Get values of all the properties of an object

Lets say you want to list all properties of an object but you don't know all of them by name. Here is comming in help the Get-Member cmdlet. I find it very useful especially when working with new objects that I'm not familiar with.

I'm going to give an example with the list of network adapters listed from the WMI.

 So, lets list all of the members.

Get-Wmiobject Win32_NetworkAdapter | where { $_.Speed -ne $null -and $_.MACAddress -ne $null } | Get-Member

ConvertFromDateTime         ScriptMethod  System.Object ConvertFromDateTime();
ConvertToDateTime           ScriptMethod  System.Object ConvertToDateTime();

 We see that we have more than what we need - AliasProperty, Method, PropertySet, ScriptMethod. So We need to filter by Type:

Get-Member -Type Property

 Also we don't want to print the special properties in this case - starting with "__" so we add extra filter:

where { $_.Name -notmatch "^_" }

 Now we have all member properties filtered and we are ready to display them:

foreach { "$($_.Name): $($obj.$($_.Name))" }

 What we did is that we print the name of the property and right after that we print the value of the property. You might be wondering where this $obj came from. It is comming from a previous foreach loop in the pipeline:

foreach { $obj = $_; $_ | Get-Member -Type Property | where { $_.Name -notmatch "^_" } | foreach { "$($_.Name): $($obj.$($_.Name))" } }

 In the $obj we are saving the object of which we want to display all of the properties.

I added an extra part in the pipeline so we show only for one object not for all:

Select -First 1

 And here is the full example:

Get-Wmiobject Win32_NetworkAdapter | where { $_.Speed -ne $null -and $_.MACAddress -ne $null } | Select -First 1 | foreach { $obj = $_; $_ | Get-Member -Type Property | where { $_.Name -notmatch "^_" } | foreach { "$($_.Name): $($obj.$($_.Name))" } }
