ConsoleColor Demo - 2 - C Sharp

ConsoleColor Demo - 2 (All foreground colors on all background colors in c#) . To check how text in any possible foreground ConsoleColor on any possible background ConsoleColor looks like I made a Console project in C Sharp. I also made basic requirement for the project as this: (A) Display line of text in all ConsoleColors in its default sequence using one line for one color. (B) Use navigation keys to change console background color in ConsoleColor default sequence, in any direction. (C) Provide mechanism for exiting from application. . Then I tried and made the above required project. Code for achieving above task is simple and is described as follows. (1) First all ConsoleColors are saved in an array in their default sequence. (2) Then a do-while loop starts. (3) In start of this loop console background color is set to first color in ConsoleColor array and console is cleared. (*) Application also displays useful information near top and bottom of screen on black bars. At top current background color is also displayed. Both info-bars are displayd from inside of do-while loop at different places. (4) Then in a for loop all alphabets in upper case then all digits then all alphabets in lower case are displayed  in all colors from ConsoleColor array, using one line for text in one color. (5) Then user input is taken and according to input: (5a) Console background color index is changed as follows: (*) Up-arrow, Backspace, Left-arrow, Page-Up, E, S, NumPad8, NumPad4 and NumPad9 keys are used for selecting previous  color in ConsoleColor array.  (*) Down-arrow, Spacebar, Right-arrow, Page-Down, D, F, NumPad2, NumPad6 and NumPad3 keys are used for selecting next color in ConsoleColor array. (*) Home and NumPad7 key is used for selecting first color in ConsoleColor array (*) End and NumPad1 key is used for selecting last color in ConsoleColor array. (5b) In step 2 started do-while loop either continues or Exit. X and Escape keys are used for exiting loop. (6) After loop exit application also ends after restoring defaults. . In the following table keys which can be used for performing different tasks are listed. Navigation Keys Action Keys Exit X Escape Next Color UpArrow PageUp LeftArrow Backspace E NumPad8 NumPad9 NumPad4 S Previous Color DownArrow PageDown RightArrow Spacebar D NumPad2 NumPad3 NumPad6 F First Color Home NumPad7 Last Color End NumPad1 . Exit is for exiting application. Remaining tasks are for selecting background console color. No matter 'Num Lok' key is on or off its buttons will work in same way for navigation. Following is the C# code of the project I described above. It is simple and easy to understand. Plus it is full of helpful comments throughout it. . .
