Burada enum kümesinde sıfır bir elemana erişmek isteriz. Runtime da hiç bir mesele gayrimümkün ve bizlere dijital kıymeti yahut olması gereken numerik değeri döner , yanlış olduğunun farkına varmayız. Yine de yoklama etmekte kâr var :)

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

This is it. We have explored the interaction between LINQ extension methods and custom IEqualityComparers and even implemented one. The resulting class is both easy to use and highly customizable, because its operation is fully defined by the key selector function provided by user.

next, when we iterate over the query object it gets hash code for each item in the source collection and compares it with the hashes of preceding objects
