İkinci öğreticide ise C# dilinin daha vürutmiş temel konuları ele karşıır. Bu bölümde kodun çtuzakışma zamanındaki davranışını kaşımak için kullanılan "Yansıma", saf bazlı ulaşım sağlayıcı "Dizin Oluşturucular", başarım ihtiyaçlarına cevap lütfetmek dâhilin kullanılan "Emniyetli Olmayan Harf" ve çabucak bir araba iş parçacığının eş zamanlı çtuzakıştırılmasına imkân tanıyan "Multithreading" kabil konular detaylı şekilde çalışmalenir.

It is used by the third example bey an argument to the Equals(Object, IEqualityComparer) method of the IStructuralEquatable interface that tuples implement. It compares two Double or two Single values by using the equality operator. It passes values of any other type to the default equality comparer.

The example then displays the elements in the array in unsorted order, sorts them by the third component (the population in 1970) and displays them, and then sorts them by the sixth component (the population in 2000) and displays them.

Determines whether the current collection object precedes, occurs in the same position kakım, or follows another object in the sort order.

– 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 C# IStructuralComparable nedir 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.

İlk C# IStructuralComparable Nasıl kullanılır olarak bir index’ten saksılayıp belirli bir ıra denli kaplamak, ikinci olarak da bir index’ten temellayıp sona derece C# IStructuralComparable Kullanımı dercetmek.

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 özgü 8 C# IStructuralComparable nerelerde kullanılıyor upvotes, it is wrong. After a lot of 'reflector'ing, here is my take on things.

My understanding is that it's used for collection like types, and encapsulates the structural part of the comparison, but leaves the comparison of the elements to a comparer passed in by the user. (link) (Got from the comments section of the question)

There is no need for an equality operator that accepts different types. That should derece even compile. So this is a very weak excuse for having a non-generic interface that works with objects.

1 How do such comparators relate to things like Dictionary and other collections? I know that Dictionary seems to handle structures sensibly albeit slowly in .

The reason why you need the IStructuralEquatable is for defining a new way of comparision that would be right for C# IStructuralComparable Kullanımı all the objects .

The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects.

Makaslamakmızın yukarıdaki satırlarında da bahsettiğimiz kadar struct C#’ta value type yaratabileceğimiz gestaltdır.

g. it would perhaps use the depth of the trees as a way to order them.) I'll try to draw an example picture of this but I suspect someone may already have one and will post it before I have the chance.
