I have a list of custom object where I am trying to remove duplicate records. I am seeing so many online articles which points towards IEqualityComparer(I've never used this before). Question is, when should I use it? I birey achieve same result by LINQ in one line code.
C# ile nominalm vüruttirirken, nesneleri temaşa eden sınıflar oluşturursunuz. Örneğin, bir otomobili oyun fail bir “Otomobil” dershaneı oluşturabilirsiniz. Bu sınıflardan nesneler oluşturarak programınızın temel yapı taşlarını inşa edersiniz.
You could possibly create a GenericComparer with a generic parameter which is constrained to be at least of base class which might get you closer to what you are trying to do. This would look like
I've assumed that you want to select ItemWrapper - it's hard to tell without C# IEqualityComparer nerelerde kullanılıyor seeing the types involved, but that looks likely to be what you want.

What Distinct() actually does here is comparing object references. So our second George Clooney is in fact an C# IEqualityComparer Nasıl Kullanılır independent object (since it was created independently) and its reference differs from the reference of the first one - therefore it appears in the output twice:
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 C# IEqualityComparer nedir for the general case.
