Convert string to Brushes/Brush color name in C#
I have a configuration file where a developer can specify a text color by passing in a string:
<text value="Hello, World" color="Red"/>
Rather than have a gigantic switch statement look for all of the possible colors, it'd be nice to just use the properties in the class System.Drawing.Brushes instead so internally I can say something like:
Brush color = Brushes.Black; // Default
// later on...
this.color = (Brush)Enum.Parse(typeof(Brush), prasedValue("color"));
Except that the values in Brush/Brushes aren't enums. So Enum.Parse gives me no joy. Suggestions?
Solution 1:
Recap of all previous answers, different ways to convert a string to a Color or Brush:
// best, using Color's static method
Color red1 = Color.FromName("Red");
// using a ColorConverter
TypeConverter tc1 = TypeDescriptor.GetConverter(typeof(Color)); // ..or..
TypeConverter tc2 = new ColorConverter();
Color red2 = (Color)tc.ConvertFromString("Red");
// using Reflection on Color or Brush
Color red3 = (Color)typeof(Color).GetProperty("Red").GetValue(null, null);
// in WPF you can use a BrushConverter
SolidColorBrush redBrush = (SolidColorBrush)new BrushConverter().ConvertFromString("Red");
Solution 2:
String to brush:
myTextBlock.Foreground = new BrushConverter().ConvertFromString("#FFFFFF") as SolidColorBrush;
That's my case here!
Solution 3:
A brush can be declared like this
Brush myBrush = new SolidBrush(Color.FromName("Red"));
Solution 4:
D'oh. After a while of looking I found:
Color.FromName(a.Value)
After hitting "post". From there it's a short step to:
color = new SolidBrush(Color.FromName(a.Value));
I'll leave this question here for others....
Solution 5:
You could use reflection for this:
Type t = typeof(Brushes);
Brush b = (Brush)t.GetProperty("Red").GetValue(null, null);
Of course, you'll want some error handling/range checking if the string is wrong.
