DependencyObject.Equals(Object) DependencyObject.Equals(Object) DependencyObject.Equals(Object) DependencyObject.Equals(Object) Method


确定提供的 DependencyObject 是否等效于当前 DependencyObjectDetermines whether a provided DependencyObject is equivalent to the current DependencyObject.

 override bool Equals(System::Object ^ obj);
public override sealed bool Equals (object obj);
override this.Equals : obj -> bool
Public Overrides NotOverridable Function Equals (obj As Object) As Boolean


Object Object Object Object

要与当前实例进行比较的 DependencyObjectThe DependencyObject to compare to the current instance.


如果两个实例相同,则为 true;否则为 falsetrue if the two instances are the same; otherwise, false.


此实现只是引用相等性, 不会尝试计算所包含属性的值相等性。This implementation is reference equality only, and does not attempt to evaluate value equality of the contained properties.


DependencyObject重写然后密封两种Object基本方法Equals(Object) : GetHashCode()和。 DependencyObject overrides and then seals two basic Object methods: Equals(Object) and GetHashCode(). 重写调用Object实现, 从而导致对象相等行为。The overrides call the Object implementations, resulting in an object equality behavior. 这些有意的替代的目的是防止派生类尝试为指定值相等性DependencyObjectThe purpose of these deliberate overrides is to prevent derived classes from trying to define a value equality for a DependencyObject. 的值 equalities DependencyObject将永远不准确DependencyObject , 这是因为原始属性值更改功能及其依赖属性。Value equalities for DependencyObject will never be accurate because of the innate property value-changing capabilities of a DependencyObject and its dependency properties. 这包括数据[!INCLUDE[TLA2#tla_winclient](~/includes/]绑定[!INCLUDE[TLA2#tla_winclient](~/includes/]和属性系统等基础功能。This includes fundamental [!INCLUDE[TLA2#tla_winclient](~/includes/] features such as data binding and the [!INCLUDE[TLA2#tla_winclient](~/includes/] property system.
