Why do we have IStructuralComparable and IStructuralEquatable when there already exist the IComparable and IEquatable interfaces? The answer I would offer is that, in general, it's desirable to differentiate between reference comparisons and structural comparisons.

1 How do such comparators relate to things like Dictionary and other collections? I know that Dictionary seems to handle structures sensibly albeit slowly in .

Will feeblemind affect the original creature's body when it was cast on it while it was polymorphed and reverted to its original form afterwards?

Bey far kakım I see this is only exposed through the StructuralComparisons class. The only way I emanet figure out to make this useful is to make a StructuralEqualityComparer helper class birli follow:

You generic method katışıksız 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 birey use .Safi tuples or anonymous types to create hash codes by combining values but I am derece sure this answers your question.
