我在使用Invoke-Command将switch -CleanFolders传递给函数时遇到了一些困难。我找到this，但我真的不知道如何实现它，因为它不是针对某个函数。
调用我的函数可以正常工作：
Delete-OldFiles $Target $OlderThanDays $Server -CleanFolders
Invoke-Command -ComputerName "$Server" -Authentication Credssp -Credential $Credentials -ScriptBlock ${Function:Delete-OldFiles} -ArgumentList ($Target, $OlderThanDays, $Server)
但这根本不起作用：
Invoke-Command -ComputerName "$Server" -Authentication Credssp -Credential $Credentials -ScriptBlock ${Function:Delete-OldFiles} -ArgumentList ($Target, $OlderThanDays, $Server, -CleanFolders)
完整脚本：
#__________________________________________________________________________________________________________________________________
$ImportFile = "S:\Input\Scheduled Task\Auto_Clean.csv"
$Password = cat "S:\Input\pwd.txt" | ConvertTo-SecureString -Force
$UserName = "domain\me"
#__________________________________________________________________________________________________________________________________
# Scriptblock for running the function in a job
$JobFunc = {
# Function that removes files older than x days in all subfolders
Function Delete-OldFiles {
<#
.SYNOPSIS
Script to delete files and folders older than x days
.DESCRIPTION
Remove files older than x days in all subfolders and write success and failure actions to the logfile in "\\DEUSTHEIDIT02\Log\Scheduled Task\Auto_Clean\".
By default, empty foldes will be left behind and not deleted.
.PARAMETER Target
The path that will be recusively scanned for old files
.PARAMETER OlderThanDays
Filter for age of file, entered in days. Use 0 for all files to be removed
.PARAMETER CleanFolders
If this switch is specified folders that are older than 'OlderThanDays' and are empty will be removed. Default behaviour of this script is to leave empty folders behind.
.EXAMPLE
Delete-OldFiles -Target "\\grouphc.net\bnl\DEPARTMENTS\Brussels\CBR\SHARE\Target" -OlderThanDays "10"
Delete-OldFiles "\\grouphc.net\bnl\DEPARTMENTS\Brussels\CBR\SHARE\Target" "10"
Delete-OldFiles "E:\DEPARTMENTS\CBR\SHARE\Target" "10"
Description:
Deletes all files older than 10 days in the Target folder and all of its subfolders and write success and failure to the log.
.EXAMPLE
Delete-OldFiles "\\grouphc.net\bnl\DEPARTMENTS\Brussels\CBR\SHARE\Target" "10" -CleanFolders
Description:
Deletes all files older than 10 days and all empty folders in the Target folder and all of its subfolders and write success and failure to the log.

感谢您的帮助。

试试这样：
$sb = {
function Delete-OldFiles {
#...
}
Delete-OldFiles $args[0] $args[1] $args[2] -CleanFolders:$args[3]
}
Invoke-Command -ComputerName $Server -Authentication Credssp `
-Credential $Credentials -ScriptBlock $sb `
-ArgumentList ($Target, $OlderThanDays, $Server, $true)
