String cmdlet中的函数名

我尝试在set-acl cmdlet中使用我的函数，但它确实工作正常，我的函数被识别为一个简单的“字符串”

它被识别为字符串，因为您将其作为字符串编写。引号（“or”）中的所有内容都是字符串

如果函数返回字符串值，则可以如下使用：

$acl = Get-Acl C:\MSI -Verbose
$acl.SetAccessRuleProtection($True, $False) 
$rule = New-Object System.Security.AccessControl.FileSystemAccessRule ("Get-GroupName -SID 'S-1-1-0'","FullControl", "ContainerInherit, ObjectInherit", "None", "Allow") -Verbose 
$acl.AddAccessRule($rule) 
$rule = New-ObjectSystem.Security.AccessControl.FileSystemAccessRule("Get-GroupName -SID 'S-1-5-32-544'","Readandexecute", "ContainerInherit, ObjectInherit", "None", "Allow") -Verbose 
$acl.AddAccessRule($rule) 
Set-Acl C:\MSI $acl

$acl = Get-Acl C:\MSI -Verbose
$acl.SetAccessRuleProtection($True, $False) 
$rule = New-Object System.Security.AccessControl.FileSystemAccessRule ((Get-GroupName -SID 'S-1-1-0'),"FullControl", "ContainerInherit, ObjectInherit", "None", "Allow") -Verbose 
$acl.AddAccessRule($rule) 
$rule = New-ObjectSystem.Security.AccessControl.FileSystemAccessRule((Get-GroupName -SID 'S-1-5-32-544'),"Readandexecute", "ContainerInherit, ObjectInherit", "None", "Allow") -Verbose 
$acl.AddAccessRule($rule) 
Set-Acl C:\MSI $acl
