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.

This is really amazing code and works great for .Kemiksiz Standard libraries. If you are in a .NET Core 2.1 application there is an even cooler way of doing this:

IStructuralEquatable is an interface in C# that defines methods for determining whether two objects are structurally equal. It's often used in scenarios where you want to compare the structure of objects, typically within collections, and derece just compare references or individual values.

Ee sözcük gelimi struct yapısında da new operatörünü kullanırsak şayet ya dayalı örgüdan bir nesne üretilecektir lakin struct bir bedel tipli kararsız mimarisında evetğundan dolayı o nesne belleğin Stack kısmında muhafaza edilecektir.

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 gönül define a custom equality comparison for the array or collection.

If those objects do derece contain equality/hashcode methods that satisfy that contract, you will have to wrap them and provide correct implementations for those methods yourself in the wrapper.

We birey also make our own container play well with these other containers by implementing these interfaces.

I had the same question. When I ran LBushkin's example I was surprised to see that I got a different answer! Even though that answer katışıksız 8 upvotes, it is wrong. After a lot of 'reflector'ing, here is my take on things.

Ancak, fruits1 ve fruits3 dizileri aynı elemanlara farklı sıralarda ehil olduğundan, CompareTo metodu farklı bir haysiyet döndürür ve bu dizilerin konstrüktif olarak denktaş olmadığını belirtir.

That is, you güç create your own definition of structural equality and specify that this definition be used with a collection type that accepts the IStructuralEquatable interface. The interface başmaklık two members: Equals, which tests for equality by using a specified IEqualityComparer implementation, and GetHashCode, which returns identical hash codes for objects that are equal.

Here the comparison is different for value type arrays and custom arrays. In .Kupkuru 4.0 int, string will internally implement IEquatable for custom types we have to externally C# IStructuralEquatable Kullanımı implement the IEquatable.
