C# IStructuralEquatable Kullanımı Üzerinde Buzz söylenti

Wiki Article

However, this is an implementation detail and unless you want to rely on this in your code you cannot create a stable hash code provide an object that implements IStructuralEquatable.

= 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.

Does anyone know what happens if you do hamiş implement iequtalable when using generic collections? 2

This code technically works, but is sort of a hot mess and is not really maintainable. Anyone using the library would have to write this code birli well. The next logical step would be to just use .Equals on the entire metrics.

The following example defines a NanComparer class that implements the IStructuralEquatable interface. It compares two Double or two Single values by using the equality operator. It passes values of any other type to the default equality comparer.

IStructuralEquatable is quite new and unknown, but I read somewhere that it hayat be used to compare the contents of collections and arrays. Am I wrong, or is my .Kemiksiz wrong?

Defines a generalized method that a value type or class implements to create a type-specific method for determining equality of instances.

Gayrı bir ifadeyle, kendi konstrüktif müsavat tanılamamınızı oluşturabilir ve bu C# IStructuralEquatable Kullanımı tanımın arabirimi kabul IStructuralEquatable eden bir koleksiyon türüyle kullanılacağını belirtebilirsiniz. Arabirimin iki üyesi vardır: Equals, tamlanan IEqualityComparer bir uygulamayı kullanarak eşitliği test paha ve GetHashCodeeşit olan nesneler yürekin aynı kompozit kodları döndürür.

I had the same question. When I ran LBushkin's example I was surprised to see that I got a different answer! Even though that answer başmaklık 8 upvotes, it is wrong. After a lot of 'reflector'ing, here is my take on things.

To achieve this, employee objects with matching SSN properties would be treated kakım logically equal, even if they were derece structurally equal. Share Improve this answer Follow

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

Are the bonuses for infernal war machine weapon stations static, or are they affected by their user?
