Here, you'll find a first simple code sample that works only on simple types (the ones composed only by primitif properties), and a second one that is complete (for a wider range of classes and complex types).

Expose via static property — makes the comparer class private and generates a static property that exposes the comparer class to consumers.

IEqualityComparer is an interface which is used to find whether an object is equal or hamiş. 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).

The IEqualityComparer interface supports only equality comparisons. Customization of comparisons for sorting and ordering is provided by the IComparer interface.

If you change your class to implement IEquatable instead, the implementation of Distinct (which will use EqualityComparer.Default which in turn sees your type implements IEquatable and delegates to that) will work bey you expect.

Good news is that this same C# IEqualityComparer Kullanımı Distinct() method works for collections of our custom objects too. So if George Clooney accidentally creeps into our collection twice that's hamiş a sıkıntı:

What Distinct() actually does here is comparing object references. So our second George Clooney is in fact an independent object (since it was created independently) and its reference differs from the reference of the first one - therefore it appears in the output twice:

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