반환 값
Color의 32비트 ARGB 값입니다.
설명
32비트 ARGB 값의 바이트 순서는 AARRGGBB입니다. AA로 표시되는 가장 중요한 바이트(MSB)는 알파 구성 요소 값입니다. RR, GG 및 BB로 표시되는 둘째, 셋째 및 넷째 바이트는 각각 빨강, 녹색 및 파랑의 색 구성 요소입니다.
예제
다음 코드 예제는 Windows Forms에 적용되며, 여기에는 Paint 이벤트 처리기의 매개 변수인 PaintEventArgse가 필요합니다. 이 코드는 다음 작업을 수행합니다.
녹색 구성 요소 값이 0이 아니고 빨강 구성 요소 값이 0이며 시스템 색이 아닌 이미 알려진 모든 색을 찾기 위해 KnownColor 열거형 요소 전체를 반복합니다.
반복할 때마다 KnownColor 요소가 기준과 일치하면 이 요소를 배열에 저장합니다.
네모를 그리는 데 브러시를 사용합니다.
각 사각형은 첫째 글머리 기호에 명시된 기준과 일치하는 KnownColor로 그려집니다. KnownColor의 이름과 구성 요소 값도 표시됩니다.
이 예제에서는 몇 가지 이미 알려진 색, 색의 이름과 네 개의 구성 요소 값을 표시합니다. ToArgb 메서드는 구성 요소 값을 표시하기 위한 예비 단계로 사용됩니다.
