ComponentResourceKey Constructors

Definition

Namespace:

System.Windows

Assembly:

PresentationFramework.dll

Initializes a new instance of the ComponentResourceKey class.

Overloads

ComponentResourceKey()	Initializes a new instance of the ComponentResourceKey class.
ComponentResourceKey(Type, Object)	Initializes a new instance of the ComponentResourceKey class, specifying the Type that defines the key, and an object to use as an additional resource identifier.

ComponentResourceKey()

Initializes a new instance of the ComponentResourceKey class.

public:
 ComponentResourceKey();

public ComponentResourceKey ();

Public Sub New ()

Remarks

The parameterless constructor is not generally used, because a TypeInTargetAssembly value and ResourceId value are required for proper initialization. The parameterless constructor exists primarily to support ComponentResourceKey Markup Extension XAML usage in named parameter form.

ComponentResourceKey(Type, Object)

Initializes a new instance of the ComponentResourceKey class, specifying the Type that defines the key, and an object to use as an additional resource identifier.

public:
 ComponentResourceKey(Type ^ typeInTargetAssembly, System::Object ^ resourceId);

public ComponentResourceKey (Type typeInTargetAssembly, object resourceId);

new System.Windows.ComponentResourceKey : Type * obj -> System.Windows.ComponentResourceKey

Public Sub New (typeInTargetAssembly As Type, resourceId As Object)

Parameters

typeInTargetAssembly

Type

The type that defines the resource key.

resourceId

Object

A unique identifier to differentiate this ComponentResourceKey from others associated with the typeInTargetAssembly type.

Examples

The following example creates a ComponentResourceKey that is then exposed as a static key of a control class to provide a style customization entry point.

public static ComponentResourceKey ViewBoxStyleKey =
    new ComponentResourceKey(typeof(MyAssemblyResources), "part_ViewBox");

Public Shared ViewBoxStyleKey As New ComponentResourceKey(GetType(MyAssemblyResources), "part_ViewBox")

Remarks

This constructor exist for two scenarios, with the first scenario being the most important:

• Supports creating a ComponentResourceKey that is then exposed as a public static field on a custom control class. This simplifies a control's access to its own defined resources in the template through {x:Static} usages for template property values.

• Supports ComponentResourceKey Markup Extension XAML usage in positional parameter form, which is one technique available for third parties that reference a component resource.
