how to get current console background and text colors?
提问by rsk82
I know how to set them (SetConsoleTextAttribute) but there isn't a GetConsoleTextAttribute to retrieve this information. On a unaffected console it should be int 7.
我知道如何设置它们 (SetConsoleTextAttribute) 但没有 GetConsoleTextAttribute 来检索此信息。在未受影响的控制台上，它应该是 int 7。
The problem is that when exiting from a program that sets the text color it stays the same for the time given window runs, and I cannot assume that user hasn't set the colors to his custom liking.
问题是，当退出设置文本颜色的程序时，它在给定窗口运行的时间内保持不变，我不能假设用户没有根据他的自定义喜好设置颜色。

A quick grep of wincon.hshows that CONSOLE_SCREEN_BUFFER_INFOhas a wAttributesmember which is documented as"The attributes of the characters written to a screen buffer by the WriteFile and WriteConsole functions, or echoed to a screen buffer by the ReadFile and ReadConsole functions." This matches the description of SetConsoleTextAttribute: "Sets the attributes of characters written to the console screen buffer by the WriteFile or WriteConsole function, or echoed by the ReadFile or ReadConsole function." The structure is returned by GetConsoleScreenBufferInfo.
一个快速的 grepwincon.h显示，其中CONSOLE_SCREEN_BUFFER_INFO有一个wAttributes成员被记录为“由 WriteFile 和 WriteConsole 函数写入屏幕缓冲区的字符属性，或由 ReadFile 和 ReadConsole 函数回显到屏幕缓冲区的字符属性。” 这符合以下描述SetConsoleTextAttribute：“设置由 WriteFile 或 WriteConsole 函数写入控制台屏幕缓冲区的字符的属性，或由 ReadFile 或 ReadConsole 函数回显的字符的属性。” 该结构由 返回GetConsoleScreenBufferInfo。

Thanks to Talent25 I made this function:
感谢 Talent25 我做了这个功能：
#include <Windows.h>
bool GetColor(short &ret){
CONSOLE_SCREEN_BUFFER_INFO info;
if (!GetConsoleScreenBufferInfo(GetStdHandle(STD_OUTPUT_HANDLE), &info))
return false;
ret = info.wAttributes;
return true;
}
using it:
使用它：
GetColor(CurrentColor);
CurrentColor - variable for output number of color (background * 16 + main color). Returned value informs if action was successful.
CurrentColor - 颜色输出数量的变量（背景 * 16 + 主色）。返回值通知操作是否成功。

Here is code snippet.
这是代码片段。
HANDLE m_hConsole;
WORD m_currentConsoleAttr;
CONSOLE_SCREEN_BUFFER_INFO csbi;
//retrieve and save the current attributes
m_hConsole=GetStdHandle(STD_OUTPUT_HANDLE);
if(GetConsoleScreenBufferInfo(m_hConsole, &csbi))
m_currentConsoleAttr = csbi.wAttributes;
//change the attribute to what you like
SetConsoleTextAttribute (
m_hConsole,
FOREGROUND_RED |
FOREGROUND_GREEN);
//set the ttribute to the original one
SetConsoleTextAttribute (
m_hConsole,
m_currentConsoleAttr);
