Foreach-Object with HashTables?

Question

I'm trying to check wheter some network drives are mapped via logon script. If they're not mapped, the script should be able to map them but My Foreach-Object in the code below doesn't work. why? Can't I use it on hashtables?

$Hash = @{
    "h:" = "\\server\share";
    "i:" = "\\server\share";
    "j:" = "\\server\share";
    "k:" = "\\server\share";
    "p:" = "\\server\share";
    "z:" = "\\server\share";
    }
        $Hash | ForEach-Object
        {
            If (!(Test-Path $_.Name))
            {
                $map = new-object -ComObject WScript.Network
                $map.MapNetworkDrive($_.Name, $_.Value, $true)
                Write-Host "Mapped That Stuff"
            }
            else
            {Write-Host ($Hash.Name) + ($Hash.Value)}
        }

How do I have to use foreach in this situation? Or is there a better way to solve this issue instead of a hashtable or a foreach loop?

To iterate over a [hashtable] you need to get an enumerator for it:

   $Hash.GetEnumerator() | ForEach-Object {
        If (!(Test-Path $_.Name))
        {
            $map = new-object -ComObject WScript.Network
            $map.MapNetworkDrive($_.Name, $_.Value, $true)
            Write-Host "Mapped That Stuff"
        }
        else
        {Write-Host ($_.Name) + ($_.Value)}
    }
