The individual calls to IEqualityComparer.Equals end and the IStructuralEquatable.Equals method returns a value either when a method call returns false or after all array elements or tuple components have been compared.
= 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.
That is right! When we override Equals we must also override and implement GetHashCode. I am no HashCode expert, but in the same article from Sergey is a snippet of using a ValueTuple to simplify this entire call to 1 line of code just like our fancy ValueTuple Equality above.
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 yaşama't be overridden and always compares by reference.
Ee güfte gelimi struct örgüsında da new operatörünü kullanırsak eğer ha müntesip örgüdan bir nesne üretilecektir yalnız struct bir bedel tipli değişici gestaltsında C# IStructuralEquatable nerelerde kullanılıyor evetğundan dolayı o nesne belleğin Stack kısmında korunum edilecektir.
– Royi Namir Commented Mar 3, 2012 at 18:04 @RoyiNamir user844541's answer is correct, but maybe it is still hard for you to understand without a concrete example, if you are familiar with IEqualityComparer and how it is used by Linq's Distinct(), then after check the source code to see how it implement IStructuralEquatable on referencesource.microsoft.com/#mscorlib/system/collections/…, then you will see how it work.

Specifically, I do derece know the exact type of the object. The only assumption I make is that it inherit from IStructuralEquatable.
