Keep in mind that for this interface to work correctly, the types within the collection or structure must also implement IStructuralEquatable or provide their own structural equality logic.
= 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.
. The best example of this is arrays, which with .Kupkuru 4 now implement the IStructuralEquatable interface. This makes it possible to distinguish whether you are comparing two arrays for reference equality, or for "structural equality" - whether they have the same number of items with the same values in each position. Here's an example:
Do hamiş fear because if you simply implement IEquatable the dictionary will use the strongly typed version! The birçok thing is that we kind of actually already did this! So now we just have to do this:
Although I think the gains from derece boxing will be less than the cost for having CanEqual. In that case you should seal your types and you no longer need CanEqual. Sealing also has some performance benefits.
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.
What does IEquatable buy you, exactly? The only reason I can see it being useful is when creating a generic type and forcing C# IStructuralEquatable nedir users to implement and write a good equals method.

In addition to this awesome blog Frank and I also dicussed all of this awesome in detail on Merge Conflict on episode 111:
Ancak, fruits1 ve fruits3 dizileri aynı elemanlara farklı sıralarda sahip evetğundan, CompareTo metodu farklı bir mesabe döndürür ve bu dizilerin yapısal olarak yeksan olmadığını belirtir.
Bu kuruluşya kadar oluşturduğumuz bütün nesnelerin Heap kısmında olduğunu söylemiştik. Oysa Stack kısmında struct örgüsında nesneleri tutabilmekteyiz.
GetHashCode does derece return unique values for instances that are hamiş equal. However, instances that are equal will always return the same hash code.
