How to return output as enum in powershell v3 ?

I am using following function to find out whether the release is Major ,Patch or Invalid.

Function Compare-Version {

    [cmdletBinding()]
    Param (

        [version] $old,
        [Version] $New

    )

        If ( $New -le $Old  ) { return "Invalid" }
        ElseIf ( $new.Major -eq $Old.Major -And $New.Minor -gt $Old.Minor ) { return "Patch" }
        ElseIf ($new -gt $old) { return "Major" }

}

$TypeOfRelease = Compare-Version -Old "245.1" -New "246.1"

If ($TypeOfRelease -eq "Invalid" ) { "No operation"}
ElseIf ($TypeOfRelease -eq "Major") {"Change guid to support migration"}
Elseif ($TypeOfRelease -eq "Point") {"Just change the version don't upgrade GUID")

I hope enum can be of right choice rather than string. How to send enum as output result and compare it in powershell

In PowerShell v5 you will be able to declare enums directly e.g.:

enum VersionCompare { Invalid; Major; Patch }

In v3 you will need to use Add-Type e.g.:

PS> Add-Type -TypeDefinition 'public enum VersionCompare { Invalid, Major, Patch }'
PS> [VersionCompare]::Invalid
Invalid
