控制台命令C＃中的var

Question

How can I insert a var in console command? i mean somthing like that:

string color = Console.readline();
Console.ForegroundColor = ConsoleColor.color;

Answer 1

You are going to have to convert the string to a ConsoleColor. Like this:

using System;

class Program {
    static void Main(string[] args) {
        var colorName = Console.ReadLine();
        try {
            ConsoleColor color = (ConsoleColor)Enum.Parse(typeof(ConsoleColor), colorName, true);
            if (color == Console.BackgroundColor) throw new ArgumentException("That would make invisible output");
            Console.ForegroundColor = color;
            Console.WriteLine("Okay");
        }
        catch (ArgumentException ex) {
            Console.WriteLine(ex.Message);
        }
        Console.ReadLine();
    }
}

Not the greatest solution, the French won't understand why "Blanc" doesn't work.

Do you mean this:

string color = Console.ReadLine();
Console.ForegroundColor = (ConsoleColor) Enum.Parse(typeof(ConsoleColor), color);
