Converting Hex Value to SolidColorBrush in Silverlight

I'm trying to write an IValueConverter in Silverlight. This IValueConverter will return a SolidColorBrush. The converter will be passed a hex value like "FFFF5300". Because Silverlight does not have the BrushConverter class, I needed to parse this value manually. In an attempt to do this, I have the following code:

byte a = (byte)(Convert.ToUInt32(color.Substring(0, 2), 16));
byte r = (byte)(Convert.ToUInt32(color.Substring(2, 2), 16));
byte g = (byte)(Convert.ToUInt32(color.Substring(4, 2), 16));
byte b = (byte)(Convert.ToUInt32(color.Substring(6, 2), 16));

My problem is, I can't use the Convert.ToX methods in an IValueConverter. Because of this, I'm not sure how to convert a two character string into a byte value. Can someone tell me how to do this?

Actually, you can use the Convert.ToXXX() methods in an IValueConverter. You just need to add the System namespace in front of Convert: System.Convert.ToXXX().

The value must be in the following format "#xxxxxxxx",

System.Drawing.ColorTranslator.FromHtml(Value);

I'm not sure if this what you're asking, but the following code doesn't use Convert:

byte a = byte.Parse(color.Substring(0, 2), NumberStyles.HexNumber);
// etc.
