C# Color Table
This C# program generates a table containing HTML colors with names. It accesses KnownColors.Color table. Many HTML and system colors are available.
We can enumerate these in the C# language and the ASP.NET Framework. We build a table containing all named colors, making HTML easier to write.
Note: Here we see the HTML colors in a table generated using the C# language. Afterwards we see the code that wrote the table.

Example. We use the Enum.GetNames method and the typeof operator along with the Where extension method. With Where, we remove Control colors from the output. Other articles describe these methods in depth.
To compile the program, add the System.Drawing assembly to your project. When you execute it, all available colors will be printed to the Console. It uses the StartsWith method and LINQ extension methods.
C# program that generates HTML color table
using System;
using System.Drawing;
using System.Linq;
class Program
{
static void Main()
{
// Get enum strings and order them by name.
// Remove Control colors.
foreach (string c in Enum.GetNames(typeof(KnownColor)).Where(
item => !item.StartsWith("Control")).OrderBy(item => item))
{
// Write table row.
Console.WriteLine("<b style=background:{0}>{1}</b>",
c.ToLower(),
c.ToLower().PadRight(20));
}
}
}
Discussion. Sometimes we can create our documentation directly from the code and libraries we use. This is one example. The KnownColors can be enumerated and listed. This also helps us learn about how to use this programming language.
Summary. This table contains the KnownColors from the System.Drawing namespace. Next we saw the console program that generates the table. A color sheet can be useful for selecting named colors for Internet articles.
