Adding string to variable powershell

Question

I am trying to create a powershell script that will append a character to my variable only if the variable is not null. For instance a user fills out a form, or spreadsheet cell in my case and it has data I want to append a | to that variable so when I call that variable in my script it will display | contents of variable. This is what I have and it does not seem to be working.

 if ([string]::IsNullOrEmpty($field6))
  {$field6 = $field6}
 else 
  {$field6 = "| $field6" }

  }
echo $field6

This should suffice:

if ($field6 -ne $null) { $field6 = "| $field6" }

You can even skip the explicit null check: if ($field6) { $field6 = "| $field6" }

@mousio That may yield undesired results, because there are other values than $null that will make if ($field6) evaluate to $false.
