PowerShell Object Count

Question

I'm using VMware PowerCLI to query for datastores that have a certain amount of freespace. The query could come back with nothing, just one, or more than one. I feel like there's got to be an easier way to check if it's one or more than one.

$ds = get-datastore | where {$_.FreeSapceGB -gt 50} | Sort-Object FreeSpaceGB -descending

I know to check if I get results with this

if ($ds)

I know this will check if there's more than one

if ($ds.Count)

If there is more than one, I want to use the one with the most freespace so I use the first one

$ds[0]

But if there is only one, $ds[0] does not work and I have to use just $ds, which makes for too much duplicate coding.

I know I can limit my results with

| Select -first 1

But without limiting the results is there an easier way to do this?

This should do it:

$ds = @(get-datastore | where {$_.FreeSapceGB -gt 50} | Sort-Object FreeSpaceGB -descending)

Then you should always be able to use $ds[0] as long as $ds.Count is greater than 0.
