이 Color 구조체의 HSL(Hue-Saturation-Lightness) 채도 값을 가져옵니다.

Color의 채도입니다. 채도의 범위는 0.0부터 1.0까지이며, 여기서 0.0은 회색조이며 1.0은 가장 높은 채도입니다.

예제

다음 코드 예제는 Windows Forms 사용하도록 설계되었으며 이벤트 처리기의 Paint 매개 변수인 가 필요합니다.PaintEventArgse 코드는 다음 작업을 수행합니다.

• 비교에 사용할 구조redShade체의 Color instance 만듭니다.

• 열거형 요소를 반복 KnownColor 하여 과 같은 채도 redShade를 가진 알려진 모든 색을 찾습니다. 15개의 일치 항목이 발견되거나 루프 카운터의 값이 마지막 KnownColor 요소보다 크면 반복이 종료됩니다.

• 각 반복 중에 는 조건과 일치하는 경우 요소를 배열에 저장합니다 KnownColor .

• 브러시를 사용하여 사각형을 그립니다.

첫 번째 사각형은 로 표현되는 색으로 redShade그려집니다. 다른 각 사각형은 의 채도와 일치하는 을 redShade그립니다KnownColor.
