Also We use ResetColor(), which is a method. Is resets all colors on the Console.
Result The 2 lines, when they are printed, will both have blue backgrounds and white foregrounds.
using System;
class Program
{
static void Main()
{
// Test colors with blue background, white foreground.
Console.BackgroundColor = ConsoleColor.Blue;
Console.ForegroundColor = ConsoleColor.White;
Console.WriteLine("White on blue.");
Console.WriteLine("Another line.");
Console.ResetColor();
}
}White on blue.
Another line.
Full lines. Writing an entire row of color in the Console may be helpful. It may make a good separator (like a line). Here we refactor the Console code into a separate method.
Tip In that method, you can change the colors, pad the string, and reset the console.
Detail For PadRight the parameter is the Console.WindowWidth minus one. This returns a string that will fill up the Console's width.
Also If you do not subtract one with the PadRight method, it sometimes incorrectly wraps lines.
using System;
class Program
{
static void Main()
{
// Write one green line.
WriteFullLine("This line is green.");
Console.WriteLine();
// ... Write another green line.
WriteFullLine("This line is also green.");
Console.WriteLine();
}
static void WriteFullLine(string value)
{
// Write an entire line to the console with the string.
Console.BackgroundColor = ConsoleColor.Green;
Console.ForegroundColor = ConsoleColor.DarkGreen;
Console.WriteLine(value.PadRight(Console.WindowWidth - 1));
// Reset the color.
Console.ResetColor();
}
}This line is green.
This line is also green.
All color enums. Here we see a program that displays all the backgrounds and foregrounds possible with the Console. It would be interesting to nest the loops and show all combinations.
Result The program will output a list of ConsoleColor values. White on blue may evoke memories of the BSOD (Blue Screen of Death).
using System;
class Program
{
static void Main()
{
// Demonstrate all colors and backgrounds.
Type type = typeof(ConsoleColor);
Console.ForegroundColor = ConsoleColor.White;
foreach (var name in Enum.GetNames(type))
{
Console.BackgroundColor = (ConsoleColor)Enum.Parse(type, name);
Console.WriteLine(name);
}
Console.BackgroundColor = ConsoleColor.Black;
foreach (var name in Enum.GetNames(type))
{
Console.ForegroundColor = (ConsoleColor)Enum.Parse(type, name);
Console.WriteLine(name);
}
}
}Black

Padding. Colors are not always the best formatting option. Try focusing on the structure of your output, with padding. We can make columns of text.
A summary. Colors, even on consoles, are beautiful. We used Console colors, including BackgroundColor and ForegroundColor. ResetColor and Console.WindowWidth are helpful.
