Keep in mind that for this interface to work correctly, the types within the collection or structure must also implement IStructuralEquatable or provide their own structural equality logic.

Now, when we call Equals ourselves it will directly call our new fancy Equals that takes in a ScreenMetrics, which is great.

Reference types (read classes) don't benefit kakım much. The IEquatable implementation does let you avoid a cast from System.Object but that's a very trivial gain. I still like IEquatable to be implemented for my classes since it logically makes the intent explicit.

Do not fear because if you simply implement IEquatable the dictionary will use the strongly typed version! The nice thing is that we kind of actually already did this! So now we just have to do this:

I'm amazed that the most important reason is hamiş mentioned here. IEquatable was introduced mainly for structs for two reasons:

comparer IEqualityComparer An object that determines whether the current instance and other are equal.

The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects. This is also made clear by the fact that this interface resides in the System.Collections C# IStructuralEquatable Nasıl kullanılır namespace.

Doğrusu anlayacağınız “int” kabil, “bool” gibi mesabe tipli bir oynak tesis etmek istiyorsanız struct yapısını yeğleme edebilirsiniz.

Bu örnekte, articles1 ve articles2 dizileri aynı makale temellıklarına aynı tam malik başüstüneğundan, CompareTo metodu 0 döndürerek bu dizilerin konstrüktif olarak hemayar olduğunu belirtir.

Net on a certain platform, I'm compelled to issue the standard warning hamiş to rely on the values of hashcodes or how they are computed, since it is derece guaranteed to be the same across updates or platforms.

That is, you dirilik create your own definition of structural equality and specify that this definition be used with a collection type that accepts the IStructuralEquatable interface. The interface has two members: Equals, which tests for equality by using a specified IEqualityComparer implementation, and GetHashCode, which returns identical hash codes for objects that are equal.

Specifically, I do not know the exact type of the object. The only assumption I make is that it inherit from IStructuralEquatable.
