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

It differs from reference equality, which indicates that two object references are equal because they reference the same physical object.

IStructuralEquatable is an interface in C# that defines methods for determining whether two objects are structurally equal. It's often used in scenarios where you want to compare the structure of objects, typically within collections, and hamiş just compare references or individual values.

In this equating the values in arrays may be same or different but their object references are equal.

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.

If those objects do not 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.

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

The reason why you need the IStructuralEquatable is for defining a new way of comparision that would be right for all the objects .

In Xamarin.Essentials we use the C# struct all over the place to encapsulate "small groups of related variables" for our event handlers. They are groups of veri that don't need to be created by the developers consuming the data and are only really used for reading the veri.

Kupkuru on a certain ortam, I'm compelled to issue the standard warning not 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 derece even compile. So this is a very weak excuse for having a non-generic interface that works with objects.

Being able to specify IStructuralEquatable/IStructuralComparable in such cases is actually useful. It C# IStructuralEquatable Temel Özellikleri would also be inconvenient to pass a TupleComparer or ArrayComparer everywhere you want to apply this type of comparison. The two approaches are not mutually exclusive.
