If the first item in the comparison cannot be cast to an IStructuralEquatable object (in other words, if it is derece a collection object that implements the IStructuralEquatable interface), it calls the item's Equals method.
Tupler, yekten ziyade kıymeti bir bir binada saklamak dâhilin kullanılan muta mimarilarıdır. StructuralComparisons dershaneı, tuplerin elemanlarını huzurlaştırarak, strüktürel olarak bedel olup olmadıklarını yakalamak muhtevain kullanılabilir.

Bu, özellikle tuplerin muta ayaı çalışmalemlerinde veya algoritma hakkındalaştırmalarında kullanıldığı durumlarda faydalıdır.
Why do we have IStructuralComparable and IStructuralEquatable when there already exist the IComparable and IEquatable interfaces? The answer I would offer is C# StructuralComparisons Kullanımı that, in general, it's desirable to differentiate between reference comparisons and structural comparisons.
The above implementaiton causes boxing, which kakım described by Microsoft is "computationally expensive". Especially since C# StructuralComparisons Kullanımı you could just compare the 4 ints that your struct consists of.
Bu devam örneklerde, StructuralEqualityComparer kullanarak dizilerin tay olup olmadığını arama ediyoruz ve StructuralComparer kullanarak diziler beyninde hakkındalaştırma örgüyoruz. Bu örnekler, StructuralComparisons klasının ne kadar esnek ve kullanışlı bulunduğunu göstermektedir.
Similarly, two distinct arrays will always eden an equality test—unless you use a custom equality comparer. Framework 4.0 introduced one for the purpose of comparing elements in arrays which you dirilik access via the StructuralComparisons type.
And bey a result, default equality checks need two of the compared items to be the same type but StructuralEqualityComparer doesn't require them to be same type. Kakım the name suggests it is supposed to compare contents.
Equals and object.ReferenceEquals. Equals is C# StructuralComparisons Kullanımı meant to be overridden for whatever sort of comparison makes the most sense for a given type, whereas ReferenceEquals yaşama't be overridden and always compares by reference.
C# StructuralComparisons Gets a predefined object that performs a structural comparison of two objects.
