Powershell中的“处于”状态

Question

Is there any "in" condition in Powershell similar to sql. if available please let me know the syntax on how to use it. My senario is i need to get a list of ids and use it in another query.

Looking for doing below

//Below line i veried returns values more than 1
$desktopGroupIds = Get-BrokerDesktopGroup -AdminAddress 'IPAddressgoeshere' |  select uid

Get-BrokerPrivateDesktop  -AdminAddress 'IPAddressgoeshere' | Where { $desktopGroupIds.contains($_.DesktopGroupUid) } | select DesktopGroupUid

The 2nd query does not return value. i am sure the 2nd query can give results if i pass values one by one. i want to use may be '-in' operator if avaliable or make the above contains work.

Thanks,

Answer 1

-in is a reverse -contains operator that's been added in PowerShell 3.0 (so dasari.. has to update to use it). With contains you use $array -contains -element , while in PS3.0 you can use $element -in $array

You seem to have a typo in $desktopGroupIdS -c contains $_ ..... . Try this:

//Below line i veried returns values more than 1
$desktopGroupIds = @(Get-BrokerDesktopGroup -AdminAddress 'IPAddressgoeshere' |  select uid)

Get-BrokerPrivateDesktop  -AdminAddress 'IPAddressgoeshere' | Where { $desktopGroupIds -contains $_.DesktopGroupUid } | select DesktopGroupUid

Powershell's "in" keyword is normally used for selecting items individually in a collection object.

eg:

foreach($item in $collection)
{
    #...Process some code...
}

If you want to use "Contains" like you have in your solution, you can cast everything in $desktopGroupIds into an array by placing the first line inside @():

eg

//Below line i veried returns values more than 1
$desktopGroupIds = @(Get-BrokerDesktopGroup -AdminAddress 'IPAddressgoeshere' |  select uid)
Get-BrokerPrivateDesktop  -AdminAddress 'IPAddressgoeshere' | Where { $desktopGroupIds.Contains($_.DesktopGroupUid) } | select DesktopGroupUid

edit

Another solution you might try is using the -match operator:

eg:

$desktopGroupIds = @(Get-BrokerDesktopGroup -AdminAddress 'IPAddressgoeshere' |  select uid)
Get-BrokerPrivateDesktop  -AdminAddress 'IPAddressgoeshere' | Where { $desktopGroupIds -match $_.DesktopGroupUid } | select DesktopGroupUid

Answer 3

The update code line to fix the issue is shown below

Get-BrokerPrivateDesktop  -AdminAddress $regionAddress | Where { $desktopGroupIds  -Contains $_.DesktopGroupUid } | select DesktopGroupUid

Note above the usage of "-Contains"
