In Silverlight, the best way to convert between System.Drawing.Color and System.Windows.Media.Color?
I am trying to convert from System.Drawing.Color to Silverlight System.Windows.Media.Color. I am really trying to convey this color through the service.
System.Drawing.Color passed over the wire does not serialize the argb value independently.
I can convert argb value to 32bit int
[DataMember]
public int MyColor { get { return Color.Red.ToArgb(); } set {} }
But I don't see an appropriate method in the System.Windows.Media.Color method to convert it.
What's the best way to do this?
The 32-bit representation of System.Drawing.Color assumes a set of bytes (eg ARGB) and that each channel is 8-bit.
Silverlight doesn't make these assumptions. Instead, Media.Color is stored as four 32-bit floating point values, and the ordering is based on the color profile.
To create a Media.Color value from System.Drawing.Color, you must use the FromArgb / FromRgb methods and pass four separate components.
If necessary, you can AND-get these components from the components from the combined 32-bit value. You know (or can find out) the byte order of this color value, a knowledge that Silverlight does not have.

Thank. This is pretty much what I did, although I had to add a .ToHtml method to output it in hexadecimal notation:
[DataMember]
public string MyColor {
get {
return ColorTranslator.ToHtml(
Color.FromArgb(
Color.Red.A,
Color.Red.R,
Color.Red.G,
Color.Red.B
));
}
private set{}
}
So, on the other hand, I could use the code borrowed from here http://blogs.microsoft.co.il/blogs/alex_golesh/archive/2008/04/29/colorconverter-in-silverlight-2.aspx to convert six into a solid brush.
It works, but it is ugly and seems quite complicated for what I assumed, mistakenly, would obviously be the only method. Perhaps in the next release.
This is what Microsoft says to do - but I would not recommend it.
String xamlString = "<Canvas xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\" Background=\"MistyRose\"/>";
Canvas c = (Canvas) System.Windows.Markup.XamlReader.Load(xamlString);
SolidColorBrush mistyRoseBrush = (SolidColorBrush) c.Background;
Color mistyRose = mistyRoseBrush.Color;
Completely insane if you ask me, but this is from the MS docs!
