String.IsNormalized 메서드

정의

이 문자열의 형식이 특정 유니코드 정규화 형식인지를 나타냅니다.

오버로드

IsNormalized(NormalizationForm)

이 문자열의 형식이 지정한 유니코드 정규화 형식인지를 나타냅니다.

IsNormalized()

이 문자열의 형식이 유니코드 정규화 형식 C인지를 나타냅니다.

IsNormalized(NormalizationForm)

이 문자열의 형식이 지정한 유니코드 정규화 형식인지를 나타냅니다.

public:
 bool IsNormalized(System::Text::NormalizationForm normalizationForm);
public bool IsNormalized (System.Text.NormalizationForm normalizationForm);
member this.IsNormalized : System.Text.NormalizationForm -> bool
Public Function IsNormalized (normalizationForm As NormalizationForm) As Boolean

매개 변수

normalizationForm
NormalizationForm

유니코드 정규화 형식입니다.

반환

이 문자열의 형식이 true 매개 변수로 지정된 정규화 형식이면 normalizationForm이고, 그러지 않으면 false입니다.

예외

현재 인스턴스에 잘못된 유니코드 문자가 포함되어 있습니다.

설명

일부 유니코드 문자에는 결합 및/또는 복합 유니코드 문자 집합으로 구성된 여러 동일한 이진 표현이 있습니다. 단일 문자에 대한 여러 표현이 있으면 검색, 정렬, 일치 및 기타 작업이 복잡합니다.

유니코드 표준은 문자에 해당하는 이진 표현이 제공되면 하나의 이진 표현을 반환하는 정규화라는 프로세스를 정의합니다. 정규화는 다른 규칙을 준수하는 정규화 양식이라고 하는 여러 알고리즘을 사용하여 수행할 수 있습니다. .NET은 현재 C, D, KC 및 KD 정규화 형식을 지원합니다.

지원되는 유니코드 정규화 양식에 대한 설명은 을 참조하세요 System.Text.NormalizationForm.

호출자 참고

메서드는 IsNormalized 문자열에서 정규화되지 않은 첫 번째 문자가 발생하는 즉시 를 반환 false 합니다. 따라서 문자열에 정규화되지 않은 문자와 잘못된 유니코드 문자가 포함된 경우 메서드는 Normalize 를 throw하지만 IsNormalized 는 를 반환합니다falseArgumentException.
