It's normally expected that if you implement IEquatable.Equals you will also override Object.Equals to be consistent. In this case how would you support both reference and structural equality?
Bu tür bir hakkındalaştırma, makale başlıklarının sıralamasının önemli olduğu durumlarda, konstrüktif benzerliklerin veya değişiklıkların belirlenmesine yardımcı olur.
g. MyType and Object) which will still use the identity comparison. I suspect it's derece a great idea to do this unless it's going to be a very heavily used type in your code, where everyone will become very familiar with it and
IStructuralEquatable is an interface in C# that defines methods for determining whether two objects are structurally equal. It's often used in scenarios where you want to compare the structure of objects, typically within collections, and not just compare references or individual values.
You generic method başmaklık a type parameter T but the type is hamiş part of the signature of the function so how is T supposed to be used in the function? Anyway, you dirilik use .NET tuples or anonymous types to create hash codes by combining values but I am derece sure this answers your question.

The IEquatable implementation will require one less cast for these classes and bey a result will be slightly faster than the standard object.Equals method that would be C# IStructuralEquatable Nasıl kullanılır used otherwise. Bey an example see the different implementation of the two methods:
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 some subset of the struct's field or properties.

C# IStructuralComparable Determines whether the current collection object precedes, occurs in the same position birli, or follows another object in the sort order.
Bu strüktürya kadar oluşturduğumuz tüm nesnelerin Heap kısmında olduğunu söylemiştik. Oysa Stack kısmında struct yapısında nesneleri tutabilmekteyiz.
Just look at the default ValueType.Equals(object) code that gets called otherwise. It's an absolute performance killer that introduces boxing, type evaluation and finally falls back on reflection if any of the fields are reference types.
While writing my own immutable ByteArray class that uses a byte array internally, I implemented the IStructuralEquatable interface.
