How to get the hex color code from a color dialog in visual studio?

Question

I have a color dialog in visual studio, I am currently using this c# code to display the color dialog and set the color to a panel:

private void ColorButton_Click(object sender, EventArgs e)
{
    if (colorDialog1.ShowDialog() == DialogResult.OK)
    {
        ColorPanel.BackColor = colorDialog1.Color;
    }
}

How could I set a label to the hexadecimal color code of the color picker?

Beat me to it by 1 second... – Thorsten Dittmar Jul 04 '16 at 12:53 — Thorsten Dittmar, Jul 04 '16 at 12:53

You can try this

Get ARGB (Alpha, Red, Green, Blue) representation for the color
Filter out Alpha channel: & 0x00FFFFFF
Format out the value as hexadecimal ("X6")

Implementation

  String code = (colorDialog1.Color.ToArgb() & 0x00FFFFFF).ToString("X6");

Edit: if you want to get Color back from code, try FromArgb:

  string code = "FFDDAA";

  Color color = Color.FromArgb(Convert.ToInt32(code, 16));

Anyone know how to reverse this? To go from HEX to Color? – Mark Aug 22 '18 at 14:51

@Mark: try `Color.FromArgb` and `Convert.ToInt32` (see my edit) – Dmitry Bychenko Aug 22 '18 at 18:33
@DmitryBychenko Couldn't get that to work. `System.Drawing.ColorTranslator.FromHtml("#000000");` was what I ended up using. – Mark Aug 23 '18 at 13:57
