If two objects compare kakım equal, the GetHashCode method for each object must return the same value. However, if two objects do not compare bey equal, the GetHashCode methods for the two object do not have to return different values.

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.

If you want to implement IEquatable in a class hierarchy you emanet use the following pattern. It prevents derived (including sibling) classes from being equal.

Yazımızın fevkdaki satırlarında da bahsettiğimiz kadar struct C#’ta value type yaratabileceğimiz binadır.

You generic method katışıksız 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 birey use .Kupkuru tuples or anonymous types to create hash codes by combining values but I am hamiş sure this answers your question.

If two objects compare birli equal, the GetHashCode method for each object must return the same value. However, if two objects do derece compare as equal, the GetHashCode methods for the two object do not have to return different values.

If those objects do hamiş 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.

In my implementation I delegated the task of calculating hash codes to the internal array. While testing it, to my great surprise, I found that my two different arrays had the same structural hash code

Gayrı bir ifadeyle, kendi konstrüktif eşitlik teşhismınızı oluşturabilir ve bu teşhismın arabirimi onaylama IStructuralEquatable eden bir derlem türüyle kullanılacağını belirtebilirsiniz. Arabirimin dü üyesi vardır: Equals, belirtilen IEqualityComparer bir uygulamayı kullanarak eşitliği test eder ve C# IStructuralEquatable Temel Özellikleri GetHashCodeeşit olan nesneler midein aynı katışık kodları döndürür.

When working with collections or structures where the order of elements matters, and you want to compare their structures, IStructuralEquatable birey be useful.

Kupkuru on a certain platform, I'm compelled to issue the standard warning hamiş to rely on the values of hashcodes or how they are computed, since it is derece guaranteed to be the same across updates or platforms.

The contract of Equals differs from that of IStructuralEquatable, in that it indicates whether 2 objects are logically equal.

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.

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