Tupler, birden bir küme değeri sessiz bir örgüda saklamak muhtevain kullanılan data gestaltlarıdır. StructuralComparisons klası, tuplerin elemanlarını karşılaştırarak, strüktürel olarak denktaş olup olmadıklarını belirlemek yürekin kullanılabilir.

This makes it possible to distinguish whether you are comparing two arrays for reference equality, or for "structural equality" - whether they have the same number of items with the same values in each position. Here's an example:
As far as I see this is only exposed through the StructuralComparisons class. The only way I sevimli figure out to make this useful is to make a StructuralEqualityComparer helper class kakım follow:
