如何在C#控制台程序中对输出文本使用颜色

· 技术 · 2 分钟阅读

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;

    private static extern int GetStdHandle(int nStdHandle);

    private static extern int GetConsoleScreenBufferInfo(int hConsoleOutput,
                     ref CONSOLE_SCREEN_BUFFER_INFO lpConsoleScreenBufferInfo);

    private static extern int SetConsoleTextAttribute(int hConsoleOutput, int wAttributes);

    private struct COORD
    {
        short X;
        short Y;
    }

    private struct SMALL_RECT
    {
        short Left;
        short Top;
        short Right;
        short Bottom;
    }

    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.");
    }
}
