IsLowSurrogate(String, Int32)
문자열의 지정한 위치에 있는 Char 개체가 low surrogate인지 여부를 나타냅니다.
public:
static bool IsLowSurrogate(System::String ^ s, int index);
public static bool IsLowSurrogate (string s, int index);
static member IsLowSurrogate : string * int -> bool
Public Shared Function IsLowSurrogate (s As String, index As Integer) As Boolean
매개 변수
- s
- String
문자열
- index
- Int32
s
에서 평가할 문자의 위치입니다.
반환
s
매개 변수에 있는 지정한 문자의 숫자 값이 U+DC00부터 U+DFFF까지의 범위에 있으면 true
이고, 그렇지 않으면 false
.
예외
s
이(가) null
인 경우
index
가 s
내의 위치가 아닙니다.
설명
index
매개 변수는 0부터 시작 합니다.
Utf-16 인코딩은 16 비트 코드 포인트를 사용 하 여 단일 문자를 나타낼 뿐 아니라 서로게이트 쌍 이라고 하는 2 16 비트 코드 포인트를 사용 하 여 추상 문자를 나타낼 수 있도록 합니다. 이 쌍의 두 번째 요소는 하위 서로게이트입니다. 해당 코드 포인트의 범위는 U + D C 00 U + DFFF 까지입니다. 개별 서로게이트는 자체를 해석 하지 않습니다. 서로게이트 쌍의 일부로 사용 되는 경우에만 의미가 있습니다.
추가 정보
적용 대상
