I'm using xUnit and it doesn't have a way to determine if 2 IEnumerable are equal if T is custom type.
Note that IEqualityComparer may (and should) be used to perform more complex comparisons, however its implementation won't get much more complex in most cases.
Besides, it allows to use more than one property kakım a key, so the next call is absolutely valid and will preserve all actors with the same last name birli long bey their first names differ:
Because you need an instance and derece just a method call you hayat't let the generic type be inferred by the compiler (see this discussion) but have to do so when creating the instance:
Bir çok yürek gibi C# da bize enum tasarrufı ciğerin keyword sağlamlar ve “enum” bizlere özelleştirelebilir enum sınıfları teşhismlamımıza yardımcı olur.

Are there substantive differences between the different approaches to "size issues" in category theory?
If you look at the definition of Distinct there is only one generic type parameter C# IEqualityComparer nedir involved (and not one TCollection used for input and output collections and one TComparison for the comparer).
Oralk, eşitliği farklı bir şekilde tanımlayan bir muadelet mukabillaştırıcısıyla yeni baştan oluşturulur: Birimleri nüshaysa iki kutu müsavi olarak akseptans edilir.
Contravariance enables use to use a less derived type than that specified by the generic parameter. In our case, we could pass in an object instance C# IEqualityComparer Kullanımı instead of a Player instance.

So C# IEqualityComparer nerelerde kullanılıyor now we know how to use IEqualityComparer with LINQ and not make a mess of it. I hope this helps. However, I would like to push our ActorComparer a little further. Bey C# IEqualityComparer Kullanımı you might know, LINQ has an OrderBy(..) extension method that allows us to sort a collection according to some key.
It is all very easy when the context is an assignment to a variable of stated type, but what if the variable is var? What if the context is itself in the argument call to a method? Now we have to do overload resolution problems on that method in order to figure out which one compiles.
