Here's an example:

IStructuralComparable arayüzü, ekseriya Array ve Tuple kabilinden bilgi konstrüksiyonları aracılığıyla uygulanır. Bu veri örgüları, elemanlarının sıralamasını ve yapkaloriı dikkate alarak karşılaştırma yapar.

You generic method saf a type parameter T but the type is hamiş part of the signature of the function so how is T supposed to be used in the function? Anyway, you emanet use .Kemiksiz tuples or anonymous types to create hash codes by combining values but I am hamiş sure this answers your question.
