Install Theory and .NET

Question

Recently, I came across a situation where set theory and mathematics corresponded to what I did with writing (provided that there is an easier way to accomplish what I need, i.e. LINQ), but I did not think about it at that time). However, I was not aware of any common library sets. Provided by IEnumerables provide some specified operations (Union, etc.), but do not look like intersection or comparison. Can anyone point out what fits here? Something that implements math using a generic type?

Answer 1

In the structure (3.5+), there is a HashSet<T> that does what you need..NET 4 also introduced SortedSet<T> and the common interface ISet<T> .

Answer 2

System.Collections.Generic.HashSet has a number of predefined operations, including Subset, Superset, Intersection, Union, etc.
