Hi!

Strange idea, to say the least. Why?

Solution 1

Hash codes only identify uniqueness in an object instance, they are not meant to reconstruct the object from its hash code.

You should be using the Color.FromArgb and Color.ToArgb to get the values you need. You can't reconstruct the color from the color's hash code.

[Edit]

Here is a great discussion[^] on the use of hash codes.

Also read MSDN documentation[^] on the do's and don'ts of working with hash codes.

Solution 2

Every heard of such thing as informatics? :-)

When you take a hash code from some object, you generally loose some information. Does it tell you something?

(Please see the my comment to the question.)
