comparer IEqualityComparer An object that determines whether the current instance and other are equal.

= 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.

Reference types (read classes) don't benefit bey much. The IEquatable implementation does let you avoid a cast from System.Object but that's a very trivial gain. I still like IEquatable to be implemented for my classes since it logically makes the intent explicit.

I'm amazed that the most important reason is not 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.

What does IEquatable buy you, exactly? The C# IStructuralEquatable nerelerde kullanılıyor only reason I hayat see it being useful is when creating a generic type and forcing users to implement and write a good equals method.
