Using hexadecimal color code in System.Drawing.Color

Using hexadecimal color code in System.Drawing.Color

In C#, you can use a hexadecimal color code to create a System.Drawing.Color object using the ColorTranslator.FromHtml method. The FromHtml method takes a string representing the hexadecimal color code and returns a Color object.

Here's how you can use a hexadecimal color code to create a Color object:

using System; using System.Drawing; public class Program { public static void Main() { // Hexadecimal color code representation (e.g., "#RRGGBB") string hexColorCode = "#FFA500"; // Orange color // Convert the hexadecimal color code to a Color object Color color = ColorTranslator.FromHtml(hexColorCode); // Use the Color object as needed Console.WriteLine($"Red: {color.R}, Green: {color.G}, Blue: {color.B}"); } }

In this example, we use the hexadecimal color code "#FFA500" to represent the color orange. The ColorTranslator.FromHtml method converts this hexadecimal color code to a Color object. We then access the RGB components of the color using the R, G, and B properties of the Color object and print them to the console.

Keep in mind that the hexadecimal color code should be in the format "#RRGGBB," where "RR," "GG," and "BB" represent the red, green, and blue components of the color, respectively. Each component is a two-digit hexadecimal value ranging from 00 to FF (0 to 255 in decimal). The "#" symbol is optional and is often used to denote a hexadecimal color code.
