I think the pool logic might be broken; you're adding objects which you see to the pool, and if the objects are on the pool then they're considered the same. It will işleyen if you have two objects of type A with three properties kakım shown below:

If the class is defined in such a way that you emanet't define it as IEquatable. This would include classes defined by others and classes generated by the compiler (specifically anonymous types, which use a property-wise comparison by default).

If you're not assigning to anything, you'll need to. Distinct() returns an IEnumerable rather than doing an in place update

Bir dahaki sefere tefsir yapmış olduğumda kullanılmak üzere kademı, e-posta adresimi ve web site adresimi bu tarayıcıya kaydet.

This interface allows the implementation of customized equality comparison for collections. That is, you gönül create your own definition of equality, and specify that this definition be used with a collection type that accepts the IEqualityComparer interface.

If you change your class to implement IEquatable instead, the implementation of Distinct (which will use EqualityComparer.Default which in turn sees your type implements IEquatable and delegates to that) will work kakım you expect.

Are there substantive differences between the different approaches to "size issues" in category theory?

After inspecting multiple SO questions and answers related to the topic as well kakım some other articles C# IEqualityComparer Temel Özellikleri ve Kullanımı I have both found the solution that fitted my needs for the moment and got some understanding of the way IEqualityComparer is actually used by LINQ operators. C# IEqualityComparer Nasıl Kullanılır Here I will try to explain what I got from there.

– Eric Lippert Commented Apr 8, 2013 at 16:01 @EricLippert: What difficulties C# IEqualityComparer nerelerde kullanılıyor would arise if one allowed return type to be considered in method overloading only in cases where the return type was either being coerced to a particular type, or was passed to a method where all overloads of proper arity had the same type for that parameter (e.

Hassaten Yazılı sınavma Görünmek Mı İstiyorsunuz? Görmeniz Lüzumlu! kafalıklı kırma da irsal edinmek istedim. Bu makaslamakmda yaşadığım bu durumdan linkeki makalemda uzun uzun bahsetmiştim. :D

However, quite frequently we, C# programmers, use classes and want to get rid of duplicated objects in a collection the same way. Suppose, we do something with actors of a movie:

If the code is so hard to analyze that you have to write a backtracking algorithm to get it right, odds are good that the code should be written more clearly in the first place. If the compiler dirilik't make sense of it without backtracking, neither dirilik the human reader.

It is all very easy when the context is an assignment to a variable of C# IEqualityComparer nerelerde kullanılıyor 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.
