示例1: KnownColorBrightnessExample2
public void KnownColorBrightnessExample2(PaintEventArgs e)
{
Graphics g = e.Graphics;
// Color structures. One is a variable used for temporary storage. The other
// is a constant used for comparisons.
Color someColor = Color.FromArgb(0);
Color redShade = Color.FromArgb(255, 200, 0, 100);
// Array to store KnownColor values that match the brightness of the
// redShade color.
KnownColor[] colorMatches = new KnownColor[15];
// Number of matches found.
int count = 0;
// Iterate through the KnownColor enums until 15 matches are found.
for (KnownColor enumValue = 0;
enumValue <= KnownColor.YellowGreen && count < 15; enumValue++)
{
someColor = Color.FromKnownColor(enumValue);
if (someColor.GetBrightness() == redShade.GetBrightness())
colorMatches[count++] = enumValue;
}
// display the redShade color and its argb value.
SolidBrush myBrush1 = new SolidBrush(redShade);

// corresponds with the enum value in the array. also display the name of
// The KnownColor.
