How do I pass multiple parameters into a function in PowerShell?
parameter-passing, powershell, syntax
Solution
Parameters in calls to functions in PowerShell (all versions) are space-separated, not comma separated. Also, the parentheses are entirely unneccessary and will cause a parse error in PowerShell 2.0 (or later) if `Set-StrictMode` `-Version 2` or higher is active. Parenthesised arguments are used in .NET methods only.
function foo($a, $b, $c) {
"a: $a; b: $b; c: $c"
}
ps> foo 1 2 3
a: 1; b: 2; c: 3
Problem
If I have a function which accepts more than one string parameter, the first parameter seems to get all the data assigned to it, and remaining parameters are passed in as empty. A quick test script: ``` Function Test([string]$arg1, [string]$arg2) { Write-Host "`$arg1 value: $arg1" Write-Host "`$arg2 value: $arg2" } Test("ABC", "DEF") ``` The output generated is ``` $arg1 value: ABC DEF $arg2 value: ``` The correct output should be: ``` $arg1 value: ABC $arg2 value: DEF ``` This seems to be consistent between v1 and v2 on multiple machines, so obviously, I'm doing something wrong. Can anyone point out exactly what?
