설명

CryptographicException 대체 오류 코드를 지정하지 않는 한 HRESULT CORSEC_E_CRYPTO 사용합니다.

CryptographicException인스턴스의 초기 속성 값 목록은 생성자를 참조하세요.

생성자

CryptographicException()	기본 속성을 사용하여 CryptographicException 클래스의 새 인스턴스를 초기화합니다.
CryptographicException(Int32)	지정된 HRESULT 오류 코드를 사용하여 CryptographicException 클래스의 새 인스턴스를 초기화합니다.
CryptographicException(SerializationInfo, StreamingContext)	사용되지 않음. 직렬화된 데이터를 사용하여 CryptographicException 클래스의 새 인스턴스를 초기화합니다.
CryptographicException(String)	지정된 오류 메시지를 사용하여 CryptographicException 클래스의 새 인스턴스를 초기화합니다.
CryptographicException(String, Exception)	지정된 오류 메시지와 이 예외의 원인인 내부 예외에 대한 참조를 사용하여 CryptographicException 클래스의 새 인스턴스를 초기화합니다.
CryptographicException(String, String)	지정된 형식의 지정된 오류 메시지를 사용하여 CryptographicException 클래스의 새 인스턴스를 초기화합니다.

속성

Data	예외에 대한 추가 사용자 정의 정보를 제공하는 키/값 쌍의 컬렉션을 가져옵니다. (다음에서 상속됨 Exception)
HelpLink	이 예외와 연결된 도움말 파일에 대한 링크를 가져오거나 설정합니다. (다음에서 상속됨 Exception)
HResult	특정 예외에 할당된 코딩된 숫자 값인 HRESULT를 가져오거나 설정합니다. (다음에서 상속됨 Exception)
InnerException	현재 예외를 발생시킨 Exception 인스턴스를 가져옵니다. (다음에서 상속됨 Exception)
Message	현재 예외를 설명하는 메시지를 가져옵니다. (다음에서 상속됨 Exception)
Source	오류를 발생시키는 애플리케이션 또는 개체의 이름을 가져오거나 설정합니다. (다음에서 상속됨 Exception)
StackTrace	호출 스택에서 직접 실행 프레임의 문자열 표현을 가져옵니다. (다음에서 상속됨 Exception)
TargetSite	현재 예외를 throw하는 메서드를 가져옵니다. (다음에서 상속됨 Exception)

메서드

Equals(Object)	지정된 개체가 현재 개체와 같은지 여부를 확인합니다. (다음에서 상속됨 Object)
GetBaseException()	파생 클래스에서 재정의되는 경우 하나 이상의 후속 예외의 근본 원인인 Exception 반환합니다. (다음에서 상속됨 Exception)
GetHashCode()	기본 해시 함수로 사용됩니다. (다음에서 상속됨 Object)
GetObjectData(SerializationInfo, StreamingContext)	사용되지 않음. 파생 클래스에서 재정의되는 경우 예외에 대한 정보를 사용하여 SerializationInfo 설정합니다. (다음에서 상속됨 Exception)
GetType()	현재 인스턴스의 런타임 형식을 가져옵니다. (다음에서 상속됨 Exception)
MemberwiseClone()	현재 Object단순 복사본을 만듭니다. (다음에서 상속됨 Object)
ToString()	현재 예외의 문자열 표현을 만들고 반환합니다. (다음에서 상속됨 Exception)

이벤트

SerializeObjectState

사용되지 않음. 예외에 대한 직렬화된 데이터를 포함하는 예외 상태 개체를 만들기 위해 예외가 serialize될 때 발생합니다. (다음에서 상속됨 Exception)
