比较字符串数组并在与 Out-GridView 匹配时显示结果?

[英]Comparing array of strings and display the result when matched to Out-GridView?

如何获得结果,以便已在 AllowedSenderDomains 中列出的用户电子邮件地址显示在 UserEmailDomainAlreadyRegistered 数组中,以便我可以输出到 OGV?

$UserEmailDomainAlreadyRegistered = # If the user email domain is found in the $AllowedSenderDomains, then display it in OGV

$AllowedSenders = @('User.Name@domain.com', 'User2.Name2@domain.net', 'User3.Name3@domain.net','unique.user@email.com')
    
$AllowedSenderDomains = @('domain.net', 'domain.com')

上面的预期结果是:

'User.Name@domain.com'
'User2.Name2@domain.net'
'User3.Name3@domain.net'

更新代码:

$policyName = '*'
$policy = Get-HostedContentFilterPolicy -Identity $PolicyName

$AllowedSenderDomains = $Policy.'AllowedSenderDomains' | Select-Object -ExpandProperty Domain -Unique
$AllowedSenders = $Policy.'AllowedSenders' | Select-Object Sender

$allowedDomains = '@({0})$' -f (($AllowedSenderDomains | ForEach-Object { [regex]::Escape($_) }) -join '|')
$AllowedSenders | Where-Object { $_ -match $allowedDomains } | OGV

$AllowedSenders | Where-Object { $AllowedSenderDomains -contains ($_ -split '@')[-1] } | OGV

上面两个OGV都显示空内容?

$AllowedSenderDomains
Domain1.com
Domain2.net
Domain3.org

$AllowedSenders
User1@domain1.com
User2@domain2.net
User3@Domain3.org

只需使用where-object commandlet 过滤掉您不想要的域:

# ~> $AllowedSenders | Where-Object { $_.Substring($_.LastIndexOf('@')+1) -in $AllowedSenderDomains}
User.Name@domain.com
User2.Name2@domain.net
User3.Name3@domain.net

另一种方法是使用正则表达式,尽管只有两个允许的域,这可能是矫枉过正:

$AllowedSenderDomains = 'domain.net', 'domain.com'
$AllowedSenders       = 'User.Name@domain.com', 'User2.Name2@domain.net', 'User3.Name3@domain.net','unique.user@email.com'

# create a regex from the allowed domains by joining them with OR (|)
# the regex is preceeded by the AT sign (@) and anchored to the end of the string with '$'
$allowedDomains = '@({0})$' -f (($AllowedSenderDomains | ForEach-Object { [regex]::Escape($_)}) -join '|')
# next, use -match to get only the emailaddresses that match the regex
$AllowedSenders | Where-Object { $_ -match $allowedDomains }

您也可以使用-split作为另一种选择,如下所示:

$AllowedSenders | Where-Object { $AllowedSenderDomains -contains ($_ -split '@')[-1] }

结果

User.Name@domain.com
User2.Name2@domain.net
User3.Name3@domain.net
