We've previously observed how fields and methods are defined in classes in the earlier subject matter. For our Tutorial class, we might have the following Attributes. Tutorial ID – This tends to be utilized to retail store a singular range which would represent the Tutorial.
However, only rely on them Should the class has overridden or overloaded them to deliver a more info custom made definition of what "equality" means for objects of that style. The class might also put into action the IEquatable interface or maybe the IEqualityComparer interface. Each interfaces provide solutions which can be used to take a look at value equality. When building your personal classes that override Equals, Be sure to follow the rules said in The best way to: Define Benefit Equality for a kind and Object.Equals(Item). Relevant Sections
