Color struct 包含所有 Web 颜色作为常量(系统颜色在 SystemColors 类中定义为常量)
要获取这些颜色的列表,只需执行以下操作:
var webColors = GetConstants(typeof(Color));
var sysColors = GetConstants(typeof(SystemColors));
将GetConstants 定义如下:
static List<Color> GetConstants(Type enumType)
{
MethodAttributes attributes = MethodAttributes.Static | MethodAttributes.Public;
PropertyInfo[] properties = enumType.GetProperties();
List<Color> list = new List<Color>();
for (int i = 0; i < properties.Length; i++)
{
PropertyInfo info = properties[i];
if (info.PropertyType == typeof(Color))
{
MethodInfo getMethod = info.GetGetMethod();
if ((getMethod != null) && ((getMethod.Attributes & attributes) == attributes))
{
object[] index = null;
list.Add((Color)info.GetValue(null, index));
}
}
}
return list;
}
编辑:
要像在 VS 中一样对颜色进行排序:
var webColors = GetConstants(typeof(Color));
var sysColors = GetConstants(typeof(SystemColors));
webColors.Sort(new StandardColorComparer());
sysColors.Sort(new SystemColorComparer());
StandardColorComparer 和 SystemColorComparer 定义如下:
class StandardColorComparer : IComparer<Color>
{
// Methods
public int Compare(Color color, Color color2)
{
if (color.A < color2.A)
{
return -1;
}
if (color.A > color2.A)
{
return 1;
}
if (color.GetHue() < color2.GetHue())
{
return -1;
}
if (color.GetHue() > color2.GetHue())
{
return 1;
}
if (color.GetSaturation() < color2.GetSaturation())
{
return -1;
}
if (color.GetSaturation() > color2.GetSaturation())
{
return 1;
}
if (color.GetBrightness() < color2.GetBrightness())
{
return -1;
}
if (color.GetBrightness() > color2.GetBrightness())
{
return 1;
}
return 0;
}
}
class SystemColorComparer : IComparer<Color>
{
// Methods
public int Compare(Color color, Color color2)
{
return string.Compare(color.Name, color2.Name, false, CultureInfo.InvariantCulture);
}
}
注意:
此代码已通过反射器从System.Drawing.Design.ColorEditor 获取。
