If you do decide you need a comparer, you birey certainly use a generalized comparer (see DMenT's answer), but if you need to reuse that logic you should encapsulate it in a dedicated class. You could even declare it by inheriting from the generic base:

When you find yourself really to need this because you have to many properties you probably have some basic sorun bey your class is doing too much.

Yaşama a unique position be deduced if pieces are replaced by checkers (kişi see piece color but not type)

 

Your GetHashCode implementation always returns the same value. Distinct relies on a good hash function to work efficiently because it internally builds a hash table.

Photo by Moosa Haleem Equality might seem straightforward, but it tends to get fuzzier the longer you think about it. When it comes to programming, there are two general thoughts around equality.

However you should have some good pre-checks within GetHashCode to avoid unneccessary calls to this slow method.

below, these gönül be incorrect. His recommendation of implementing IEqualityComparer.Equals works bey well. You güç also use override. These will all provide different functionality based on what you cast to. Here is a brief explanation:

Unity kadar pop künde motorları C# desteği sunar. Bu sayede C# bilgisiyle 2D yahut üç boyutlu oyunlar geliştirebilirsin.

This interface, also added in 2.0, allows you to pass custom object equality checking to a Hashtable, Dictionary and C# IEqualityComparer nerelerde kullanılıyor NameValueCollection. You pass in your custom comparison implementation much like you do with IComparer and the Hashtable will use this for equality checks.

Birli we dirilik see, to satisfy the interface, we need to implement two methods: Equals and GetHashCode. Additionally, we need to take note that this interface is a contravariant interface.

In this post, we’ll see how we sevimli implement the IEqualityComparer interface in C# and how it kişi help us C# IEqualityComparer Temel Özellikleri ve Kullanımı define logical comparisons. Additionally, we’ll see how we güç use our implementation in code.

And yes, after this the output of the program doesn't change at all. So, what the hell is LINQ doing and why doesn't C# IEqualityComparer Nasıl Kullanılır it even try to use the equality comparer that we have provided? The situation was even bitter for me because I was trying to use Distinct() combined with custom C# IEqualityComparer Nasıl Kullanılır equality comparer to prepare data for pushing to veri base, so I ended up with SQL Server telling me that I am breaking a primary key constraint. Because of being focused on a broader problem C# IEqualityComparer Kullanımı I didn't take time to think over the stuff that I was trying to use. What I missed was the fact that LINQ, being a query engine, tries to perform kakım efficiently bey possible.

PS. I don't think any custom Equals methods work with entity framework directly on the database side (I think you know this because you do AsEnumerable) but this is a much simpler method to do a simple Equals for the general case.
