That is, you sevimli create your own definition of structural equality and specify that this definition be used with a collection type that accepts the IStructuralEquatable interface.

= 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.

Hatmızın fevkdaki satırlarında da bahsettiğimiz kabil struct C#’ta value type yaratabileceğimiz strüktürdır.

After some more testing I found that any two arrays with the same first element have the same hash. I still think this is strange behavior.

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
