Array.Find on powershell array

Question

How can I use the Array.Find method in powershell?

For example:

$a = 1,2,3,4,5
[Array]::Find($a, { args[0] -eq 3 })

gives

Answer 1

Another option would be using an ArrayList, which provides a Contains method:

PS C:\> [Collections.ArrayList]$a = 'a', 'b', 'c'
PS C:\> $a.Contains('b')
True
PS C:\> $a.Contains('d')
False

Or, as @Neolisk mentioned in the comments, you could use PowerShell's -contains operator:

PS C:\> $a = 'a', 'b', 'c'
PS C:\> $a -contains 'b'
True
PS C:\> $a -contains 'd'
False
