How to remove item from an array in PowerShell (v5.1) - powershell

Question

I have an array of elements in PowerShell (v5.1) as below.
I want to remove the item with matching condition EmpId=102
$testData = #(
#{ Name='ABC'; EmpId=100 },
#{ Name='EFG'; EmpId=101 },
#{ Name='XYZ'; EmpId=102 }
);
Is there any simple way to achieve this?
maybe something like $testData.Remove($testData.Find("EmpId == 102")) ?

Answer 1

if your array is really a collection of one-item hashtables, then the following otta work ... [grin] it pipes the collection thru the Where-Object cmdlet & filters out anything item that has the value-to-exclude in the EmpId key value.
$TestData = #(
#{ Name='ABC'; EmpId=100 }
#{ Name='EFG'; EmpId=101 }
#{ Name='XYZ'; EmpId=102 }
)
$EmpId_ToExclude = 102
$TestData |
Where-Object {
$_['EmpId'] -ne $EmpId_ToExclude
}
output ...
Name Value
---- -----
EmpId 100
Name ABC
EmpId 101
Name EFG
note that the items are not required to be in order ... that is how hashtables work if you don't specify [ordered].

I hope this info is some use. Maybe you can use an arraylist. You don't need #( ) to make an array.
[collections.arraylist]$testData = #{ Name='ABC'; EmpId=100 },
#{ Name='EFG'; EmpId=101 },
#{ Name='XYZ'; EmpId=102 }
$a = $testdata[1]
$testdata.remove($a)
Or
$testdata.removeat(1)
Unfortunely, this doesn't work. I guess you would need a pointer to the hashtable:
$testdata.remove(#{ Name='XYZ'; EmpId=102 })
Actually, it would be easy with a single hashtable:
$testData = #{ 'ABC'=100
'EFG'=101
'XYZ'=102 }
$testdata.remove('xyz')
$testdata
Name Value
---- -----
ABC 100
EFG 101
