IEqualityComparer is a generic .Safi interface that allows implementing customized equality comparison for collections.
If the class is defined in such a way that you güç't define it kakım IEquatable. This would include classes defined by others and classes generated by the compiler (specifically anonymous types, which use a property-wise comparison by default).
Another scenario where it may be useful to have an alternative means of comparison is when an object holds a reference to an instance a mutable type, but will never expose that instance to anything that might mutate it. In general, two instances of int[] that hold the same sequence of values will derece be interchangeable, since it would be possible that in future one or both of them might be changed to hold different values.
IEqualityComparer is an interface which is used to find whether an object is equal or derece. 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).
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 C# IEqualityComparer Kullanımı must equal the value returned for y.
However, like you said in the conclusion, you güç achieve the same result with an expression like that:

Comparer name prefix — allows you to specify a prefix that will be used C# IEqualityComparer Temel Özellikleri ve Kullanımı in the name of the generated comparer class.
On the other hand, if there are several equally reasonable methods of comparing two Ts for equality, IEqualityComparer would seem more appropriate: This interface is hamiş meant to be implemented by T itself, but by other "external" classes.
Kakım a matter of style, we could encapsulate the equality comparer in our Player class and expose the IEqualityComparer through a static property.
