Enum tanılamamlarken şayet herhangi bir paha verilmezse defaul olarak 0 dan temellayarak kıymetiharbiye vermeye adım atar . Burada

The comparer doesn't handle Dictionary, since you're only looking for IList; if you started looking for IEnumerable (and added a special case for KeyValuePair) it would handle dictionaries birli well

That means that your BaseClassComparer constrains the result type to base class and the conversion at the assignment is not possible.

I've added to my class the IEqualityComparer implementation, derece sure if the code bellow is the correct one, especially the Equals(object x, object y) functions: should we override or make a new implementation of the Equals method, like this: ?

I would say that the best use would be when you need to plug in different equality rules for a certain algorithm. Much in the same way that a sorting algorithm might accept an IComparer, a finding algorithm might accept an IEqualityComparer

 In the plain case, when we need to drop only exact duplicates, the simple Distinct() call will do. The simplest possible example is getting unique integers from a collection of numbers:

You have discovered an unfortunate edge case in the generic method type inference algorithm. We C# IEqualityComparer Nasıl Kullanılır have:

The dictionary is recreated with an equality comparer that defines equality in a different way: Two boxes are considered equal if their volumes are the same.

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