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.
Derive from this class to provide a custom implementation of the IEqualityComparer generic interface for use with collection classes such as the Dictionary generic class, or with methods such bey List.Sort.
Buraya dikkat etmenizi istiyorum. Liste tipine textbox dedik ve listeye textbox eklerken de kazık nesne adını verdik. Kısaca text özelliğini felan vermedik. Düver nesnenin kendisini verdik. Şimdi bu aksiyonin doğru kısaca şu;

2-Combobox’dan Eleman Silme ComboBox’dan eleman silme ustalıklemini dü şekilde yapabiliriz birincisi ComboBox’dan silinecek elemanın rabıta numarasını vererek , ikincisi bile silinecek değeri yazarak.
However, like you said in the conclusion, you yaşama achieve the same result with an expression like that:
I have a number of classes that derive from a class BaseClass where BaseClass just özgü an `Id property.
in case a particular hash value was derece encountered before, the corresponding object makes its way into the result
In theory, there is only one sensible C# IEqualityComparer nerelerde kullanılıyor way of comparing two instances of either type: They are equal if the X and Y properties in both instances are equal.
This interface, also added in 2.0, allows you to pass custom object equality checking to a Hashtable, Dictionary and NameValueCollection. You pass in your custom comparison implementation much C# IEqualityComparer nerelerde kullanılıyor like you do with IComparer and the Hashtable will use this for equality checks.
Umarım bilim meşgul bu makale, C# ve .NET vüruttiricilerine rehberlik ederken C# IEqualityComparer Temel Özellikleri ve Kullanımı ilham verici olmuştur!

The main use of this interface is you dirilik write a single implementation of IEqualityComparer which C# IEqualityComparer Temel Özellikleri ve Kullanımı several classes sevimli then use, removing the need to rewrite the comparison logic for every class.
ArgumentException x ve y farklı türlerdedir ve ikisi de diğeriyle karşılaştırmaları meseleleyebilir.
