단순 형식
열거형 형식
구조체 형식
Nullable 값 형식
null을 허용하지 않는 형식을 T라고 한다면, 이에 대응되는 nullalbe형식 T?가 있다. string?은 string 또는 null값을 보유할 수 있는 형식이다.
튜블 값 형식
참조 형식
클래스 형식
string(UTF-16)
인터페이스 형식
배열 형식
대리자 형식(delegate)
delegate는 대표(자), 위임하다는 의미를 가지고 있다.
메서드에 대한 참조를 나타내는 형식이다. 함수 포인터와 달리 delegate는 객체지향적이며 형식이 안전하다.
System.Action 및 System.Func 는 대리자의 일반적인 정의를 제공한다. 대지라는 함수포인터와 유사하여 이벤트의 기반이 된다. 대리자는 메서드(명명된 것)나 무명 메서드와 연결하여 인스턴스화할 수 있다.
대리자는 메서드나 람다식을 사용하여 인스턴스화해야 한다.
한정자
internal
동일한 어셈블리의 파일 내에서만 액세스할 수 있습니다.
콜렉션
가변크기 컨테이너, Vector, ArrayList, LinkedList, HashSet, Stack, HashMap<key, value>
IEnumerable
foreach, 임의접근이 가능, 내부적으로 Enumerator를 가지고 있다.
IEnumerator
순차접근 가능(MoveNext()), 접근위치를 내부적으로 가지고 있다.
LINQ(Language Integrated Query)
var value = from 익명변수명 in ~
where ...
select 추출할_항목;
