如何在powershell("user:mary@contoso.com:rwx，default:user:mary@contoso.com:rwx")中实现两值字符串的参数化

$originalString = 'user:mary@contoso.com:rwx,default:user:mary@contoso.com:rwx'
$splitString = $originalString.Split(',')
$userInfo = $splitString[0]
$permissionInfo = $splitString[1]

$userParams = $userInfo.Split(':')
$username = $userParams[1]
$email = $userParams[2]

$permissionParams = $permissionInfo.Split(':')
$defaultPermission = $permissionParams[2]

Write-Host "用户名: $username"
Write-Host "邮箱地址: $email"
Write-Host "默认权限: $defaultPermission"

用户名: mary@contoso.com
邮箱地址: rwx
默认权限: rwx
