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 this case you don't want to change your class implementation so you don't wantoverride the Equals method. this will define a general way to compare objects in your application.

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?

Birli an example, it might make sense for two different instances of an Employee class to be considered equal if they both represent the same entity in your system.

Structural equality means that two objects are equal because they have equal values. It differs from reference equality, which indicates that two object references are equal because they reference the same physical object. The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects.

Defines a generalized method that a value type or class implements to create a type-specific method for determining equality of instances.

Programlama dillerinde en mühim OOP(Object Oriented Programing) binalarından olan class mimarisına bakılırsa henüz çarpık çurpuk düzeyde hizmetlemler gerçekleştirmemizi sağlayıcı ve belli başlı bir ekipman engellemelerı birlikte çitndıran struct yapkaloriı C# diline özel ele alacağız.

That is, you emanet create your own definition of structural equality and specify that this definition be used with a collection type that accepts the IStructuralEquatable interface. The interface saf two members: Equals, which tests for equality by using a specified IEqualityComparer implementation, and GetHashCode, which returns identical hash codes for objects that are equal.

Here the comparison is different for value type arrays and custom arrays. In .Kupkuru 4.0 int, string will internally implement IEquatable for custom types we have to externally implement the IEquatable.
