryLocation)

Initializes a new instance of the ThemeInfoAttribute class and creates an attribute that defines theme dictionary locations for types in an assembly.

Properties

GenericDictionaryLocation	The location of generic, not theme specific, resources.
ThemeDictionaryLocation	The location of theme specific resources.
TypeId	When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute)

Methods

Equals(Object)	Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute)
GetHashCode()	Returns the hash code for this instance. (Inherited from Attribute)
GetType()	Gets the Type of the current instance. (Inherited from Object)
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)
Match(Object)	When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Returns a string that represents the current object. (Inherited from Object)
