- obj
- Object
The DependencyObject to compare to the current instance.
Returns
true if the two instances are the same; otherwise, false.
Remarks
This implementation is reference equality only, and does not attempt to evaluate value equality of the contained properties.
Notes to Inheritors
DependencyObject overrides and then seals two basic Object methods: Equals(Object) and GetHashCode(). The overrides call the Object implementations, resulting in an object equality behavior. The purpose of these deliberate overrides is to prevent derived classes from trying to define a value equality for a DependencyObject. Value equalities for DependencyObject will never be accurate because of the innate property value-changing capabilities of a DependencyObject and its dependency properties. This includes fundamental WPF features such as data binding and the WPF property system.
