I am trying to use parseexact , however the dates that I have are in multiple formats. I tried
$format =@('yyMMddHHmm')
[System.DateTime]::ParseExact('1605221412',$format,$null)
and everything is fine When I try to add another format I get an exception
$format =@('yyMMddHHmm', 'yyyyMMddHHmm')
[System.DateTime]::ParseExact('1605221412',$format,$null,[System.Globalization.DateTimeStyles]::None)
I tried double quotes, writing inline , various ways of trying to pass an array as the second argument.
[System.DateTime]::ParseExact('1605221412','yyMMddHHmm, yyyyMMddHHmm',$null,[System.Globalization.DateTimeStyles]::None)
What am I missing ? Is it possible to use ParseExact for multiple formats without doing a bunch of if, then , else statements ?

You are doing it just fine, the only problem is that @(..) is object[] not string[]:
$datesToTest = '1605221412', '09/02/2022', '02-09-2022'
$formats = 'yyMMddHHmm', 'yyyyMMddHHmm', 'dd/MM/yyyy', 'dd-MM-yyyy'
$datesToTest | ForEach-Object {
[System.DateTime]::ParseExact($_, [string[]]$formats, [cultureinfo]::InvariantCulture)
}
