This works:
Get-Command $PSCommandPath | %{ $_.Parameters }
But this doesn't:
Get-Command $PSCommandPath | %{ $_.Parameters | %{ echo $_.Value } }
Why?

I am confused on what you are trying to accomplish? You want to pipe the results into another where statement?Austin T French– Austin T French2013-12-26 14:33:03 +00:00Commented Dec 26, 2013 at 14:33

The Parameters property is a hash table (dictionary):
Get-Command $PSCommandPath | %{ $_.Parameters.GetType() }
IsPublic IsSerial Name BaseType
-------- -------- ---- --------
True True Dictionary`2 System.Object
The Powershell pipeline will automatically "unroll" arrays and collections, but not hash tables. If you want to foreachthrough the indivudual elements, you have to enumerate them expliclitly using .getenumerator().
Get-Command $PSCommandPath | %{ $_.Parameters.GetEnumerator() | % {echo $_.Value } }

Yea! almost there.. but this:
echo $_.Value.ToString() emits: System.Management.Automation.ParameterMetadata instead of the parameter string value.. how can I output the parameter's text?Tar
and ` %{ foreach($i in $_.Parameters.GetEnumerator()) { echo $i.Value.ToString() } }` gives the same:
System.Management.Automation.ParameterMetadata

Define "the parameter's text".

ok, got it:
Get-Command $PSCommandPath | %{ $_.Parameters.GetEnumerator() | % { (Get-Variable $_.Key).Value } }
