PowerShell objects clash with built in functions?

Question

I have a JSON object that I have pulled from an API, and I need to pull an IP address from it.

the data is stored in a variable looks like this :

echo $IPMIAddr

count next previous results                                                                                                    
----- ---- -------- -------                                                                                                    
    1               {@{id=17247; family=4; address=10.2.63.142/24; vrf=; tenant=; status=; role=; interface=; description=; ...

I can parse through the data using dots to get to what I want like this

echo $IPMIAddr.results


id            : 17247
family        : 4
address       : 10.2.63.142/24
vrf           : 
tenant        : 
status        : @{value=1; label=Active}
role          : 
interface     : @{id=50554; 
url=http://netbox/api/dcim/interfaces/50554/; device=; 
virtual_machine=; name=IPMI}
description   : 
nat_inside    : 
nat_outside   : 
custom_fields : 
created       : 2018-05-03
last_updated  : 2018-05-03T08:08:36.856098Z

So the next logical step would be:

echo $IPMIAddr.results.address

but when I do this i get the error :

OverloadDefinitions                                                                                        
-------------------                                                                                        
System.Object&, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 Address(int )

Because .address is a predefined function within PowerShell.

How do I get past this?

edit :

the result of:

Get-Member -InputObject $IPMIAddr

Answer 1

It looks like your .results member is actually an array, which contains a member named Address. You need to index into your array to access the proper member:

$IPMIaddr.results[0].address

The reason ForEach-Object works is due to enumeration:

$IPMIaddr.results | Foreach-Object -MemberName address

This pulls the address member off all the results objects.
