Converting from RGB ints to Hex

Question

What I have is R:255 G:181 B:178, and I am working in C# (for WP8, to be more specific)

I would like to convert this to a hex number to use as a color (to set the pixel

Answer 1

Using string interpolation, this can be written as:

$"{r:X2}{g:X2}{b:X2}"

Answer 2

Try the below:

using System.Drawing;
Color myColor = Color.FromArgb(255, 181, 178);
string hex = myColor.R.ToString("X2") + myColor.G.ToString("X2") + myColor.B.ToString("X2");

Answer 3

Greetings fellow humans,

//Red Value
int integerRedValue = 0;
//Green Value
int integerGreenValue = 0;
//Blue Value
int integerBlueValue  = 0;

string hexValue = integerRedValue.ToString("X2") + integerGreenValue.ToString("X2") + integerBlueValue.ToString("X2");

Answer 4

You can use ColorHelper library for this:

using ColorHelper;
RGB rgb = new RGB(100, 0, 100);
HEX hex = ColorConverter.RgbToHex(rgb);

Answer 5

You can use a shorter string format to avoid string concatenations.

string.Format("{0:X2}{1:X2}{2:X2}", r, g, b)
