单行 C# 控制台中的多色字符

Question

如何仅使用基本命令（例如Console.Write和Console.WriteLine）在一行中打印多色字符？例如，我需要这样的东西：

Console.WriteLine($"red{M}green{U}blue{L}yellow{T}purple{I}");

其中M、U和L是不同的值，如int或string。

Answer 1

您可以使用字典，如下面的代码所示，然后使用循环：

Dictionary<int, KeyValuePair<string, ConsoleColor>> keyValuePairs = new Dictionary<int, KeyValuePair<string, ConsoleColor>>();
keyValuePairs.Add(1, new KeyValuePair<string, ConsoleColor>("my blue text", ConsoleColor.Blue));
keyValuePairs.Add(2, new KeyValuePair<string, ConsoleColor>("my red text", ConsoleColor.Red));

foreach (var keyItem in keyValuePairs.Keys)
        {
            ConsoleColor color = keyValuePairs[keyItem].Value;
            string textTobeDisplayed = keyValuePairs[keyItem].Key;
            Console.ForegroundColor = color;
            Console.Write(textTobeDisplayed);
        }

这就是我会使用的，可能不是最好的方法，但它确实有效。

class Program
{
    static void Main(string[] args)
    {
        // ~ red, ` green, ^ blue, * yellow, _ purple
        ColorWrite("~M`u^l*t_i", true);
        ColorWrite("~This is red,^ yet this is blue.", true);
        ColorWrite("~Mul`ti^ple ", false);
        ColorWrite("*Col_ours ", false);
    }
    // variable contains both consoleColor and char
    struct ColourKey
    {
        public ConsoleColor color;
        public char key;
        public ColourKey(ConsoleColor Color, char Key)
        {
            this.color = Color;
            this.key = Key;
        }
    }
    static void ColorWrite(string rawtext, bool endline)
    {
        //all avaliable colours, for more just make the array bigger
        ColourKey[] Pallete = new ColourKey[5];
        Pallete[0] = new ColourKey(ConsoleColor.Red, '~');
        Pallete[1] = new ColourKey(ConsoleColor.Green, '`');
        Pallete[2] = new ColourKey(ConsoleColor.Blue, '^');
        Pallete[3] = new ColourKey(ConsoleColor.Yellow, '*');
        Pallete[4] = new ColourKey(ConsoleColor.DarkMagenta, '_'); //ConsoleColor does not contain purple
        foreach (char c in rawtext)
        {
            bool CanWrite = true;
            foreach (ColourKey ck in Pallete)
            {
                if (c == ck.key)
                {
                    Console.ForegroundColor = ck.color;
                    CanWrite = false;
                }
            }
            if (CanWrite)
            {
                Console.Write(c);
            }
        }
        Console.ResetColor();
        // true function works like writeline(), false works like write()
        if (endline)
        {
            Console.WriteLine();
        }
        
    }

我希望这对您有所帮助

class Program
{
    static void Main(string[] args)
    {
        Console.ForegroundColor = ConsoleColor.Blue;
        Console.Write("White on Blue.");
        Console.ForegroundColor = ConsoleColor.Red;
        Console.Write("White on Red.");
        Console.ResetColor();
        Console.ReadLine();
    }
}
