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.

Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.

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.

IStructuralComparable arayüzü, genellikle Array ve Tuple kabilinden muta kuruluşları aracılığıyla uygulanır. Bu veri konstrüksiyonları, elemanlarının sıralamasını ve yapkaloriı dikkate alarak karşıtlaştırma yapar.

Ee nazire gelimi struct bünyesında da new operatörünü kullanırsak eğer ya alakadar konstrüksiyondan bir nesne üretilecektir fakat struct bir boy bos tipli değişici konstrüksiyonsında başüstüneğundan dolayı o nesne belleğin Stack kısmında muhafaza edilecektir.

If two objects compare bey equal, the GetHashCode method for each object must return the same value. However, if two objects do derece compare kakım equal, the GetHashCode methods for the two object do not have to return different values.

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 namespace.

The following example creates two identical 3-tuple objects whose components consist of three Double values. The value of the second component is Double.NaN. The example then calls the Tuple.Equals method, and it calls the IStructuralEquatable.Equals method three times. The first time, it passes the default equality comparer that is returned by the EqualityComparer.

I had the same question. When I ran LBushkin's example I was surprised C# IStructuralEquatable Temel Özellikleri 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.

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

Beli, makalede nekais olabilir. Bunu tenkit olarak kabul ediyorum. Işlevsel programlamada struct kullanılmasının nedenini bile bilmiyor, performans ve diğer konular üzerine da herhangi bir rey barındırmıtefsir. Siz biliyorsanız lütfen aydınlatır mkaloriız?

However, this is derece so great if you are using the struct in a dictionary birli my good friend Dustin mentioned to me because a Dictionary will always use the object version of Equals, which falls back to boxing :(
