如何匹配 PowerShell 中的字符串

Question

I'm trying to match a string in PowerShell, but I can't get True.

"one.two" -match "One Two"
False

Ok, maybe I gave too limited information of my problem.

So here is a bit more information. I have this code:

$userRoles = @('User', 'Customer Support');
$adGroups = @('ad.group.user', 'ad.group.customer.admin');
$userRoleToAdGroup = @{};
foreach ($userRole in $userRoles) {
    $adGroupsMatch = @($adGroups -match "$userRole")
    $userRoleToAdGroup.Add($userRole, $adGroupsMatch)
}
$userRoleToAdGroup

And the output value is empty for "Customer Support".

Answer 1

Here the space between "One" and "Two" will match literally "One Two". If you want to match any character between them use:

"one.two" -match "One.Two"

Here in Regex . means any character. Or you can append

* = 0 or more instances of previous charcter
+ = 1 or more instances of previous charcter
? = 0 or 1 instances of previous charcter
\w = match any word
\d = match any digit
\s = match any whitespace
{n,m} = match n to m instances of previous charcter

Answer 2

I don't exactly understand what you are trying to achieve but you should take a look at PowerShell syntax and the -match operator.

Matching a role name like Customer Support is really just matching the same exact string when using regex. One way to make this match like a wildcard would be

$String = "Customer Support"
$MatchString = "($($String -replace '\s+', '|'))"
'ad.group.customer.admin' -match $MatchString
True

This code is spliting any spaces in $String and combines them in a legit regex query "(Customer|Support)" .

NOTE

This code will match any string with the word "customer" and / or "support" in it.

'ad.group.user.support' -match $MatchString
True
