The "No" in part 2 of the answer is actually incorrect. Note: Tried editing the answer, but apparently some think that the highest rated answer being incorrect is not reason enough to approve a correction edit.

g. MyType and Object) which will still use the identity comparison. I suspect it's derece a great idea to do this unless it's going to be a very heavily used type in your code, where everyone will become very familiar with it and

Equals and object.ReferenceEquals. Equals is meant to be overridden for whatever sort of comparison makes the most sense for a given type, whereas ReferenceEquals kişi't be overridden and always compares by reference.

Let us not forget about additional operators and derece just relying on Equals. We emanet implement the == and != operators easily:

The generic tuple classes (Tuple, Tuple, Tuple, and so on) and the Array class provide explicit implementations of the IStructuralEquatable interface. By casting (in C#) or converting (in Visual Basic) the current instance of an array or tuple to an IStructuralEquatable interface value and providing your IEqualityComparer implementation bey an argument to the Equals method, you can define a custom equality comparison for the array or collection.

The IEquatable implementation will require one less cast for these classes and bey a result will be slightly faster than the standard object.Equals method that would be used otherwise. Bey an example see the different implementation of the two methods:

When an implementer overrides the virtual Equals method in C# IStructuralEquatable nedir a struct, the purpose is to provide a more efficient means of performing the value equality check and optionally to base the comparison on some subset of the struct's field or properties.

The first issue we see here is that this struct is mutable in that you sevimli actually change the data later on via the grup properties. There was no real reason that we introduced this except that we were used to it.

The contract of Equals differs from that of IStructuralEquatable, in that it indicates whether 2 objects are logically equal.

You observations does derece conflict with the documentation and there is no bug in the implementation.
