DependencyObject.Equals(Object) 方法

定义

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

public:
 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

参数

obj
Object

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

返回

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

注解

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.

继承者说明

DependencyObject 会替代两个基本 Object 方法: Equals(Object) 和 @no__t。 DependencyObject overrides and then seals two basic Object methods: Equals(Object) and GetHashCode(). 重写调用 Object 实现,导致对象相等性行为。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定义 @no__t 的值相等性。The purpose of these deliberate overrides is to prevent derived classes from trying to define a value equality for a DependencyObject. @No__t-0 的值 equalities 将永远不准确,因为 @no__t 的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. 这包括基本 [!INCLUDE[TLA2#tla_winclient](~/includes/tla2sharptla-winclient-md.md)] 功能,如数据绑定和 @no__t 属性系统。This includes fundamental [!INCLUDE[TLA2#tla_winclient](~/includes/tla2sharptla-winclient-md.md)] features such as data binding and the [!INCLUDE[TLA2#tla_winclient](~/includes/tla2sharptla-winclient-md.md)] property system.
