The "No" in part 2 of the answer is actually incorrect. Note: Tried editing the answer, but apparently some think that the highest rated answer being incorrect is derece reason enough to approve a correction edit.
= 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 .NET 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:
IStructuralComparable arayüzü, ekseriya Array ve Tuple kadar veri binaları aracılığıyla uygulanır. Bu bilgi gestaltları, elemanlarının sıralamasını ve yapısını dikkate alarak önlaştırma yapar.
In this equating the values in arrays may be same or different but their object references are equal.
The generic tuple classes (Tuple, Tuple, Tuple, and so on) and the Array class provide explicit implementations of the IStructuralEquatable interface. By casting (in C#) or converting (in Visual Basic) the current instance of an array or tuple to an IStructuralEquatable interface value and providing your IEqualityComparer implementation bey an argument to the Equals method, you güç define a custom equality comparison for the array or collection.
1 My understanding is that it's used for collection like types, and encapsulates the structural part of the comparison, but leaved the comparison of the elements to a comparer passed in by the user. But I'm derece really sure if I really got it.
This is very disappointing behaviour from Microsoft; I'm now wondering if I should review the list of cases I've filed and see if other ones I've submitted have been removed...
The reason why you need the IStructuralEquatable is for defining a new way of comparision that would be right for all the objects .

Amma velakin bu yapımız class derece kompleks anlayışlemler için tasarlanmış bir yapı gerektirmiyorsa ve tutulacak verileri enkapsüle buyurmak yetiyorsa işte bu usul durumlarda struct yapkaloriı yeğleme edebiliriz.
Do hamiş send hash codes across application domains or processes. In some cases, hash codes may be computed on a per-process or per-application domain basis.
Are the bonuses for infernal war machine weapon stations static, or are they affected by their user?
The Equals method supports custom structural comparison of array and tuple objects. This method in turn calls the comparer object's IEqualityComparer.Equals method to compare individual array elements or tuple components, starting with the first element or component.
