Converting RGB to Hexadecimal in C#:

Let's write a C# program to convert RGB values to hexadecimal as shown below,

using System;

class Program
{
    static void Main(string[] args)
    {
        int red = 120;
        int green = 200;
        int blue = 255;

        string hexColor = RGBToHex(red, green, blue);

        Console.WriteLine("RGB: ({0}, {1}, {2}) converts to Hexadecimal: {3}", red, green, blue, hexColor);
    }

    static string RGBToHex(int red, int green, int blue)
    {
        return String.Format("#{0:X2}{1:X2}{2:X2}", red, green, blue);
    }
}

Output:

RGB: (120, 200, 255) converts to Hexadecimal: #78C8FF
