It differs from reference equality, which indicates that two object references are equal because they reference the same physical object.
Default property. The second time, it passes the default equality comparer that is returned by the StructuralComparisons.StructuralEqualityComparer property. The third time, it passes the custom NanComparer object. Bey the output from the example shows, the first three method calls return true, whereas the fourth call returns false.
Ee güfte gelimi struct konstrüksiyonsında da new operatrisünü kullanırsak şayet ya ilgili binadan bir nesne üretilecektir lakin struct bir ölçü tipli değişken strüktürsında başüstüneğundan dolayı o nesne belleğin Stack kısmında koruma edilecektir.
The generic tuple classes (Tuple, Tuple, Tuple, and so on) and the Array class provide explicit implementations of the IStructuralEquatable interface. By casting (in C#) or converting (in Visual Basic) the current instance of an array or tuple to an IStructuralEquatable interface value and providing your IEqualityComparer implementation kakım an argument to the Equals method, you emanet define a custom equality comparison for the array or collection.
1 My understanding is that it's used for collection like types, and encapsulates the structural part of the comparison, but leaved the comparison of the elements to a comparer passed in by the user. But I'm not really sure if I really got it.
The following example creates two identical 3-tuple objects whose components consist of three Double C# IStructuralEquatable Kullanımı 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 observations does not conflict with the documentation and there is no bug in the implementation.
3 feature called Tuple Equality! That is right, you can create a ValueTuple and simply compare them as they are super optimized, don't create any objects, and reduce this to a single line of code!
