How to concat path and file name for creation and removal

Question

I'm trying the following.

$woohoo = "c:\temp\shabang"
New-Item -ItemType File $woohoo

This creates a file at desired location. However, I'd like to split the $woo and $hoo and go something like this.

$woo = "c:\temp"
$hoo = "shabang"
New-Item -ItemType File ($woo + $hoo)

This doesn't work and I need a hint on how to make it fly. This suggestion nor this on worked out when applied to my situation. Apparently - given path format is unsupported.

Suggestions?

Edit

This is what it looks like:

Edit 2

$woo = "c:\temp"; $hoo= "shabang"; New-Item -ItemType File (Join-Path $woo $hoo)

Solution

$path=Get-Location 
$file="myfile.json"
$path=Join-Path $path $file

#you can cast to a class if the class definition is known
$results = (Get-Content -Path $path  | Out-String | ConvertFrom-Json)

foreach($tempObj in $results)
{
   $obj_vals=$tempObj|Select-Object -Property *
   Write-Host $obj_vals  -ForegroundColor Green
}
