Does the internal .NET HashSet implementation contain a method?

Question

I am writing a test for my library written in C #. And I want to check if two lists are the same if and only if they have the same elements (do not require elements in the same order). I am trying to convert a list to hashset and check if the two hashes are the same. But the result of the execution is not what I expected.

Can someone explain how the hashset method works? Does it match two objects using the getHashCode method of objects or the equals method? Thank!
