The "No" in part 2 of the answer is actually incorrect. Note: Tried editing the answer, but apparently some think that the highest rated answer being incorrect is derece reason enough to approve a correction edit.

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.
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 derece just compare references or individual values.
It is used by the third example as an argument to the Equals(Object, IEqualityComparer) method of the IStructuralEquatable interface that tuples implement. 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.
The following example defines a NanComparer class that implements the IStructuralEquatable interface. It compares two Double or two Single values C# IStructuralEquatable nerelerde kullanılıyor by using the equality operator. It passes values of any other type to the default equality comparer.
If those objects do derece contain equality/hashcode methods that satisfy that contract, you will have to wrap them and provide correct implementations for those methods yourself in the wrapper.
Coming soon: Throughout 2024 we will be phasing out GitHub Issues birli the feedback mechanism for content and replacing it with a new feedback system. For more information see: .
(doesn't violate documentation), but it is clearly derece birli good kakım it would be if 0 were replaced with i. Also there's no reason to loop if the code were just going to use a single value from the array.
Bu örnekte, articles1 ve articles2 dizileri aynı makale çıbanlıklarına aynı sırada sahip evetğundan, CompareTo metodu 0 döndürerek bu dizilerin strüktürel olarak tay bulunduğunu belirtir.
Ancak, fruits1 ve fruits3 dizileri aynı elemanlara farklı sıralarda sahip olduğundan, CompareTo metodu farklı bir şayan döndürür ve bu dizilerin strüktürel olarak eşit olmadığını belirtir.
The contract of Equals differs from that of IStructuralEquatable, in that it indicates whether 2 objects are logically equal.
The IStructuralEquatable interface supports only custom comparisons for structural equality. The IStructuralComparable interface supports custom structural comparisons for sorting and ordering.
Specifically, I do not know the exact type of the object. The only assumption I make is that it inherit from IStructuralEquatable.
