You get a nice simple bool Equals(T other) function and there's no messing around with casting or creating a separate class.
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.
Another scenario where it may be useful to have an alternative means of comparison is when an object holds a reference to an instance a mutable type, but will never expose that instance to anything that might mutate it. In general, two instances of int[] that hold the same sequence of values will not be interchangeable, since it would be possible that in future one or both of them might be changed to hold different values.
I would like to get distinct objects from a list. I tried to implement IEqualityComparer but wasn't successful. Please review my code and give me an explanation for IEqualityComparer. public class Message

One feature I wish .Kemiksiz had which would 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 reference to it, is to enumerate the entire collection).
However, choosing the more C# IEqualityComparer Nasıl Kullanılır specific type Giraffe: return value hayat implicitly be cast to a larger type Animal if needed; and a return type of IEnumerable implicitly casts to IEnumerable. And that's the most used variant interface. I wonder why the more general type was chosen?
It is all very C# IEqualityComparer nerelerde kullanılıyor 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 C# IEqualityComparer Kullanımı to figure out which one compiles.
