Powershell PSCustomObject Extracting values - powershell

Question

When creating and working with PSCustomObjects which result in a NoteProperty member with a 'Definition' (as shown below), is there any easy, programmatic way to select the values from the definition fields without resorting to splitting the strings?
For example below, is there a 'good' way to extract the value 'silver' from the field of name 'token' that does not requre traditional string manipulations? I've been messing around with select and -ExpandProperty but getting no-where fast and would appreciate a nudge in the right direction.
TypeName: System.Management.Automation.PSCustomObject
Name MemberType Definition
---- ---------- ----------
bsw NoteProperty decimal bsw=3.14
name NoteProperty string name=chris
token NoteProperty string token=silver
volume NoteProperty decimal volume=17.22
Thanks.
Update: Following guidance from Thomas I came up with this function to extract Noteproperty members from a PSObject and return a Hashtable with the names of the fields and the values:
function convertObjectToHash($psObj) {
$hashBack = #{}
try {
$psObjFieldNames = $psObj | get-member -type NoteProperty | select "Name"
$psObjFieldNames | foreach-object {
$hashBack.Add($_.Name,$psObj.$($_.Name)) }
}catch{ "Error: $_" }
return $hashBack
}
Thanks!

You can access the members of a custom object like in any other object:
$myCustomObject.token
Reproduction:
$myCustomObject = New-Object -TypeName psobject
$myCustomObject | Add-Member -MemberType NoteProperty -Name bsw -Value 3.14
$myCustomObject | Add-Member -MemberType NoteProperty -Name name -Value "chris"
$myCustomObject | Add-Member -MemberType NoteProperty -Name token -Value "silver"
$myCustomObject | Add-Member -MemberType NoteProperty -Name volume -Value 17.22
$myCustomObject | Get-Member -MemberType NoteProperty
$myCustomObject.token
Output:
TypeName: System.Management.Automation.PSCustomObject
Name MemberType Definition
---- ---------- ----------
bsw NoteProperty System.Double bsw=3.14
name NoteProperty string name=chris
token NoteProperty string token=silver
volume NoteProperty System.Double volume=17.22
silver

Since in your objects you store a string value, I see no other way to extract just the value silver then to use a string method to get only the part after the equals sign.
($obj.token -split '=', 2)[-1] --> silver
Why not create the custom objects with an extra property called value and add the value you seek in there, taken from the Definition property? like
$obj = [PsCustomObject]#{'token' = 'string token=silver'; 'value' = 'silver'}
