Re: Saving Colors to a db

Fabian,

What do you mean by 'using .NET serialization to store color values in a
database'?

There's another detail: When you reconstruct a color from its ARGB
value, the reconstructed Color is not equal to the original one any
longer.

E.g.:
Color one = Color.Red;
Color two = Color.Red;
Color three = Color.FromArgb (one.ToArgb);

one == two/one.Equals (two) => true
one == three/one.Equals (three) => false

This might bite you if you need to compare colors loaded from your
database to named colors. You can avoid it by either comparing the
ARGB values or by using .NET serialization to store Color values in a
database, as this should (I guess) include the Color names.
