C++ Win32控制台颜色

Question

我知道如何在Win32 C++控制台中做颜色.但它效率不高.例如:

 SYSTEM("color 01")

在你的过程中减慢了很多.也:

 HANDLE h = GetStdHandle ( STD_OUTPUT_HANDLE );
 WORD wOldColorAttrs;
 CONSOLE_SCREEN_BUFFER_INFO csbiInfo;

 /*
  * First save the current color information
  */

 GetConsoleScreenBufferInfo(h, &csbiInfo);
 wOldColorAttrs = csbiInfo.wAttributes;

 /*
  * Set the new color information
  */

 SetConsoleTextAttribute ( h, FOREGROUND_RED );

效果很好,但颜色不多.此外,FOREGROUND_RED是深红色.

所以我想问的是,有没有像CLR属性Console::ForegroundColor集这样的方法,所以你可以使用ConsoleColor枚举中的任何颜色？

控制台只支持16种颜色,这些颜色是通过将四个值组合在一起创建的(我可能会把灰色/黑暗混淆,但你明白了):

namespace ConsoleForeground
{
  enum {
    BLACK             = 0,
    DARKBLUE          = FOREGROUND_BLUE,
    DARKGREEN         = FOREGROUND_GREEN,
    DARKCYAN          = FOREGROUND_GREEN | FOREGROUND_BLUE,
    DARKRED           = FOREGROUND_RED,
    DARKMAGENTA       = FOREGROUND_RED | FOREGROUND_BLUE,
    DARKYELLOW        = FOREGROUND_RED | FOREGROUND_GREEN,
    DARKGRAY          = FOREGROUND_RED | FOREGROUND_GREEN | FOREGROUND_BLUE,
    GRAY              = FOREGROUND_INTENSITY,
    BLUE              = FOREGROUND_INTENSITY | FOREGROUND_BLUE,
    GREEN             = FOREGROUND_INTENSITY | FOREGROUND_GREEN,
    CYAN              = FOREGROUND_INTENSITY | FOREGROUND_GREEN | FOREGROUND_BLUE,
    RED               = FOREGROUND_INTENSITY | FOREGROUND_RED,
    MAGENTA           = FOREGROUND_INTENSITY | FOREGROUND_RED | FOREGROUND_BLUE,
    YELLOW            = FOREGROUND_INTENSITY | FOREGROUND_RED | FOREGROUND_GREEN,
    WHITE             = FOREGROUND_INTENSITY | FOREGROUND_RED | FOREGROUND_GREEN | FOREGROUND_BLUE,
  };
}
