Hi I want to check whether an string exist or start in set of array.
Example:
$str = "iit.apple"
$arr = ("apple", "mango", "grapes")
I want to check whether an array (arr) element matches or exist or starts with in string
I have tried using foreach loop to read each element but when matches found I am trying to break the loop.
Use the intrinsic .Where() method in First mode:
$str = "iit.apple"
$arr = ("apple", "mango", "grapes")
$anyMatches = $arr.Where({$str -like "*$_*"}, 'First').Count -gt 0
If any of the strings in $arr is a substring of $str, the Where(..) method will return a collection consisting of just that one element - so Where(...).Count -gt 0 will evaluate to $true
I would use regex and three "or" patterns.
'iit.apple' -match 'apple|mango|grapes'
True
Or
$str -match ($arr -join '|')
True
Or select-string takes an array of patterns:
$arr = "apple", "mango", "grapes"
$str | select-string $arr
iit.apple
To complement Mathias's answer here is how you do it with a foreach loop:
$str = "iit.apple"
$arr = "apple", "mango", "grapes"
$result = foreach($element in $arr) {
if($str -like "*$element*") {
$true
break
}
}
[bool] $result
Enumerable.Any can work too:
$delegate = [System.Func[object, bool]] {
$str -like "*$($args[0])*"
}
[System.Linq.Enumerable]::Any($arr, $delegate)
foreachloop) ?
