我搜索了SO,我可以找到很多从VBA运行PowerShell脚本的例子,但是我找不到任何运行简单命令的例子。
例如,这有效:
Dim retval As Variant
retval = Shell("PowerShell ""C:\MyScript.ps1""", vbNormalFocus)
但这不是:
Dim retval As Variant
Dim pscmd As String
pscmd = "PowerShell " & _
Chr(34) & "Get-ScheduledTask" & _
" -TaskName " & Chr(34) & "My Task" & Chr(34) & _
" -CimSession MYLAPTOP" & Chr(34)
retval = Shell(pscmd, vbNormalFocus)
Debug.Print pscmd
'pscmd = PowerShell "Get-ScheduledTask -TaskName "My Task" -CimSession MYLAPTOP"
我知道我可以将PS命令写入文件,将其作为脚本执行,然后删除该文件,但这似乎不是很优雅。

要运行内联Powershell命令,您可能需要使用IL_0000: nop
IL_0001: ldarg.0
IL_0002: ldfld int32 SyringeWpfTest.ILTesting::'<Counter>k__BackingField'
IL_0007: ldarg.1
IL_0008: ceq
IL_000a: ldc.i4.0
IL_000b: ceq
IL_000d: stloc.0
IL_000e: ldloc.0
IL_000f: brfalse.s IL_001a
IL_0011: nop
IL_0012: ldarg.0
IL_0013: ldarg.1
IL_0014: stfld int32 SyringeWpfTest.ILTesting::'<Counter>k__BackingField'
IL_0019: nop
IL_001a: ret
参数并用引号括起您的语句。如果在命令中使用单引号,也会更容易。
试试这个:
IL

Haven未经过测试,但执行政策可能是一个因素。
pscmd = "PowerShell -NoProfile -NoLogo -ExecutionPolicy Bypass -Command {" & _
Chr(34) & "Get-ScheduledTask" & _
" -TaskName " & Chr(34) & "My Task" & Chr(34) & _
" -CimSession MYLAPTOP" & Chr(34) & "}"
