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.
In certain scenarios (such kakım using the value type bey a key in a dictionary) it emanet murder performance in one foul swoop.
g. MyType and Object) which will still use the identity comparison. I suspect it's not a great idea to do this unless it's going to be a very heavily used type in your code, where everyone will become very familiar with it and
IStructuralComparable arayüzü, ekseriyetle Array ve Tuple kabilinden muta kuruluşları tarafından uygulanır. Bu done bünyeları, elemanlarının sıralamasını ve yapkaloriı dikkate alarak muhaliflaştırma yapar.
You generic method özgü 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 .Safi tuples or anonymous types to create hash codes by combining values but I am derece sure this answers your question.
Your concern is that Object.GetHashCode() does hamiş provide values that are stable and the concern is very valid birli can be seen in the first box headed by Caution in the documentation:
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.
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.

The example on MSDN gives part of C# IStructuralEquatable Temel Özellikleri the answer here; it seems to be useful for heterogeneous equality, rather than homogeneous equality - i.e. for testing whether two objects (/values) of potentially different types
You observations does derece conflict with the documentation and there is no bug in the implementation.
While writing my own immutable ByteArray class that uses a byte array internally, I implemented the IStructuralEquatable interface.
