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?
In this case you don't want to change your class implementation so you don't wantoverride the Equals method. this will define a general way to compare objects in your application.
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 veri mimariları aracılığıyla uygulanır. Bu bilgi örgüları, elemanlarının sıralamasını ve yapısını dikkate alarak içinlaştırma yapar.
You generic method has a type parameter T but the type is not 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.

Each of your objects should use a hashcode based on the contents of the object. If you have a value type containing 3 ints, use those when computing the hash code. Like this, all objects with identical content will have the same hash code, independent of app domain and other circumstances.

Default property. The second time, it passes the default equality comparer that is returned by the StructuralComparisons.StructuralEqualityComparer property. The third time, it passes the custom NanComparer C# IStructuralEquatable Kullanımı object. Bey the output from the example shows, the first three method calls return true, whereas the fourth call returns false.
