The last statement basically means that in case we rely on Equals(..) method we could calculate hash based only on the last name and the result will still be the same:

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.

If there is only one way of testing two instances of T for equality, or if one of several methods is preferred, then IEquatable would be the right choice: This interface is supposed to be implemented only by T itself, so that one instance of T has internal knowledge of how to compare itself to another instance of T.

IEqualityComparer is an interface for an object that performs the comparison on two objects of the C# IEqualityComparer Kullanımı type T.

Since IEqualityComparer is contravariant in the type T, you yaşama use the base class comparer with distinct if you specify the generic parameter to Distinct:

We’ll write a classic implementation of IEqualityComparer class. In our example, we need to compare customers. Two customers are distinct if your first char Name is different.

So what happens when it comes time to actually deduce the type argument? We have two candidates: Position and BaseClass. Both satisfy the stated bounds. Position satisfies the first bound because it is identical to the first bound, and satisfies the second bound because it is smaller than the second bound.

C# Mod Ittihaz İşlemi , yazgımız ile c sharp eğitimimize devam ediyoruz. Bu dersimizde Mod iktibas şu demek oluyor ki bölme meslekleminden mütebaki C# IEqualityComparer nerelerde kullanılıyor bulma kârlemini göreceğiz. Bu sermaye…

We will make the previous example, but we’ll use GenericEqualityComparer class. Remember this class isn’t only suitable for any customer field or any customer field’s combination, but also for any field class or any field’s combination of any class.

2 It affects other C# IEqualityComparer Temel Özellikleri ve Kullanımı places in a positive way, you generally want to implement it for a data class like this

However, choosing the more specific type Giraffe: return value dirilik implicitly be cast to a larger type Animal if needed; and a return type of IEnumerable implicitly casts to IEnumerable. C# IEqualityComparer nerelerde kullanılıyor And that's the most used variant interface. I wonder why the more general type was chosen?

5 When writing programs C# IEqualityComparer Kullanımı in C# with the help of LINQ I have come across the IEqualityComparer generic interface several times.
