Creating SolidColorBrush from hex color value

Question

I want to create SolidColorBrush from Hex value such as #ffaacc. How can I do this?

On MSDN, I got :

SolidColorBrush mySolidColorBrush = new SolidColorBrush();
mySolidColorBrush.Color = Color.FromArgb(255, 0, 0, 255);

So I wrote (considering my method receives color as #ffaacc):

Color.FromRgb(
  Convert.ToInt32(color.Substring(1, 2), 16), 
  Convert.ToInt32(color.Substring(3, 2), 16), 
  Convert.ToInt32(color.Substring(5, 2), 16));

But this gave error as

The best overloaded method match for 'System.Windows.Media.Color.FromRgb(byte, byte, byte)' has some invalid arguments

Also 3 errors as: Cannot convert int to byte.

But then how MSDN example works?

So stupid that they don't allow the default #FFFFFF format. – MrFox Dec 18 '12 at 08:54 — MrFox, Dec 18 '12 at 08:54
None of these work for UWP – kayleeFrye_onDeck Aug 03 '19 at 03:27 — kayleeFrye_onDeck, Aug 03 '19 at 03:27

Try this instead:

(SolidColorBrush)new BrushConverter().ConvertFrom("#ffaacc");

I've been using:

new SolidColorBrush((Color)ColorConverter.ConvertFromString("#ffaacc"));

How to get Color from Hexadecimal color code using .NET?

This I think is what you are after, hope it answers your question.

To get your code to work use Convert.ToByte instead of Convert.ToInt...

string colour = "#ffaacc";

Color.FromRgb(
Convert.ToByte(colour.Substring(1,2),16),
Convert.ToByte(colour.Substring(3,2),16),
Convert.ToByte(colour.Substring(5,2),16));

using System.Windows.Media;

byte R = Convert.ToByte(color.Substring(1, 2), 16);
byte G = Convert.ToByte(color.Substring(3, 2), 16);
byte B = Convert.ToByte(color.Substring(5, 2), 16);
SolidColorBrush scb = new SolidColorBrush(Color.FromRgb(R, G, B));
//applying the brush to the background of the existing Button btn:
btn.Background = scb;

If you don't want to deal with the pain of the conversion every time simply create an extension method.

public static class Extensions
{
    public static SolidColorBrush ToBrush(this string HexColorString)
    {
        return (SolidColorBrush)(new BrushConverter().ConvertFrom(HexColorString));
    }    
}

Then use like this: BackColor = "#FFADD8E6".ToBrush()

Alternately if you could provide a method to do the same thing.

public SolidColorBrush BrushFromHex(string hexColorString)
{
    return (SolidColorBrush)(new BrushConverter().ConvertFrom(hexColorString));
}

BackColor = BrushFromHex("#FFADD8E6");
