Other types which implement structural equality/comparability include tuples and anonymous types - which both clearly benefit from the ability to perform comparison based on their structure and content. A question you didn't ask is:

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.

I'm amazed that the most important reason is hamiş mentioned here. IEquatable was introduced mainly for structs for two reasons:

– 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.

The IEquatable implementation will require one less cast for these classes and bey a result will be slightly faster than the standard object.Equals method that would be used otherwise. Bey an example see the different implementation of the two methods:

Ancak, articles1 ve articles3 dizileri aynı makale çıbanlıklarına farklı sıralarda ehil olduğundan, CompareTo metodu farklı bir eder döndürür ve bu dizilerin strüktürel olarak hemayar olmadığını belirtir.

Reading through the excellent blog post by Sergey on struct equality performance he mentions that the default implementations are pretty slow and using boxing for each member. Additionally, he mentions that a memory comparison may hamiş give you the correct results in this super simple example:

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