Is there a way to randomly get colors from a collection System.Windows.Media.Brushes or System.Windows.Media.Colors. I'm interested in getting a pair - (color name, color).

P.S. I know about the way to get a random color without a name.

C#

Random r = new Random();
Brush brush = new SolidColorBrush(Color.FromRgb((byte)r.Next(1, 255), (byte)r.Next(1, 255), (byte)r.Next(1, 233)));

If you want a random colour from a collection, then just generate a random index into the collection:

C#

int count = theCollection.Count;
Random r = new Random();
var randomValue = theCollection[r.Next(0, count)];
// You now have a random element from the collection

System.Windows.Media.Brushes is a standard collection and it does not support methods .Count and [r.Next(0, count)]. I do not know why. Perhaps I need to create my own collection with color names.

System.Windows.Media.Brushes is not a collection, i.e. it does not implement basic collection interfaces. In this case, you'd better create your own collection. A possible choice would be a Dictionary<string, Color> mapping the colour-name to its colour-value. Another possible choice would be a List<Tuple<string, Color>>.
