How to cast colordialog,color to a int (or long) ?

Call its .ToArgb() method.

I get an error:
Error 1 No overload for method 'ToArgb' takes '1' arguments

on the line:

Color kl = Color.ToArgb(BackColor);

What is wrong?

When I do not have an argument then he needs 1 argument.

Hi Rinaldo

You have mixed FromArgh with ToArgb

Color redColor = Color.FromName("Red");
int redValue = redColor.ToArgb();
Color newRedColor = Color.FromArgb(redValue);

If you are using CustomColors, be careful - IIRC it uses BGR, not
ARGB... so you may need to move the bytes around or parse manually:

Hi Morten,

I have:

Color kl = BackColor;
kleur = Color.ToArgb(kl);
binFavorietWriter.Write(kleur);

But does'nt work. I need to have the backcolor of the dialog to int and
write it to disk. (I ám a beginner)

Thanks.

And what doesn't work? I mean, I know the answer but really...you need to
get into the habit of reading and understanding the compiler errors. You
also need to post specific error messages when asking questions about
them, not just write "but doesn't work".

As for this specific problem, look more closely at Morten's code. Copy
and paste it into your application if you have to. There's a very
specific difference between what he wrote, and what you managed to type in
to your own code. It's a critical difference, and I'm sure the compiler
is doing a decent job explaining it to you.

Hi Morten,

Color kl = BackColor;
kleur = Color.ToArgb(kl);
binFavorietWriter.Write(kleur);

ToArgb() is not a static method so you can't use Color.ToArgb(), nor does it take a parameter so Color.ToArgb(kl) is wrong in two ways. You need to call ToArgb() on an instance of Color, and since kl is such an instance try kl.ToArgb()
