I'm trying to dynamically set a button background color from Hex in Windows Phone 7.

    SolidColorBrush myBrush = new SolidColorBrush();
    myBrush.Color = ColorTranslator.FromHtml("#123456");
    pbMood.Background = myBrush;

ColorTranslator seems to not be available. That line gives a compiler error that it isn't found.

Am I looking in the wrong place (a different namespace?), or is there another way to do this from code?

回答1:

This class is not available in Silverlight.

Instead, you can write it yourself.

public static SolidColorBrush GetColorFromHexa(string hexaColor)
{
    return new SolidColorBrush(
        Color.FromArgb(
            Convert.ToByte(hexaColor.Substring(1, 2), 16),
            Convert.ToByte(hexaColor.Substring(3, 2), 16),
            Convert.ToByte(hexaColor.Substring(5, 2), 16),
            Convert.ToByte(hexaColor.Substring(7, 2), 16)
        )
    );
}

This StackOverflow answer gives an even simpler way to use hex values to create a SolidColorBrush.

Brush brush = new SolidColorBrush(new Color() { R = 0xFF, G = 0xA6, B = 0x10});
