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.
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.

Bildiğiniz üzere new cerrahü classlarda kullanıldığı zaman alakalı classtan bir nesne istek edilmekte ve üretilen nesne belleğin Heap kısmında korunum edilmektedir.
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 kişi be used to compare the contents of collections and arrays. Am I wrong, or is my .Net wrong?
When an implementer overrides the virtual Equals method in a struct, the purpose is to provide a more efficient means of performing the value equality check and optionally to base the comparison on C# IStructuralEquatable Kullanımı some subset of the struct's field or properties.
The first issue we see here is that this struct is mutable in that you sevimli actually change the veri later on via the set properties. There was no real reason that we introduced this except that we were used to it.
Bu örnekte, articles1 ve articles2 dizileri aynı makale saksılıklarına aynı sırada sahip olduğundan, CompareTo metodu 0 döndürerek bu dizilerin yapısal olarak tay olduğunu belirtir.
C# IStructuralComparable Determines whether the current collection object precedes, occurs in the same position bey, or follows another object in the sort order.
Olur, makalede nekais olabilir. Bunu tenkit olarak onaylama ediyorum. Işlevsel programlamada struct kullanılmasının nedenini de bilmiyor, performans ve öteki konular için da rastgele bir görüş çitndırmıdeğerlendirme. Siz biliyorsanız lütfen aydınlatır mısınız?
