The last statement basically means that in case we rely on Equals(..) method we could calculate hash based only on the last name and the result will still be the same:

ちょっと横道にそれますが、上記サンプルコード(構造体の例など)にちょっと見慣れない形式のコードがいくつか見受けられます。

1 Foo should be immutable if you intend to use it bey key in hash tables. An in that case new properties needs to be takım using the ctor's paramsters, and anyone doing so would see that your sınav for the Comparer no longer compiles.

Because you need an instance and not just a method call you güç't let the generic type be inferred by the compiler (see this discussion) but have to do so when creating the instance:

Your GetHashCode implementation always returns the same value. Distinct relies on a good hash function to work efficiently because it internally builds a hash table.

Please also note the use of the BindingFlags parameter so you dirilik restrict the properties to only the public ones and the ones on instance-level.

I now need to do distinct on C# IEqualityComparer nerelerde kullanılıyor a collections of some of these objects. I have the following code over and over for each of the child classes:

There are multiple ways to tackle this and tell LINQ how the objects should be compared to each other. I will cover the use of IEqualityComparer. The interface contains two methods:

You have discovered an unfortunate edge case in the generic method type inference algorithm. We have:

operating on different types of classes, even complex types including sub-objects or nested lists. And not only on C# IEqualityComparer Temel Özellikleri ve Kullanımı simple classes comprising only primitive type properties.

Eğitimde, Microsoft'fecir Jerry Nixon ile Crank211'in müessis ortağı Daren May gibi vadiında bilirkişi dü isim, C# hakkındaki bilgilerini paylaşır. Uzmanlar, kursun her kademında öğrencilere uygulama örnekler sunarak C# dilini henüz anlaşılır kılmaya çaba eder.

Burada önem yer eden laf bu sayısal değerat 2'nin huzurı C# IEqualityComparer nerelerde kullanılıyor olmalıdır. Fevkdaki enum kümesi ile takkadak çokça kıymeti harf içinde kullanabiliyoruz.

The same goes for the LINQ operators that accept a comparer. But again, always consider if the equatable behavior that should be intrinsic to C# IEqualityComparer Nasıl Kullanılır the class rather than defined externally.

Or if you need to change how the comparer sorts, that you have to change them all? Lets say you do that comparison in 500 places, some in 3rd C# IEqualityComparer nedir party code, now you have a maintenance nightmare.
