설명

는 PositiveTimeSpanValidator 개체가 TimeSpan 특정 조건을 충족하는지 확인하는 데 사용됩니다. CanValidate 메서드 유효성을 검사할 개체 형식에 필요한 형식과 일치 하는지 여부를 결정 합니다. 유효성 검사 중인 개체의 매개 변수로 전달 되는 Validate 메서드. 유효성 검사를 통과하려면 유효성을 검사하는 개체가 양수 TimeSpan 값이어야 합니다.

생성자

PositiveTimeSpanValidator()

PositiveTimeSpanValidator 클래스의 새 인스턴스를 초기화합니다.

메서드

CanValidate(Type)	개체 형식의 유효성을 검사할 수 있는지 여부를 확인합니다.
Equals(Object)	지정된 개체가 현재 개체와 같은지 확인합니다. (다음에서 상속됨 Object)
GetHashCode()	기본 해시 함수로 작동합니다. (다음에서 상속됨 Object)
GetType()	현재 인스턴스의 Type을 가져옵니다. (다음에서 상속됨 Object)
MemberwiseClone()	현재 Object의 단순 복사본을 만듭니다. (다음에서 상속됨 Object)
ToString()	현재 개체를 나타내는 문자열을 반환합니다. (다음에서 상속됨 Object)
Validate(Object)	개체의 값이 유효한지 여부를 확인합니다.
