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?

Answer 1

You can try this

1. Get ARGB (Alpha, Red, Green, Blue) representation for the color
2. Filter out Alpha channel: & 0x00FFFFFF
3. 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));
