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

In certain scenarios (such birli using the value type as a key in a dictionary) it emanet murder performance in one foul swoop.

The following example creates two identical 3-tuple objects whose components consist of three Double values. The value of the second component is Double.NaN. The example then calls the Tuple.Equals method, and it calls the IStructuralEquatable.Equals method three times. The first time, it passes the default equality comparer that is returned by the EqualityComparer.

Equals and object.ReferenceEquals. Equals is meant to be overridden for whatever sort of comparison makes the most sense for a given type, whereas ReferenceEquals dirilik't be overridden and always compares by reference.

I'm amazed that the most important reason is hamiş mentioned here. IEquatable was introduced mainly for structs for two reasons:

The following example defines a NanComparer class that implements the IStructuralEquatable interface. 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.

After some more testing I found that any two arrays with the same first element have the same hash. I still think this is strange behavior.

We emanet also make our own container play well with these other containers by implementing these interfaces.

If you read this entire post and are thinking wow that is a lot of code and steps to remember then do derece fear because Dustin told me and showed me that Visual Studio will generate all of this for you!!!!! Check this out:

Amma velakin bu yapımız class kadar kompleks davranışlemler yürekin tasarlanmış bir yapı gerektirmiyorsa ve tutulacak verileri enkapsüle eylemek yetiyorsa işte bu hava durumlarda struct yapısını yeğleme edebiliriz.

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

GetHashCode does not return unique values for instances that are hamiş equal. However, instances that are equal will always return the same hash code.

3 feature called Tuple Equality! That is right, you can create a ValueTuple and simply compare them birli they are super optimized, don't create any objects, and reduce this to a single line of code!
