====== New line in PowerShell string ======
Append "`n" to the end of the string.
Or use the following function
<code powershell |AppendNewLine>
function AppendNewLine {
    $tmpData += $args[0] + $args[1]
    $tmpData += "`n"
    return $tmpData
}
$string += AppendNewLine "Parameter" "Value"
$string += AppendNewLine "Parameter1" "Value1"
