I am trying to do some string concatenation/formatting, but it's putting all the parameters into the first placeholder.
Code
function CreateAppPoolScript([string]$AppPoolName, [string]$AppPoolUser, [string]$AppPoolPass) { # Command to create an IIS application pool $AppPoolScript = "cscript adsutil.vbs CREATE ""w3svc/AppPools/$AppPoolName"" IIsApplicationPool`n" $AppPoolScript += "cscript adsutil.vbs SET ""w3svc/AppPools/$AppPoolName/WamUserName"" ""$AppPoolUser""`n" $AppPoolScript += "cscript adsutil.vbs SET ""w3svc/AppPools/$AppPoolName/WamUserPass"" ""$AppPoolPass""`n" $AppPoolScript += "cscript adsutil.vbs SET ""w3svc/AppPools/$AppPoolName/AppPoolIdentityType"" 3" return $AppPoolScript } $s = CreateAppPoolScript("name", "user", "pass") write-host $s Output
cscript adsutil.vbs CREATE "w3svc/AppPools/name user pass" IIsApplicationPool cscript adsutil.vbs SET "w3svc/AppPools/name user pass/WamUserName" "" cscript adsutil.vbs SET "w3svc/AppPools/name user pass/WamUserPass" "" cscript adsutil.vbs SET "w3svc/AppPools/name user pass/AppPoolIdentityType" 3

Refer below PowerShell script for the above problem statement to pass multiple parameters to function in PowerShell. Write-Host $TempFile "file already exists!" Write-Host -f Green $TempFile "file created successfully!" Write-Host -f Green $FolderName "folder created successfully!"
You can pass the parameters in the PowerShell function and to catch those parameters, you need to use the arguments. Generally, when you use variables outside the function, you really don't need to pass the argument because the variable is itself a Public and can be accessible inside the function.
Note that when you are working with multiple parameters, the function call must have the same number of arguments as there are parameters, and the arguments must be passed in the same order.
Lose the parentheses and commas.
Calling your function as:
$s = CreateAppPoolScript "name" "user" "pass" gives:
cscript adsutil.vbs CREATE "w3svc/AppPools/name" IIsApplicationPool cscript adsutil.vbs SET "w3svc/AppPools/name/WamUserName" "user" cscript adsutil.vbs SET "w3svc/AppPools/name/WamUserPass" "pass" cscript adsutil.vbs SET "w3svc/AppPools/name/AppPoolIdentityType" 3 By the way, using a PowerShell here-string might make your function a little easier to read as well, since you won't need to double up all the "-marks:
function CreateAppPoolScript([string]$AppPoolName, [string]$AppPoolUser, [string]$AppPoolPass) { # Command to create an IIS application pool return @" cscript adsutil.vbs CREATE "w3svc/AppPools/$AppPoolName" IIsApplicationPool cscript adsutil.vbs SET "w3svc/AppPools/$AppPoolName/WamUserName" "$AppPoolUser" cscript adsutil.vbs SET "w3svc/AppPools/$AppPoolName/WamUserPass" "$AppPoolPass" cscript adsutil.vbs SET "w3svc/AppPools/$AppPoolName/AppPoolIdentityType" 3 "@ } If you love us?
