예제

다음 코드 예제에서는 로컬 컴퓨터에 특정 PerformanceCounterCategory 개체의 InstanceData 콘텐츠를 표시 합니다. 먼저 번호가 매겨진 범주 목록을 PerformanceCounter 표시합니다. 사용자가 범주 중 하나의 수를 입력하면 샘플은 의 각 PerformanceCounterPerformanceCounterCategoryPerformanceCounterinstance 연결된 instance 데이터를 표시합니다.

속성

InstanceName	이러한 인스턴스 데이터와 관련된 인스턴스 이름을 가져옵니다.
RawValue	성능 카운터 샘플과 관련된 원시 데이터 값을 가져옵니다.
Sample	이 데이터를 생성한 성능 카운터 샘플을 가져옵니다.

메서드

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)
