C# Converting delphi TColor to color (Hex)

Question

These numbers are stored in the Database. They origionate from Delphi code. Al

Answer 1

It looks like the numbers are the base-10 representation of Delphi TColor values.

Delphi itself seems to provide some helper functions (e.g. GetRValue) to extract the respective read, green and blue values. You have to write something similar in c# yourself.

Having the values you can assemble them into a hex string.

string.Format("#{0:X2}{1:X2}{2:X2}", redComponent, greenComponent, blueComponent);

Simply converting the integer value to a hex-string, padded or not, will most likely not do the right thing.

UPDATE as commenter James L. points out, the order of the components is actually different for/in delphi. To generate a TColor-like value the order must be:

string.Format("#{0:X2}{1:X2}{2:X2}", blueComponent, greenComponent, redComponent);
