Powershell Test if array in one line
There are type operators one can use to test the type of a variable. -is is the one you need. Like so,
$foo = @() # Array$bar = "zof" # String$foo -is [array] # Is foo an array?True # Yes it is$foo -is [string] # Is foo a string?False # No it is not$bar -is [array] # How about barFalse # Nope, not an array$bar -is [string] # A string then?True # You betcha!So something like this could beused
if($csv -is [array]) { # Stuff for array} else { # Stuff for string}
Instead of doing:
$csv = (gc $FileIn)you had to
$csv = @(gc $FileIn)Now the output will always be an array of strings irrespective of the file having one line or not. The rest of the code will just have to treat $csv as an array of strings. This way is better than having to check if the output is an array etc., at the least in this situation.
