本文对比了C#与C++中各种集合类型的对应关系，包括Array、List<T>、Dictionary<TKey,TValue>等，并介绍了C#特有的线程安全集合。

Here's what I've found (ignoring the old non-generic collections):

Array - C array, though the .NET Array can have a non-zero starting index.
List<T> - std::vector<T>
Dictionary<TKey, TValue> - unordered_map<Key, Data>
HashSet<T> - unordered_set<Key>
SortedDictionary<TKey, TValue> - std::map<Key, Data>
SortedList<TKey, TValue> - equivalent to a std::vector<T> but keeping it ordered by using binary search + insert when adding elements.
SortedSet<T> - std::set<Key>
Queue<T> - std::queue<T>
Stack<T> - std::stack<T>
LinkedList<T> - std::list<T>

Notably missing from the .NET collections are the "multi-" variants, e.g., multiset, multimap, etc. However, they have added a number of very useful threadsafe collections: the "Concurrent-" variants, e.g., ConcurrentDictionary, ConcurrentQueue, etc.
