C#控制台程序还是很常用的, 尤其是开发Server程序的时候, 对于Server出现的各种提示信息使用不同颜色输出, 对用户将是一个很好的提示. 比如错误使用红色输出, 警告使用黄色输出, 而绿色则表示正常等等. 下面是我实现的一个简单的带颜色控制台类.

ColorConsole.cs:

    public enum Color
    {
        Black = 0x00000000,
        DarkBlue = 0x00000001,
        DarkGreen = 0x00000002,
        DarkCyan = 0x00000003,
        DarkRed = 0x00000004,
        DarkPink = 0x00000005,
        DarkYellow = 0x00000006,
        DarkWhite = 0x00000007,
        Gray = 0x00000008,
        Blue = 0x00000009,
        Green = 0x000000A,
        Cyan = 0x0000000B,
        Red = 0x0000000C,
        Pink = 0x0000000D,
        Yellow = 0x0000000E,
        White = 0x0000000F
    }

    class ColorConsole
    {
        private int hConsoleHandle;
        private COORD ConsoleOutputLocation;
        private CONSOLE_SCREEN_BUFFER_INFO ConsoleInfo;
        private int OriginalColors;

        private const int STD_OUTPUT_HANDLE = -11;

        [DllImport("kernel32.dll", EntryPoint = "GetStdHandle", SetLastError = true,
                        CharSet = CharSet.Auto,
                        CallingConvention = CallingConvention.StdCall)]
        private static extern int GetStdHandle(int nStdHandle);

        [DllImport("kernel32.dll", EntryPoint = "GetConsoleScreenBufferInfo",
                        SetLastError = true, CharSet = CharSet.Auto,
                        CallingConvention = CallingConvention.StdCall)]
        private static extern int GetConsoleScreenBufferInfo(int hConsoleOutput,
                         ref CONSOLE_SCREEN_BUFFER_INFO lpConsoleScreenBufferInfo);

        [DllImport("kernel32.dll", EntryPoint = "SetConsoleTextAttribute",
                        SetLastError = true, CharSet = CharSet.Auto,
                        CallingConvention = CallingConvention.StdCall)]
        private static extern int SetConsoleTextAttribute(int hConsoleOutput, int wAttributes);

        [StructLayout(LayoutKind.Sequential)]
        private struct COORD
        {
            short X;
            short Y;
        }

        [StructLayout(LayoutKind.Sequential)]
        private struct SMALL_RECT
        {
            short Left;
            short Top;
            short Right;
            short Bottom;
        }

        [StructLayout(LayoutKind.Sequential)]
        private struct CONSOLE_SCREEN_BUFFER_INFO
        {
            public COORD dwSize;
            public COORD dwCursorPosition;
            public int wAttributes;
            public SMALL_RECT srWindow;
            public COORD dwMaximumWindowSize;
        }

        // Constructor.
        public ColorConsole()
        {
            ConsoleInfo = new CONSOLE_SCREEN_BUFFER_INFO();
            ConsoleOutputLocation = new COORD();
            hConsoleHandle = GetStdHandle(STD_OUTPUT_HANDLE);
            GetConsoleScreenBufferInfo(hConsoleHandle, ref ConsoleInfo);
            OriginalColors = ConsoleInfo.wAttributes;
        }

        public void TextColor(Color color)
        {
            SetConsoleTextAttribute(hConsoleHandle, (int)color);
        }

        public void TextColor(Color textColor, Color backColor)
        {
            SetConsoleTextAttribute(hConsoleHandle, (int)textColor + (int)backColor * 16);
        }

        public void ResetColor()
        {
            SetConsoleTextAttribute(hConsoleHandle, OriginalColors);
        }
    }

TestCase:

    class Program
    {
        static void Main(string[] args)
        {
            ColorConsole cc = new ColorConsole();
            cc.TextColor(Color.Red, Color.Gray);
            Console.WriteLine("Server Stopped.");
        }
    }
