In a previous tip you learned how PropertySets can create groups of properties for easier access. Yet another (hidden) feature of PowerShell objects is MemberSets. Objects can contain a MemberSet called PSStandardMembers which normally is hidden (along with a number of other MemberSets):
PS> Get-Process | Get-Member -MemberType MemberSet PS> Get-Process | Get-Member -MemberType MemberSet -Force TypeName: System.Diagnostics.Process Name MemberType Definition ---- ---------- ---------- psadapted MemberSet psadapted {BasePriority, ExitCode, HasExited, ExitTime, H... psbase MemberSet psbase {BasePriority, ExitCode, HasExited, ExitTime, Hand... psextended MemberSet psextended {__NounName, Name, Handles, VM, WS, PM, NPM, P... psobject MemberSet psobject {BaseObject, Members, Properties, Methods, Immed... PSStandardMembers MemberSet PSStandardMembers {DefaultDisplayPropertySet}
PSStandardMembers controls the standard fallback properties that PowerShell displays. This line lists the default properties for service objects returned by Get-Service:
PS> Get-Service | Select-Object -First 1 |
ForEach-Object { $_.PSStandardMembers.DefaultDisplayPropertySet.ReferencedPropertyNames } Status Name DisplayName
