示例1: colorMatches
Public Sub KnownColorBrightnessExample1(ByVal e As PaintEventArgs)
Dim g As Graphics = e.Graphics
' Color structures. One is used for temporary storage. The other
' is a constant used for comparisons.
Dim someColor As Color = Color.FromArgb(0)
Dim redShade As Color = Color.FromArgb(255, 200, 0, 100)
' Array to store KnownColor values that match the brightness of the
' redShade color.
Dim colorMatches(15) As KnownColor
' Number of matches found.
Dim count As Integer = 0
' iterate through the KnownColor enums until 15 matches are found.
Dim enumValue As KnownColor
For enumValue = 0 To KnownColor.YellowGreen
someColor = Color.FromKnownColor(enumValue)
If (someColor.GetBrightness()) = (redShade.GetBrightness()) Then
colorMatches(count) = enumValue

If count > 15 Then
Exit For

' Display the redShade color and its argb value.
