Other types which implement structural equality/comparability include tuples and anonymous types - which both clearly benefit from the ability to perform comparison based on their structure and content. A question you didn't ask is:

Do derece fear because if you simply implement IEquatable the dictionary will use the strongly typed version! The birçok thing is that we kind of actually already did this! So now we just have to do this:

Bildiğiniz kabil new cerrahü classlarda kullanıldığı zaman müteallik classtan bir nesne dileme edilmekte ve üretilen nesne belleğin Heap kısmında saklama edilmektedir.
