DependencyObject.DependencyObjectType Property

Gets the DependencyObjectType that wraps the CLR type of this instance. 

Namespace:  System.Windows
Assembly:  WindowsBase (in WindowsBase.dll)

member DependencyObjectType : DependencyObjectType with get

Property Value

Type: System.Windows.DependencyObjectType
A DependencyObjectType that wraps the CLR type of this instance.

This property is useful if an object that is returned from a method has a return value type of DependencyObject and you want to perform property system specific operations on it depending on its type. For example it is more efficient to call GetMetadata(DependencyObjectType) using the DependencyObjectType rather than the CLR  type. DependencyObjectType facilitates faster lookup.

In the following pseudocode example, MySubClass anticipates that additional derived classes might change the default value of the MyCustom dependency property. The class implements a default constructor that can determine the actual derived class by taking advantage of polymorphism on the DependencyObjectType value whenever that constructor is used as a derived class instantiator.

public DOClass() : base()

{

__customPropertyCache = (CustomDP)

CustomDPProperty.GetMetadata(DependencyObjectType).DefaultValue;

}
