因为我的电脑会取到两个分辨率的值，一个是实际的，下边一个是空的，所以在for过后，最终%screenwidth% %screenheight%得到的是空值，所以我测试 ...

不用两次读取：

@echo off

setlocal EnableDelayedExpansion

echo 当前分辨率为：

for /f %%i in ('"wmic desktopmonitor get screenwidth,screenheight /value"') do (

    set %%i>nul

  if not "!screenwidth!" == "" set 屏幕宽=!screenwidth!&&set 屏幕高=!screenheight!

)

echo %屏幕宽% %屏幕高%

pause>nul

测试了你的代码，获取不到。下面是我的运行结果：

D:\>setlocal EnableDelayedExpansion

D:\>echo 当前分辨率为：
当前分辨率为：

D:\>for /F %i in ('"wmic desktopmonitor get screenwidth,screenheight /value"') do (
set %i 1>nul
if not "!screenwidth!" == "" set 屏幕宽=!screenwidth! && set 屏幕高=!screenheight!
)

D:\>(
set
1>nul
if not "!screenwidth!" == "" set 屏幕宽=!screenwidth! && set 屏幕高=!screenheight!
)

D:\>(
set
1>nul
if not "!screenwidth!" == "" set 屏幕宽=!screenwidth! && set 屏幕高=!screenheight!
)

D:\>(
set ScreenHeight=768
1>nul
if not "!screenwidth!" == "" set 屏幕宽=!screenwidth! && set 屏幕高=!screenheight!
)

D:\>(
set ScreenWidth=1024
1>nul
if not "!screenwidth!" == "" set 屏幕宽=!screenwidth! && set 屏幕高=!screenheight!
)

D:\>(
set
1>nul
if not "!screenwidth!" == "" set 屏幕宽=!screenwidth! && set 屏幕高=!screenheight!
)

D:\>(

if not "!screenwidth!" == "" set 屏幕宽=!screenwidth! && set 屏幕高=!screenheight!
)

D:\>(
set ScreenHeight=
1>nul
if not "!screenwidth!" == "" set 屏幕宽=!screenwidth! && set 屏幕高=!screenheight!
)

D:\>(
set ScreenWidth=
1>nul
if not "!screenwidth!" == "" set 屏幕宽=!screenwidth! && set 屏幕高=!screenheight!
)

D:\>(
set
1>nul
if not "!screenwidth!" == "" set 屏幕宽=!screenwidth! && set 屏幕高=!screenheight!
)

D:\>(
set
1>nul
if not "!screenwidth!" == "" set 屏幕宽=!screenwidth! && set 屏幕高=!screenheight!
)

D:\>echo
ECHO 处于打开状态。

D:\>pause1>nul

当前分辨率为：

分析 Mof 文件: C:\WINDOWS\system32\wbem\Cli.mof(阶段错误 - 2)
计算机返回错误 0x8004402f
环境变量 Please 没有定义
ECHO 处于关闭状态。

Set objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\\.\root\cimv2")
Set colDesktops = objWMIService.InstancesOf("Win32_DesktopMonitor")

For Each objDesktop In colDesktops
WScript.Echo "桌面宽度：" & objDesktop.ScreenWidth
WScript.Echo "桌面高度：" & objDesktop.ScreenHeight
Next

都弄复杂了

1.vbs：

set oIE = CreateObject("htmlfile")

with oIE.parentWindow.screen

msgbox .width & "×" & .height

end with

先拿回去用用...

还有个疑问,就是:
为什么非要 echo off 呢? 否则就出现"ECHO 处于打开状态。"??
为什么呢?
