Buffer.ByteLength(Array) 메서드

정의

지정된 배열의 바이트 수를 반환합니다.

public:
 static int ByteLength(Array ^ array);
public static int ByteLength (Array array);
static member ByteLength : Array -> int
Public Shared Function ByteLength (array As Array) As Integer

매개 변수

array
Array

배열입니다.

반환

Int32

배열의 바이트 수입니다.

예외

array이(가) null인 경우

array가 기본 형식이 아닌 경우

array가 2GB보다 큰 경우

예제

다음 코드 예제에서는 배열의 ByteLength 바이트 수를 반환 하는 메서드의 사용을 보여 줍니다.
