Now, when we call Equals ourselves it will directly call our new fancy Equals that takes in a ScreenMetrics, which is great.

. The best example of this is arrays, which with .NET 4 now implement the IStructuralEquatable interface. 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:

IStructuralComparable arayüzü, çoğunlukla Array ve Tuple üzere bilgi örgüları tarafından uygulanır. Bu muta gestaltları, elemanlarının sıralamasını ve yapkaloriı dikkate alarak alınlaştırma yapar.

You generic method özgü a type parameter T but the type is not part of the signature of the function so how is T supposed to be used in the function? Anyway, you sevimli use .Kupkuru tuples or anonymous types to create hash codes by combining values but I am not sure this answers your question.
