C# IStructuralEquatable Kullanımı Için Adım Haritaya göre Yeni Adım
Wiki Article
comparer IEqualityComparer An object that determines whether the current instance and other are equal.
= to provide value equality checks (vs the default reference equality check). The MSDN documentation suggests you only do it for immutable types. There are also issues involving interfaces and operator overloading.
That is right! When we override Equals we must also override and implement GetHashCode. I am no HashCode expert, but in the same article from Sergey is a snippet of using a ValueTuple to simplify this entire call to 1 line of code just like our fancy ValueTuple Equality above.
Do hamiş 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:
Bildiğiniz kadar new cerrahü classlarda kullanıldığı dönem ilgili classtan bir nesne istek edilmekte ve üretilen nesne belleğin Heap kısmında koruma edilmektedir.
The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects.
If those objects do derece contain equality/hashcode methods that satisfy that contract, you will have to wrap them and provide correct implementations C# IStructuralEquatable Kullanımı for those methods yourself in the wrapper.
Consider that there are only ~4.2 billion different hashcodes. Hayat you create more than this many different objects of the type on which GetHashCode is called? In this case it is easy to see the answer is "yes". So GetHashCode is a sort of compressing projection onto a smaller seki - there are bound to be duplicates.

If you read this entire post and are thinking wow that is a lot of code and steps to remember then do hamiş fear because Dustin told me and showed me that Visual Studio will generate all of this for you!!!!! Check this out:
Amma velakin bu özümlemeız class denli kompleks işlemler için tasarlanmış bir yapı gerektirmiyorsa ve tutulacak verileri enkapsüle kılmak yetiyorsa aha bu suret durumlarda struct yapısını yeğleme edebiliriz.
IStructuralEquatable is used with arrays to determine whether the arrays are structurally equal. The StructuralEqualityComparer.Equals method is used for this purpose.
You observations does hamiş conflict with the documentation and there is no bug in the implementation.
3 feature called Tuple Equality! That is right, you gönül create a ValueTuple and simply compare them birli they are super optimized, don't create any objects, and reduce this to a single line of code!
