如何从系统属性获取 Windows 操作系统环境变量 [英] How to get Windows OS Environment Variable from System Property

问题描述

我遇到了一个关于系统属性环境变量的奇怪问题.

I am encountering a strange problem about System Property environment variable.

如你所知，我们可以打开Computer->Property->Advanced System Settings->Advanced->System Environment Variables->User Variables for admin

As you know, we can open Computer->Property->Advanced System Settings->Advanced->System Environment Variables->User Variables for admin

我将 Variable TEMP' 值更改为 C:\mytemp\ 并单击确定以保存它.

I change Variable TEMP' value to C:\mytemp\ and click OK to save it.

然而，在命令行中，当我回显 %TEMP% 时，它仍然显示原始路径，C:\Users\admin\AppData\Local\Temp.

However, In command line, when I echo %TEMP%, it still show original path, C:\Users\admin\AppData\Local\Temp.

当我在资源管理器中输入 %TEMP% 时，它会转到 C:\mytemp

When I input %TEMP% in explorer, it will go to C:\mytemp

现在我想要用户 API 来获取路径，GetEnvironmentVariable() 也将返回与命令行中的 echo %TEMP% 相同的路径.我怎样才能像exploer那样获得路径.提前致谢.

Now I want to user API to get the path, GetEnvironmentVariable() will also return path which is same as echo %TEMP% in command line. how can I get the path as exploer did. Thanks in advance.

附注.操作系统是Win7 x86

PS. OS is Win7 x86

推荐答案

通过计算机->属性->高级系统设置->高级->系统环境变量->用户变量更改环境路径会立即生效.但是请注意，那些正在运行的程序不会获得最新的环境变量.

Changing environment path through Computer->Property->Advanced System Settings->Advanced->System Environment Variables->User Variables will take effect immediately. However, please be noted that those programs which are running will not get the latest environment variable.

所以我认为你只是没有为 echo 重新打开一个新的 cmd.

So I thought that you simply didn't reopen a new cmd for echo.

打开一个新的cmd，再次echo，会显示新的路径.

Open a new cmd, and echo again, the new path will be shown.
