ArraySegment<T>(T[])

Source:

ArraySegment.cs

지정된 배열의 ArraySegment<T> 모든 요소를 구분하는 구조체의 새 인스턴스를 초기화합니다.

public:
 ArraySegment(cli::array <T> ^ array);

public ArraySegment(T[] array);

new ArraySegment<'T> : 'T[] -> ArraySegment<'T>

Public Sub New (array As T())

매개 변수

array

T[]

래핑할 배열입니다.

예외

ArgumentNullException

array은 null입니다.

설명

이 생성자는 의 ArraySegment<T> 모든 요소를 array구분하는 생성자를 만듭니다. 즉, Offset 속성은 ArraySegment<T> 0이고 해당 Count 속성의 길이 array는 0입니다. 배열의 ArraySegment<T> 일부만 구분하는 항목을 만들려면 생성자를 사용합니다 ArraySegment<T>(T[], Int32, Int32) .

원래 배열은 1차원이어야 하며 0부터 시작하는 인덱싱이 있어야 합니다.

여러 ArraySegment<T> 인스턴스는 동일한 원래 배열을 참조할 수 있으며 겹칠 수 있습니다.

ArraySegment<T>(T[], Int32, Int32)

Source:

ArraySegment.cs

지정된 배열에 있는 요소의 ArraySegment<T> 지정된 범위를 구분하는 구조체의 새 인스턴스를 초기화합니다.

public:

public ArraySegment(T[] array, int offset, int count);

new ArraySegment<'T> : 'T[] * int * int -> ArraySegment<'T>

Public Sub New (array As T(), offset As Integer, count As Integer)

매개 변수

array

T[]

구분할 요소의 범위를 포함하는 배열입니다.

offset

Int32

범위 내 첫 번째 요소의 인덱스(0부터 시작)입니다.

count

Int32

범위의 요소 수입니다.

예외

ArgumentNullException

array은 null입니다.

ArgumentOutOfRangeException

offset 또는 count 0보다 작습니다.

ArgumentException

offset 에서 count 유효한 범위를 array지정하지 않습니다.

원래 배열은 1차원이어야 하며 0부터 시작하는 인덱싱이 있어야 합니다.
