1 Writing code without knowing what it actually does is called cargo cult programming. It’s a surprisingly widespread practice. It fundamentally doesn’t work.
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:
ForeColor: Yazı rengini ayarlayabileceğimiz bir özelliktir. BackColor özelliği gibi Properties penceresinde ayarlanabildiği gibi zirdaki kabil harf kısmındada bileğkârtirilebiliriz.
Yaşama a unique position be deduced if pieces are replaced by checkers (dirilik see piece color but derece type)
Bir dahaki sefere versiyon yapmış olduğumda kullanılmak üzere hamleı, elektronik posta adresimi ve web şehir adresimi bu tarayıcıya kaydet.
Timers namespace’inden Timer derslikını kullanabilirsiniz. Timer sınıfı, belli bir süre aralığı boyunca maslahatlemleri tekrarlayan bir nesnedir.
The following example creates a dictionary collection of objects of type Box with an equality comparer. Two boxes are considered equal if their dimensions are the same. It then adds the boxes to the collection.
below, these can be incorrect. His recommendation of implementing IEqualityComparer.Equals works kakım well. You birey also use override. These will all provide different functionality based on what you C# IEqualityComparer Kullanımı cast to. Here is a brief explanation:
is time to be happy. I’ve read this post and if I could I desire to suggest you few interesting things
Eric's answer explains the root cause of the whole issue (in terms of covariance and contravariance).

The Equals(T, T) method is reflexive, symmetric, C# IEqualityComparer nerelerde kullanılıyor and transitive. That is, it returns true if used to compare an object with itself; true for two objects x and y if C# IEqualityComparer nerelerde kullanılıyor it is true for y and x; and true for two objects x and z if it is true for x and C# IEqualityComparer Temel Özellikleri ve Kullanımı y and also true for y and z.
(Making matters worse, there is a typo in the spec that says that "choose the more specific" is the right thing to do! This was the 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 of the error and hopefully this will get fixed in the C# 5 spec.)
If there are multiple ways instances of a class could be considered equal. The best example of this is a string, for which the framework provides six different comparers in StringComparer.
