示例1: ToArgbToStringExample1
public void ToArgbToStringExample1(PaintEventArgs e)
{
Graphics g = e.Graphics;
// Color structure used for temporary storage.
Color someColor = Color.FromArgb(0);
// Array to store KnownColor values that match the criteria.
KnownColor[] colorMatches = new KnownColor[167];
// Number of matches found.
int count = 0;
// Iterate through the KnownColor enums to find all corresponding colors
// that have a nonzero green component and zero-value red component and
// that are not system colors.
for (KnownColor enumValue = 0;
enumValue <= KnownColor.YellowGreen; enumValue++)
{
someColor = Color.FromKnownColor(enumValue);
if (someColor.G != 0 && someColor.R == 0 && !someColor.IsSystemColor)
colorMatches[count++] = enumValue;
}
SolidBrush myBrush1 = new SolidBrush(someColor);
Font myFont = new Font("Arial", 9);
int x = 40;
int y = 40;
// Iterate through the matches that were found and display each color that
// corresponds with the enum value in the array. also display the name of
// the KnownColor and the ARGB components.
for (int i = 0; i < count; i++)
{
// Display the color.
someColor = Color.FromKnownColor(colorMatches[i]);
myBrush1.Color = someColor;
g.FillRectangle(myBrush1, x, y, 50, 30);
// Display KnownColor name and the four component values. To display the
// component values: Use the ToArgb method to get the 32-bit ARGB value
// of someColor, which was created from a KnownColor. Then create a
// Color structure from the 32-bit ARGB value and set someColor equal to
// this new Color structure. Then use the ToString method to convert it to
// a string.
g.DrawString(someColor.ToString(), myFont, Brushes.Black, x + 55, y);
someColor = Color.FromArgb(someColor.ToArgb());
g.DrawString(someColor.ToString(), myFont, Brushes.Black, x + 55, y + 15);
