DESCRIPTION


The Get-Member cmdlet gets the "members" (properties and methods) of objects.


To specify the object, use the InputObject parameter or pipe an object to Get-Member. To retrieve information about static members (members of the class, not of the
instance), use the Static parameter. To get only certain types of members, such as NoteProperties, use the MemberType parameter.

CanPauseAndContinue Property System.Boolean CanPauseAndContinue {get;}
CanShutdown Property System.Boolean CanShutdown {get;}
CanStop Property System.Boolean CanStop {get;}
Container Property System.ComponentModel.IContainer Container {get;}
DependentServices Property System.ServiceProcess.ServiceController[] DependentServices {get;}
DisplayName Property System.String DisplayName {get;set;}
MachineName Property System.String MachineName {get;set;}
ServiceHandle Property System.Runtime.InteropServices.SafeHandle ServiceHandle {get;}
ServiceName Property System.String ServiceName {get;set;}
ServicesDependedOn Property System.ServiceProcess.ServiceController[] ServicesDependedOn {get;}
ServiceType Property System.ServiceProcess.ServiceType ServiceType {get;}
Site Property System.ComponentModel.ISite Site {get;set;}
Status Property System.ServiceProcess.ServiceControllerStatus Status {get;}



This command displays the properties and methods of the process objects (System.ServiceProcess.ServiceController) that are generated by the Get-Service cmdlet.

The command uses the pipeline operator (|) to send the output of a Get-Service command to Get-Member.

Because the Get-Member part of the command does not have any parameters, it uses all of the default values. As such, it gets all member types, but it does not get static
members and does not display intrinsic members.










-------------------------- EXAMPLE 2 --------------------------

PS C:\>get-service | get-member -force
PS C:\>(get-service -schedule).psbase



This example gets all of the members (properties and methods) of the service objects (System.ServiceProcess.ServiceController) retrieved by the Get-Service cmdlet, including
the intrinsic members, such as PSBase and PSObject, and the get_ and set_ methods.

The first command uses the Get-Service cmdlet to get objects that represent the services on the system. It uses a pipeline operator (|) to pass the service objects to the
Get-Member cmdlet.

The Get-Member command uses the Force parameter to add the intrinsic members and compiler-generated members of the objects to the display. Get-Member gets these members, but
it hides them by default.

You can use these properties and methods in the same way that you would use an adapted method of the object. The second command shows how to display the value of the PSBase
property of the Schedule service.










-------------------------- EXAMPLE 3 --------------------------

PS C:\>get-service| get-member -view extended
TypeName: System.ServiceProcess.ServiceController

Name MemberType Definition
---- ---------- ----------
Name AliasProperty Name = ServiceName



This command gets the methods and properties of service objects that were extended by using the Types.ps1xml file or the Add-Member cmdlet.

The Get-Member command uses the View parameter to get only the extended members of the service objects. In this case, the extended member is the Name property, which is an
alias property of the ServiceName property.










-------------------------- EXAMPLE 4 --------------------------

PS C:\>get-eventlog -log system | gm -membertype scriptproperty
TypeName: System.Diagnostics.EventLogEntry

Name MemberType Definition
---- ---------- ----------
EventID ScriptProperty System.Object EventID {get=$this.get_EventID() -band 0xFFFF;}



This command gets the script properties of event log objects in the System log in Event Viewer. In this case, the only script property is the EventID.










-------------------------- EXAMPLE 5 --------------------------

PS C:\>get-eventlog -log system | get-member -membertype scriptproperty
TypeName: System.Diagnostics.EventLogEntry

Name MemberType Definition
---- ---------- ----------
EventID ScriptProperty System.Object EventID {get=$this.get_EventID() -band 0xFFFF;}



This command gets the script properties of event log objects in the System log in Event Viewer.

The command uses the MemberType parameter to get only objects with a value of AliasProperty for their MemberType property.

The command returns the EventID property of the EventLog object.










-------------------------- EXAMPLE 6 --------------------------

PS C:\>$a = "get-process", "get-service", "get-culture", "get-psdrive", "get-executionpolicy"
PS C:\>foreach ($cmdlet in $a) {invoke-command $cmdlet | get-member -name machinename}
TypeName: System.Diagnostics.Process

Name MemberType Definition
---- ---------- ----------
MachineName Property System.String MachineName {get;}

TypeName: System.ServiceProcess.ServiceController

Name MemberType Definition
---- ---------- ----------
MachineName Property System.String MachineName {get;set;}



This command gets objects that have a MachineName property from a list of cmdlets.

