在C＃中是否有等效的std :: set？

Question

I would like to have a container

StdStyleSet<A>

of

class A : IComparable<A> { ... }

which satisfies the properties of std::set. This would especially be:

• The elements themselve are the keys
• Automatically sorted on insertion

Answer 1

SortedSet<T> : see documents - although technically, it's in the .NET Framework.

For earlier versions, you could use a HashSet and sort using LINQ, not ideal if you're primarily consuming the set in an ordered fashion. Alternatively you could use a SortedDictionary<TKey,TValue> with the value as Object and store your elements in the keys with nulls for the values.
