I'd also suggest small refactoring of FamilySelector class. Currently it holds the data and performs comparison. Usually implementation of IEqualityComparer is a veri-less class that just performs a comparison:
Enum’ı muhakkak yazdığımız projelerde kullanmışızdır. Data temelında bazı alanları öngörebiliriz.Bu alanlar mukannen bir değer kümesine sahiptir. Bunları bilgi analizindeki kategorik verilere benzetebiliriz ve alanların alabileceği bileğerler önceden belirlidir, sabittir ve vâsiletilebilir. Bu durum enum ile daha okunabilir kod yazmamızı ve bu dijital değerlerin ne anlama geldiğini anlamamızı olanak sağlamlar.
Bir dahaki sefere versiyon yapmış olduğumda kullanılmak üzere hamleı, elektronik posta adresimi ve web site adresimi bu tarayıcıevet kaydet.
Hope this article will help you to understand the IEqualityComparer interface. Don't hesitate to write questions or suggestions.
The second form is logical equality. Anyone who saf worked with databases understands the idea of identifiers and their use case for distinguishing sameness. Developers define reasons for equality in code, but the logic güç be composed of smaller precise equality comparisons.
The issue here is that comparing floating-point numbers for equality might derece work birli expected, due to minute rounding errors. There are different methods of comparing floating-point numbers for near-equality
According to the IEqualityComparer code example provided by microsoft, you will want to use the new keyword (so hiding the Equals implementation of the object) for implementing Equals.
In theory, there is only one sensible way of comparing C# IEqualityComparer Nasıl Kullanılır two instances of either type: They are equal if the X and Y properties in both instances are equal.
If we call a Distinct LinQ Extension Method, the result would be a new sequence with 7 elements, and we would hamiş find any distinct member.
Selamlar, bu makalemda C#’ da Enum’ı hatırlı nasıl kullanabilirizi ve kullanma metodoloji üzerinde C# IEqualityComparer Temel Özellikleri ve Kullanımı duracağım. Peşi sıra enumeration class’ı ile daha canlı enum kullanmaını göstereciğim.
Isn't it problematic to look at the data to decide to use a parametric vs. non-parametric sınav? more hot questions
(Making matters C# IEqualityComparer nerelerde kullanılıyor worse, there is a typo in the spec that says that "choose the more specific" is the right thing to do! This was the C# IEqualityComparer Kullanımı result of an editing error during the design process that has never been corrected. The compiler implements "choose the more general". I've reminded Mads C# IEqualityComparer Nasıl Kullanılır of the error and hopefully this will get fixed in the C# 5 spec.)
Doing that you changed the behavior for a single class, what if you need the same logic for other classes? If you need a "generic comparison". That is why you have IEqualityComparer.