The first command stores the names of several cmdlets in the $a variable.

The second command uses a ForEach statement to invoke each command, send the results to Get-Member, and limit the results from Get-Member to members that have the name
"MachineName."

The results show that only process objects (System.Diagnostics.Process) and service objects (System.ServiceProcess.ServiceController) have a MachineName property.










-------------------------- EXAMPLE 7 --------------------------

PS C:\>$a = get-member -inputobject @(1)
PS C:\>$a.count
1
PS C:\>$a = get-member -inputobject 1,2,3
TypeName: System.Object[]

Name MemberType Definition
---- ---------- ----------
Count AliasProperty Count = Length
Address Method System.Object& Address(Int32 )
Clone Method System.Object Clone()
...
PS C:\>$a.count
1



This example demonstrates how to find the properties and methods of an array of objects when you have only one object of the given type.

Because the goal of the command is to find the properties of an array, the first command uses the InputObject parameter. It uses the "at" symbol (@) to indicate an array. In
this case, the array contains only one object, the integer 1.

The third command uses the Get-Member cmdlet to get the properties and methods of an array of integers, and the command saves them in the $a variable.

The fourth command uses the Count property of the array to find the number of objects in the $a variable.










-------------------------- EXAMPLE 8 --------------------------

PS C:\>$file = get-item c:\test\textFile.txt
PS C:\>$file.psobject.properties | where-object {$_.issettable} | format-table -property name

PS C:\>[appdomain]::CurrentDomain.GetAssemblies() | foreach-object { $_.getexportedtypes() } | foreach-object {$_.getproperties() | where-object {$_.canwrite }} |
select-object reflectedtype, name



This example shows how to determine which properties of an object can be changed. The example uses a file, but you can use this command format to find the changeable
properties of any object in Windows PowerShell.

The first command uses the Get-Item cmdlet to get a text file, and then it saves the file object in the $file variable.

The second command gets all of the changeable properties of the file object in the $file variable and displays the names of the properties in a table.

The third command gets the changeable properties of all objects in your Windows PowerShell session.










-------------------------- EXAMPLE 9 --------------------------

PS C:\>$s = get-service
PS C:\>$s | get-member
TypeName: System.ServiceProcess.ServiceController

Name MemberType Definition
---- ---------- ----------
Name AliasProperty Name = ServiceName
RequiredServices AliasProperty RequiredServices = ServicesDependedOn
Disposed Event System.EventHandler Disposed(System.Object, System.EventArgs
Close Method System.Void Close()
Continue Method System.Void Continue()
CreateObjRef Method System.Runtime.Remoting.ObjRef CreateObjRef(type requestedTy
Dispose Method System.Void Dispose()
...
PS C:\>get-member -inputObject $s
TypeName: System.Object[]

Name MemberType Definition
---- ---------- ----------
Count AliasProperty Count = Length
Address Method System.Object&, mscorlib, Version=2.0.0.0, Cultu
Clone Method System.Object Clone()
CopyTo Method System.Void CopyTo(array array, int index), Syst
Equals Method bool Equals(System.Object obj)
Get Method System.Object Get(int )
GetEnumerator Method System.Collections.IEnumerator GetEnumerator()
GetHashCode Method int GetHashCode()
...



This example shows how the InputObject parameter works in the Get-Member cmdlet. When you use the InputObject parameter to get the members of a collection, Get-Member gets
the members of the collection. When you pipe a collection of objects to Get-Member, Get-Member gets the members of each item in the collection.

The first command gets the services on the local computer and saves the services in the $s variable.

The second command pipes the $s variable to the Get-Member cmdlet. Get-Member gets the types of each member of $s and the members of that type. In this case, it gets
ServiceController objects and lists the members, such as RequiredServices and Close.

The third command uses the InputObject parameter of Get-Member to submit the $s variable. Get-Member gets the type (System.Object[]) and the members of the collection (or
"array") of ServiceController objects, such as Count and Clone.
