예제
다음 코드 예제에서는 형식을 사용하여 ConfigurationValidatorAttribute 두 개의 사용자 지정 유효성 검사기를 만드는 방법을 보여 줍니다. 첫 번째 예제에서는 하드 코딩된 매개 변수를 사용하여 유효성 검사를 수행합니다. 두 번째 예제에서는 관련 섹션 속성에 적용할 때 할당된 매개 변수를 사용하여 유효성 검사를 수행합니다. 이 코드 예제에는 세 개의 지원 파일도 포함되어 있습니다. 위에서 설명한 유효성 검사기를 사용 하는 사용자 지정 섹션을 포함 하는 첫 번째 파일, 두 번째 파일에는 사용자 지정 변환기 형식인 및 세 번째 파일을 만들고 사용자 지정 유효성 검사기 및 포함 된 섹션을 사용 하는 콘솔 애플리케이션을 포함 합니다.
다음 코드 예제에서는 하드 코딩된 매개 변수를 사용하여 고정 유효성 검사기를 만드는 방법을 보여줍니다.

설명
모든 ASP.NET 구성 표준 유효성 검사기 특성 형식은 .에서 ConfigurationValidatorAttribute파생됩니다. 이 형식을 사용하여 고유한 사용자 지정 유효성 검사기 특성을 만들 수 있습니다.
생성자
| ConfigurationValidatorAttribute() |
ConfigurationValidatorAttribute 클래스의 새 인스턴스를 초기화합니다. |
| ConfigurationValidatorAttribute(Type) |
지정된 유효성 검사기 형식을 사용하여 ConfigurationValidatorAttribute 클래스의 새 인스턴스를 초기화합니다. |
속성
| TypeId |
파생 클래스에서 구현된 경우 이 Attribute에 대한 고유 식별자를 가져옵니다. (다음에서 상속됨 Attribute) |
| ValidatorInstance |
유효성 검사기 특성 인스턴스를 가져옵니다. |
| ValidatorType |
유효성 검사기 특성의 형식을 가져옵니다. |
메서드
| Equals(Object) |
이 인스턴스가 지정된 개체와 같은지를 나타내는 값을 반환합니다. (다음에서 상속됨 Attribute) |
| GetHashCode() |
이 인스턴스의 해시 코드를 반환합니다. (다음에서 상속됨 Attribute) |
| GetType() |
현재 인스턴스의 Type을 가져옵니다. (다음에서 상속됨 Object) |
| IsDefaultAttribute() |
파생 클래스에서 재정의된 경우 이 인스턴스 값이 파생 클래스에 대한 기본값인지 여부를 표시합니다. (다음에서 상속됨 Attribute) |
| Match(Object) |
파생 클래스에서 재정의된 경우 이 인스턴스가 지정된 개체와 같은지 여부를 나타내는 값을 반환합니다. (다음에서 상속됨 Attribute) |
| MemberwiseClone() |
현재 Object의 단순 복사본을 만듭니다. (다음에서 상속됨 Object) |
| ToString() |
현재 개체를 나타내는 문자열을 반환합니다. (다음에서 상속됨 Object) |
명시적 인터페이스 구현
| _Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr) |
이름 집합을 해당하는 디스패치 식별자 집합에 매핑합니다. (다음에서 상속됨 Attribute) |
| _Attribute.GetTypeInfo(UInt32, UInt32, IntPtr) |
인터페이스의 형식 정보를 가져오는 데 사용할 수 있는 개체의 형식 정보를 검색합니다. (다음에서 상속됨 Attribute) |
| _Attribute.GetTypeInfoCount(UInt32) |
개체에서 제공하는 형식 정보 인터페이스의 수를 검색합니다(0 또는 1). (다음에서 상속됨 Attribute) |
| _Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr) |
개체에서 노출하는 메서드와 속성에 대한 액세스를 제공합니다. (다음에서 상속됨 Attribute) |
