Is it possible to give an unambiguous definition to the concept of “information”? more hot questions

This way, you yaşama implement a test that fails if any properties are added. Of course, you'd have to add new properties to the array at the beginning. Birli using reflection is an expensive operation from a performance point of view, I'd propose to use it in the sınav, not in the comparer itself if you need to compare lots of objects.

Alternatively, you hayat write an empty comparer class that implements IEqualityComparer, and then pick the corresponding quick-fix from the Zir+Enter menu:

IEqualityComparer is an interface which is used to find whether an object is equal or not. We will see this in a sample where we have to find the distinct objects in a collection. This interface will implement the method Equals(T obj1,T obj2).

Your GetHashCode implementation always returns the same value. Distinct relies on a good hash function to work efficiently because it internally builds a hash table.

Most of the time a comparison could be implemented with some amount of linq. If it's one-off, the choice is probably just down to personal preference.

Implementing IEquatable only does a comparion between your object and C# IEqualityComparer Nasıl Kullanılır which is most likely to be the same type. This is performed frequently with the new methods brought in alongside LINQ in 3.5. Overriding Equals() from ValueType will do a check for any object type, and it’s recommended this is overridden with any custom value type alongside implementing IEquatable.

You could do this more elegantly using FluentAssertions C# IEqualityComparer nedir library. It has plenty assertion methods for collections.
