获取屏幕分辨率作为cmd中的变量 [英] Get screen resolution as a variable in cmd

问题描述

我需要一个脚本来复制特定图像，具体取决于所使用的屏幕分辨率. 到目前为止，我发现wmic desktopmonitor get screenheight给了我适当的输出，但是我在将其解析为可用变量时遇到了麻烦 问题是输出在三行上，我只需要第二行的信息即可.

I need a script to copy a specific image depending on the screen resolution being used. so far I've found that wmic desktopmonitor get screenheight is giving me the appropriate output but i'm having trouble parsing it to a useable variable the problem is that the output is on three lines and I only need the information from the second one.

任何人都可以帮忙吗?

推荐答案

您甚至可以通过单个wmic获取更多参数:

You can even get more parameters with one single wmic:

for /f %%i in ('wmic desktopmonitor get screenheight^,screenwidth /value ^| find "="') do set "%%f"
echo your screen is %screenwidth% * %screenheight% pixels

如果您需要拥有自己的变量名，则要复杂一些:

If you need to have your own variablenames, it's a bit more complicated:

for /f "tokens=1,2 delims==" %%i in ('wmic desktopmonitor get screenheight^,screenwidth /value ^| find "="') do (
  if "%%i"=="ScreenHeight" set height=%%j
  if "%%i"=="ScreenWidth" set width=%%j
)
echo your screen is %width% * %height% pixels

如果您只需要一个值:

for /f "tokens=2 delims==" %%i in ('wmic desktopmonitor get screenheight /value ^| find "="') do set height=%%i
echo %height%
