C# 可以让用户输入设置控制台颜色吗？

Question

I created a simple console game and quite happy how it turned out so just making some final tweaks and i thought since I set the console colors for background and text, could I let the user chose the colors? I know it may be a can of worms, but now that I tried and it wont let me set the following, I at least want to know if this is possible. Here is what I tried.

Console.WriteLine("\nPlease enter desired background color for this screen: ");
var screen = Console.ReadLine();
Console.WriteLine("\nPlease enter desired text color for this screen: ");
var text = Console.ReadLine();
Console.BackgroundColor = ConsoleColor.screen;
Console.ForegroundColor = ConsoleColor.text;

The error VS gives is ConsoleColor does not contain a definition for screen and text.

Thanks to Hayden for getting me on the right track, came up with this:

     Console.WriteLine("\nPlease enter desired background color for this screen: ");
     string back = Console.ReadLine();
     Console.BackgroundColor = (ConsoleColor)Enum.Parse(typeof(ConsoleColor), back, true);

The reason that you're receiving the error is due to ConsoleColor.screen and ConsoleColor.text doesn't exist (which is not the same as screen and text ).

To achieve users wanting to change the console colour, you can try the following:

Console.WriteLine("\nPlease enter desired background color for this screen: ");
var screen = Console.ReadLine();
Console.WriteLine("\nPlease enter desired text color for this screen: ");
var text = Console.ReadLine();
// Attempt to parse the colors that the user entered into their respective enum values.
// The new values of background and foreground will be set to the user input
if(Enum.TryParse(screen, out ConsoleColor background))
{
    Console.BackgroundColor = background;
}
if (Enum.TryParse(text, out ConsoleColor foreground))
{
    Console.ForegroundColor = foreground;
}
