반환 값
FromName 메서드 또는 FromKnownColor 메서드를 사용하여 미리 정의된 색으로 Color를 만들 경우 이 Color의 이름인 문자열을 반환하고, 그렇지 않으면 ARGB 구성 요소 이름과 그 값으로 구성된 문자열을 반환합니다.
설명
미리 정의된 색은 이미 알려진 색이라고도 부르며, KnownColor 열거형의 요소로 나타냅니다. FromArgb 메서드를 사용하여 만든 Color 구조체에 ToString 메서드를 적용하면, ARGB 값이 미리 정의된 색의 ARGB 값과 일치하더라도 ToString은 ARGB 구성 요소 이름과 그 값으로 구성된 문자열을 반환합니다.
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. 각각의 다른 네모는 단계 1에 명시된 기준과 일치하는 KnownColor으로 그려집니다. KnownColor의 이름과 구성 요소 값도 표시됩니다.
이 예제에서는 몇 가지 이미 알려진 색을 표시하고, ToString을 사용하여 색의 이름과 네 개의 구성 요소 값을 표시합니다.
