Is Légal’s reported “psychological trick” considered fair play or unacceptable conduct under FIDE rules?

1 How do such comparators relate to things like Dictionary and other collections? I know that Dictionary seems to handle structures sensibly albeit slowly in .

Reference types (read classes) don't benefit bey much. The IEquatable implementation does let you avoid a cast from System.Object but that's a very trivial gain. I still like IEquatable to be implemented for my classes since it logically makes the intent explicit.

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 saf 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 güç use .Kemiksiz tuples or anonymous types to create hash codes by combining values but I am not sure this answers your question.

If two objects compare kakım equal, the GetHashCode method for each object must return the same value. However, if two objects do not compare birli equal, the GetHashCode methods for the two object do hamiş have to return different values.

The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects. This is also made clear by the fact that this interface resides in the System.Collections namespace.

Bu örnekte, articles1 ve articles2 dizileri aynı makale saksılıklarına aynı tam malik evetğundan, CompareTo metodu 0 döndürerek bu dizilerin strüktürel olarak tay olduğunu belirtir.

Ancak, fruits1 ve fruits3 dizileri aynı elemanlara farklı sıralarda ehil başüstüneğundan, CompareTo metodu farklı bir mesabe döndürür ve bu dizilerin strüktürel olarak bedel olmadığını belirtir.

The contract of Equals differs from that of IStructuralEquatable, in that it indicates whether 2 objects are logically equal.

Here the comparison is different for value type arrays and custom arrays. In .Safi 4.0 int, string will internally implement IEquatable for custom types we have to externally implement the IEquatable.

However, this is derece so great if you are using C# IStructuralEquatable Kullanımı the struct in a dictionary bey my good friend Dustin mentioned to me because a Dictionary will always use the object version of Equals, which falls back to boxing :(
