Also it is unclear why GetHashCode takes only value properties into account. Even though it will definitely work but looks a little bit strange. Maybe you should add a comment why class properties

The inclusion of your comparison class (or more specifically the AsEnumerable call you needed to use to get it to work) meant that the sorting logic went from being based on the database server to being on the database client (your application).

C# diline giriş gitmek yahut mevcut bilgilerini genişletmek isteyenler sinein yakınlarında kaynaklara esasvurmak yüce öneme sahiptir. İster temel seviye veri arayışında olun, icap müterakki kur konularda uzmanlaşmak isteyin, C# dili öğrenmek mebdevurabileceğin 10 temel menşe şunlardır:

Hash functions that are used to generate hash codes, actually do one thing: they project elements from some data kaş to a smaller data grup (the takım of hash codes). The former might be almost anything, while the latter is usually the set of integers.

Internal: Denetleme, ancak aynı derlemedeki sınıflar aracılığıyla erişilebilir hale hasılat. Bu durumda, muayeneün erişimi belirlenmişdır ve tek aynı derlemedeki gayrı sınıflar aracılığıyla erişilebilir.

Params anahtar kelime kullanımını gösteren mahdut bir program yapalım. Parametre olarak int tipinde bir dizi alacaktır.

I am trying to generate a listbox of items that is a concatenation of two strings. I have created a class that implements IEqualityComparer and I want to make this list distinct.

BaseClass satisfies the first bound because it is larger than the first bound, and identical to the second bound.

There are many cases where one might want to have a Dictionary locate objects using something other than 100% equivalence. Birli a simple example, one may wish to have a dictionary which matches in case-insensitive fashion. One way to accomplish that would be to convert strings to a canonical uppercase form before storing them in the dictionary or performing a lookup. An alternative approach is to supply the dictionary with an IEqualityComparer which will compute hash-codes and check for equality in some sort of C# IEqualityComparer nerelerde kullanılıyor case-independent function. There are some circumstances where converting strings to canonical form and using that form whenever possible will be more efficient, but there are others where it's more efficient to only store the string in its original form.

Basically, using override would mean that you will use your .Equals implementation regardless of whether you are an object or you are PropertySettings. If you use new when you are C# IEqualityComparer nedir an object you will use the base .

(Making matters worse, there is a typo in the spec that says C# IEqualityComparer nerelerde kullanılıyor that "choose the more specific" is the right thing to do! This was the result of an editing error during the design C# IEqualityComparer Nasıl Kullanılır process that başmaklık never been corrected. The compiler implements "choose the more general". I've reminded Mads of the error and hopefully this will get fixed in the C# 5 spec.)

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.
