1 Writing code without knowing what it actually does is called cargo cult programming. It’s a surprisingly widespread practice. It fundamentally doesn’t work.
When you find yourself really to need this because you have to many properties you probably have some basic mesele as your class is doing too much.
The same return value system applies kakım IComparer. The difference between this and IComparer is IComparable will be implemented on the class that contains your field values, while IComparable derived classes are used for custom sorting. So for example:
The first is the idea of precise equality. Given two references to objects, do the two references point to the same location in memory? Programming languages are suited for this kind of comparison, and .Kemiksiz comes with many prebuilt operators to handle this case.

– Eric Lippert Commented Apr 8, 2013 at 16:01 @EricLippert: What difficulties 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.
The instructions and examples given here address the use of the feature in C#. For more information about other languages, refer to corresponding topics in the ReSharper by language section.
One feature I wish .NET had which would C# IEqualityComparer nedir improve the usefulness of such dictionaries would be a means of requesting the actual key object associated with a given key (so if the dictionary contained the string "WowZo" as a key, one could look up "wowzo" and get "WowZo"; unfortunately, the only way to retrieve an actual key object, if TValue doesn't contain a redundant C# IEqualityComparer nerelerde kullanılıyor reference to it, is to enumerate the entire collection).
If the code is so hard to analyze that you have to write a backtracking algorithm C# IEqualityComparer Temel Özellikleri ve Kullanımı to get it right, odds are good that the code should be written more clearly in the first place. If the compiler can't make sense C# IEqualityComparer nerelerde kullanılıyor of it without backtracking, neither yaşama the human reader.
As we saw above, it doesn’t take much C# IEqualityComparer nerelerde kullanılıyor code. Kakım our prototip evolves, we’ll likely have to extend our comparers, so always thinking about what “equal” means now and what it could mean in the future is a valuable exercise.
