That is, you emanet create your own definition of structural equality and specify that this definition be used with a collection type that accepts the IStructuralEquatable interface.

= 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.

It differs from reference equality, which indicates that two object references are equal because they reference the same physical object.

Default property. The second time, it passes the default equality comparer that is returned by the StructuralComparisons.StructuralEqualityComparer property. The third time, it passes the custom NanComparer object. As the output from the example shows, the first three method calls return true, whereas the fourth call returns false.

Although I think the gains from derece boxing will be less than the cost for having CanEqual. In that case you should seal your types and you no longer need CanEqual. Sealing also saf some performance benefits.

I never put much thought into using a struct over a class or even additional optimizations because to me the struct was optimized already. When I was working on fixing a bug in our DeviceDisplay to derece trigger new events unless a value changed a whole new world opened C# IStructuralEquatable Kullanımı up to me.

After some more testing I found that any two arrays with the same first element have the same hash. I still think this is strange behavior.

şu demek oluyor ki anlayacağınız “int” üzere, “bool” kabil porte tipli bir parametre tesis etmek istiyorsanız struct yapısını tercih edebilirsiniz.

The reason why you need the IStructuralEquatable is for defining a new way of comparision that would be right for all the objects .

In addition to this awesome blog Frank and I also dicussed all of this awesome in detail on Merge Conflict on episode 111:

Amma velakin bu özümlemeız class kadar kompleks teamüllemler bağırsakin tasarlanmış bir yapı gerektirmiyorsa ve tutulacak verileri enkapsüle geçirmek yetiyorsa işte bu janr durumlarda struct yapkaloriı yeğleme edebiliriz.

Do derece send hash codes across application domains or processes. In some cases, hash codes may be computed on a per-process or per-application domain basis.

3 feature called Tuple Equality! That is right, you sevimli 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!
