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.

If you want a generic solution that creates an IEqualityComparer for your class based on a property (which acts as a key) of that class have a look at this:

The same return value system applies as IComparer. The difference between this and IComparer is IComparable will be implemented on the class that contains your field values, while IComparable derived classes are used for custom sorting. So for example:

amma ben sadece otomatik olarak mavi ve 0 ın tekrarlanmamasını buttona basmış olduğumda kendiliğinden olarak silinsin isterim fareyle seçmek istemiyorum bunun bağırsakin bir kod varmıdır

Implementations are required to ensure that if the Equals(T, T) method returns true for two objects x and y, then the value returned by the GetHashCode(T) method for x must equal the value returned for y.

I would say that the best use would be when you need to plug in different equality rules for a certain algorithm. Much in the same way that a sorting algorithm might accept an IComparer, C# IEqualityComparer Nasıl Kullanılır a finding algorithm might accept an IEqualityComparer

The instructions C# IEqualityComparer Kullanımı and examples given here address the use of the feature in C#. For more information about other languages, refer to corresponding topics in the ReSharper by language section.

According to this C# IEqualityComparer nedir thinking, both types should implement IEquatable, because it doesn't seem likely that there are other meaningful ways of doing an equality sınav.

If the code is so hard to analyze that you have to write a backtracking algorithm to get it right, odds are good that the code should be written more clearly in the first place. If the compiler dirilik't make sense of it without backtracking, neither dirilik the human reader.

Equals/GetHashCode not only internalizes comparison logic, but also globalize them. There might be cases where I would like internal comparison (derece using collection) for just one time.
