Class DependencyObjectType
Type cache for all DependencyObject derived types
public class DependencyObjectType- Inheritance

DependencyObjectType
Remarks
Every DependencyObject stores a reference to its DependencyObjectType. This is an object that represents a specific system (CLR) Type.
DTypes have 2 purposes:
- More performant type operations (especially for Expressions that rely heavily on type inspection)
- Forces static constructors of base types to always run first. This consistancy is necessary for components (such as Expressions) that rely on static construction order for correctness.
Properties
- BaseType
The DependencyObjectType of the base class
- Id
Zero-based unique identifier for constant-time array lookup operations
- Name
Returns the name of the represented system (CLR) type
- SystemType
The system (CLR) type that this DependencyObjectType represents
Methods
- FromSystemType(Type)
Retrieve a DependencyObjectType that represents a given system (CLR) type
- GetHashCode()
Serves as a hash function for a particular type, suitable for use in hashing algorithms and data structures like a hash table
- IsInstanceOfType(DependencyObject)
Determines whether the specifed object is an instance of the current DependencyObjectType
- IsSubclassOf(DependencyObjectType)
Determines whether the current DependencyObjectType derives from the specified DependencyObjectType
