Console pattern (2)-custom text display color

Section 2: custom text display color the text preset displayed on the console is black and white, although you can use the color command to change the background color and foreground color of the entire console, however, what we study here is that in the same Console window, the program can input texts of different colors according to different requirements. A colorful Console window will be very attractive to users. if the text in the console is not set to color, you need to call the system API setconsoletextattribute function. The following code is available on the Internet. I have tested it and I will post it for your reference: // lelecolour. CS
Using system;
// Need this to make API CILS
Using system. runtime. interopservices;
Using pfitzsimons. consolecolour;
