C# How to I create a set of sets

Question

I want to create a set of sets (of int)

something like:

SortedSet<SortedSet<int>>

or

HashSet<HashSet<int>>

but when trying to match the sets it uses ReferenceEquals to compare

and thus is useless for my purpose

is there a way to make a set of sets useful in C#?

Answer 1

您需要将HashSet<int>.CreateSetComparer()传递给外部集以通过引用进行比较。
