Color 메서드 또는 Color 메서드를 사용하여 미리 정의된 색으로 FromName(String)를 만들 경우 이 FromKnownColor(KnownColor)의 이름인 문자열을 반환하고, 그렇지 않으면 ARGB 구성 요소 이름과 그 값으로 구성된 문자열을 반환합니다.A string that is the name of this Color, if the Color is created from a predefined color by using either the FromName(String) method or the FromKnownColor(KnownColor) method; otherwise, a string that consists of the ARGB component names and their values.
예제
다음 코드 예제는 Windows Forms와 함께 사용 하도록 설계 되었으며 PaintEventArgs e 이벤트 처리기의 매개 변수인가 필요 합니다 Paint .The following code example is designed for use with Windows Forms, and it requires PaintEventArgs e, which is a parameter of the Paint event handler. 코드는 다음 작업을 수행합니다.The code performs the following actions:
KnownColor열거형 요소를 반복 하 여 0이 아닌 녹색 구성 요소와 영 (0) 빨강 구성 요소가 있고 시스템 색이 아닌 모든 알려진 색을 찾습니다.Iterates through the KnownColor enumeration elements to find all known colors that have a non-zero green component and a zero-value red component and that are not system colors.
반복 하는 동안는 KnownColor 배열에서 조건과 일치 하는 경우 요소를 저장 합니다.During each iteration, saves the KnownColor element - if it matches the criteria - in an array.
브러시를 사용 하 여 사각형을 그립니다.Uses a brush to paint rectangles. 각 사각형은 KnownColor 첫 번째 단계에 명시 된 조건과 일치 하는를 그립니다.Each of the rectangles is painted a KnownColor that matches the criteria stated in the first step. 의 이름과 KnownColor 해당 구성 요소 값도 표시 됩니다.The name of the KnownColor and its component values are also displayed.
이 예에서는 알려진 특정 색을 표시 하 고를 사용 하 여 ToString 색의 이름과 네 가지 구성 요소 값을 표시 합니다.This example displays certain known colors and uses ToString to display the names of the colors and their four component values.

설명
미리 정의 된 색을 알려진 색이 라고도 하며, 열거형의 요소로 표시 됩니다 KnownColor .A predefined color is also called a known color and is represented by an element of the KnownColor enumeration. 메서드를 ToString 사용 하 여 만든 구조에 메서드를 적용 하는 경우 Color FromArgb ToString argb 값이 미리 정의 된 색의 argb 값과 일치 하더라도는 argb 구성 요소 이름과 해당 값으로 구성 된 문자열을 반환 합니다.When the ToString method is applied to a Color structure that is created by using the FromArgb method, ToString returns a string that consists of the ARGB component names and their values, even if the ARGB value matches the ARGB value of a predefined color.
