C # Collection types

The job interview has encountered a problem:

Lists the collection types in C # ___;

Enumerates the concurrent collection types in C #;

I know not deep, find the answer, I hope you correct:

Collection types are common variants of data collections, such as hash tables, queues, stacks, dictionaries, and lists. The collection is based on the ICollection interface, the IList interface, the IDictionary interface, or the corresponding interface in its generic collection.

1. Array collection type: Describes an array function that allows an array to be treated as a collection.

2.ArrayList and List collection types: Describes the functionality of generic and non-generic lists (the most common collection types).

3.Hashtable and Dictionary collection types: Describes the functions of hash-based generics and non-generic dictionary types.

4.SortedList and SortedDictionary collection types: A dictionary that describes sorting and a mixed type of combination dictionaries and list features.

5. Queues Queue Collection type: Describes the functionality of generics and non-generic queues.

6. Stack Stack collection type: Describes the functionality of generics and non-generic stacks.

7.HashSet collection type: Describes the generic HashSet (T) collection type.

8.HashSet and LINQ Set operations: Describes set operations provided by the HashSet (T) collection type and LINQ set operations.

Concurrent collection types make multithreaded operations more secure, relative to the addition of lock locks to non-concurrent collections.

Several classes under the System.Collections.Concurrent

• Concurrentqueue
• Concurrentstack
• Concurrentbag: An unordered set of data structures that is useful when you don't need to consider order.
• BlockingCollection: Similar to the classic blocking queue data structure
• Concurrentdictionary
• Iproducerconsumer<t> and Blockingcollection<t>
