However, this is an implementation detail and unless you want to rely on this in your code you cannot create a stable hash code provide an object that implements IStructuralEquatable.

= to provide value equality checks (vs the default reference equality check). The MSDN documentation suggests you only do it for immutable types. There are also issues involving interfaces and operator overloading.

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.

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 kişi use .NET tuples or anonymous types to create hash codes by combining values but I am derece sure this answers your question.

comparer IEqualityComparer An object that determines whether the current instance and other are equal.

IStructuralEquatable is quite new and unknown, but I read somewhere that it kişi be used to compare the contents of collections and arrays. Am I wrong, or is my .Safi wrong?

Ayrıksı bir ifadeyle, kendi konstrüktif muadelet teşhismınızı oluşturabilir ve bu tanılamamın arabirimi kabul IStructuralEquatable eden bir koleksiyon türüyle kullanılacağını belirtebilirsiniz. Arabirimin iki üyesi vardır: Equals, belirtilen IEqualityComparer bir uygulamayı kullanarak eşitliği test eder ve GetHashCodeeşit olan nesneler için aynı karma kodları döndürür.

Will feeblemind affect the original creature's body when it was cast on it while it was polymorphed and reverted to its original form afterwards?

There is no need for an equality operator that accepts different types. That should not even compile. So this is a very weak excuse for having a non-generic interface that works with objects.

While writing my own immutable ByteArray class that uses a byte array internally, I implemented the IStructuralEquatable interface.
