Gets the DependencyObjectType that wraps the CLR type of this instance.
public:
property System::Windows::DependencyObjectType ^ DependencyObjectType { System::Windows::DependencyObjectType ^ get(); };public System.Windows.DependencyObjectType DependencyObjectType { get; }member this.DependencyObjectType : System.Windows.DependencyObjectTypePublic ReadOnly Property DependencyObjectType As DependencyObjectTypeProperty Value
A DependencyObjectType that wraps the CLR type of this instance.
Examples
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 parameterless 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;
}
Remarks
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.
