Simpliest way to convert a Color as a string like #XXXXXX to System.Windows.Media.Brush

Question

I think that the title is clear !

What I have now is :

System.Drawing.Color uiui = System.Drawing.ColorTranslator.FromHtml(myString);
var intColor =          


        

Answer 1

You can use the System.Windows.Media.ColorConverter

var color = (Color)ColorConverter.ConvertFromString("#FF010203");
//OR
var color = (Color)ColorConverter.ConvertFromString("#010203");
//OR
var color = (Color)ColorConverter.ConvertFromString("Red");

//and then:
var brush = new SolidColorBrush(color);  

It's pretty flexible as to what it accepts. Have a look at the examples in XAML here. You can pass any of those string formats in.

Note: These are all in System.Windows.Media (for WPF) not to be confused with System.Drawing (for WinForms)

Answer 2

This is the helper class that I've used in the past

    public static Color HexStringToColor(string hexColor)
    {
        string hc = ExtractHexDigits(hexColor);
        if (hc.Length != 6)
        {
            // you can choose whether to throw an exception
            //throw new ArgumentException("hexColor is not exactly 6 digits.");
            return Color.Empty;
        }
        string r = hc.Substring(0, 2);
        string g = hc.Substring(2, 2);
        string b = hc.Substring(4, 2);
        Color color = Color.Empty;
        try
        {
            int ri = Int32.Parse(r, NumberStyles.HexNumber);
            int gi = Int32.Parse(g, NumberStyles.HexNumber);
            int bi = Int32.Parse(b, NumberStyles.HexNumber);
            color = Color.FromArgb(ri, gi, bi);
        }
        catch
        {
            // you can choose whether to throw an exception
            //throw new ArgumentException("Conversion failed.");
            return Color.Empty;
        }
        return color;
    }

and an additional helper class

        public static string ExtractHexDigits(string input)
        {
            // remove any characters that are not digits (like #)
            var isHexDigit
                = new Regex("[abcdefABCDEF\\d]+", RegexOptions.Compiled);
            string newnum = "";
            foreach (char c in input)
            {
                if (isHexDigit.IsMatch(c.ToString()))
                {
                    newnum += c.ToString();
                }
            }
            return newnum;
        }

Just use ColorTranslator method:

ColorTranslator.FromHtml("#010203");
