是否可以在同一行中将控制台中的文本颜色和背景颜色更改为不同的颜色？C++

Question

我发现的一些解决方案似乎不适用于我的 Windows 终端。仅将整个行的文本更改为一种颜色。例子：

HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleTextAttribute(hConsole, 0 | 15);
cout << 1;

hConsole = GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleTextAttribute(hConsole,5 | 0);
cout << 2;

仅将文本和背景更改为一种颜色。谢谢你的帮助！

对的，这是可能的。它对您不起作用的原因是因为您的代码是错误的。你从不设置背景颜色；你只是操纵前景色。

问题的根源几乎可以肯定是您使用的是幻数 ( 0 | 15and 5 | 0) 而不是 中定义的常量<Windows.h>：

#define FOREGROUND_BLUE      0x0001 // text color contains blue.
#define FOREGROUND_GREEN     0x0002 // text color contains green.
#define FOREGROUND_RED       0x0004 // text color contains red.
#define FOREGROUND_INTENSITY 0x0008 // text color is intensified.
#define BACKGROUND_BLUE      0x0010 // background color contains blue.
#define BACKGROUND_GREEN     0x0020 // background color contains green.
#define BACKGROUND_RED       0x0040 // background color contains red.
#define BACKGROUND_INTENSITY 0x0080 // background color is intensified.

以下代码对我来说很好用：

const HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);

// yellow on blue
SetConsoleTextAttribute(hConsole, FOREGROUND_RED | FOREGROUND_GREEN | FOREGROUND_INTENSITY | BACKGROUND_BLUE);
std::cout << 1;

// blue on bright green
SetConsoleTextAttribute(hConsole, FOREGROUND_BLUE | BACKGROUND_GREEN | BACKGROUND_INTENSITY);
std::cout << 2;

// reset to black on white
SetConsoleTextAttribute(hConsole, FOREGROUND_RED | FOREGROUND_GREEN | FOREGROUND_BLUE | FOREGROUND_INTENSITY);
std::cout << std::endl;

这是我的控制台窗口的屏幕截图，以证明它有效。（但请注意，我的控制台颜色已针对 Tango 主题进行了自定义，因此您的控制台可能会使用略有不同的颜色。）

我建议通过定义一个枚举来让自己的生活更轻松：

enum ConsoleColors
{
   BlackFore   = 0,
   MaroonFore  = FOREGROUND_RED,
   GreenFore   = FOREGROUND_GREEN,
   NavyFore    = FOREGROUND_BLUE,
   TealFore    = FOREGROUND_GREEN | FOREGROUND_BLUE,
   OliveFore   = FOREGROUND_RED | FOREGROUND_GREEN,
   PurpleFore  = FOREGROUND_RED | FOREGROUND_BLUE,
   GrayFore    = FOREGROUND_RED | FOREGROUND_GREEN | FOREGROUND_BLUE,
   SilverFore  = FOREGROUND_INTENSITY,
   RedFore     = FOREGROUND_INTENSITY | FOREGROUND_RED,
   LimeFore    = FOREGROUND_INTENSITY | FOREGROUND_GREEN,
   BlueFore    = FOREGROUND_INTENSITY | FOREGROUND_BLUE,
   AquaFore    = FOREGROUND_INTENSITY | FOREGROUND_GREEN | FOREGROUND_BLUE,
   YellowFore  = FOREGROUND_INTENSITY | FOREGROUND_RED | FOREGROUND_GREEN,
   FuchsiaFore = FOREGROUND_INTENSITY | FOREGROUND_RED | FOREGROUND_BLUE,
   WhiteFore   = FOREGROUND_INTENSITY | FOREGROUND_RED | FOREGROUND_GREEN | FOREGROUND_BLUE,

   BlackBack   = 0,
   MaroonBack  = BACKGROUND_RED,
   GreenBack   = BACKGROUND_GREEN,
   NavyBack    = BACKGROUND_BLUE,
   TealBack    = BACKGROUND_GREEN | BACKGROUND_BLUE,
   OliveBack   = BACKGROUND_RED | BACKGROUND_GREEN,
   PurpleBack  = BACKGROUND_RED | BACKGROUND_BLUE,
   GrayBack    = BACKGROUND_RED | BACKGROUND_GREEN | BACKGROUND_BLUE,
   SilverBack  = BACKGROUND_INTENSITY,
   RedBack     = BACKGROUND_INTENSITY | BACKGROUND_RED,
   LimeBack    = BACKGROUND_INTENSITY | BACKGROUND_GREEN,
   BlueBack    = BACKGROUND_INTENSITY | BACKGROUND_BLUE,
   AquaBack    = BACKGROUND_INTENSITY | BACKGROUND_GREEN | BACKGROUND_BLUE,
   YellowBack  = BACKGROUND_INTENSITY | BACKGROUND_RED | BACKGROUND_GREEN,
   FuchsiaBack = BACKGROUND_INTENSITY | BACKGROUND_RED | BACKGROUND_BLUE,
   WhiteBack   = BACKGROUND_INTENSITY | BACKGROUND_RED | BACKGROUND_GREEN | BACKGROUND_BLUE,
};

然后像这样设置颜色：

SetConsoleTextAttribute(hConsole, ConsoleColors::BlackBack |
                                  ConsoleColors::RedFore));
