Get-Member

Get the properties and methods of object(s).

Syntax
      Get-Member [ [-name] string[] ]  [-inputObject psobject]
        [-View {Extended | Adapted | Base | All}]
           [-memberType memberType] [-Force] [-static] [CommonParameters]

Key
   -name 
       The names of one or more properties or methods of the object.
       Get-Member gets only the specified properties and methods.
       If you use -Name parameter with -MemberType, -View, or -Static, Get-Member gets
       only the members that satisfy the criteria of all parameters. 
       To get a static member by name, use: -Static -Name

   -inputObject psobject
       The object(s) to retrieve information about.
		
   -memberType 
       Get only members with the specified member type. The default is All. 

         valid values: 

         AliasProperty         A property that defines a new name for an existing property.
         CodeMethod            A method that references a static method of a .NET Framework class.
         CodeProperty          A property that references a static property of a .NET Framework class.
         Event                 Indicates that the object sends a message to indicate an action or a change in state.
         MemberSet             A predefined collection of properties and methods, such as PSBase, PSObject, and PSTypeNames.
         Method                A method of the underlying .NET Framework object. 
         NoteProperty          A property with a static value.
         ParameterizedProperty A property that takes parameters and parameter values. 
         Property              A property of the underlying .NET Framework object.
         PropertySet           A predefined collection of object properties.
         ScriptMethod          A method whose value is the output of a script.
         ScriptProperty        A property whose value is the output of a script.
         All                   Get all member types.
         Methods               Get all types of methods of the object
                               (for example, Method, CodeMethod, ScriptMethod).
         Properties            Get all types of properties of the object
                               (for example, Property, CodeProperty, AliasProperty, ScriptProperty).

        Not all objects have every type of member. If you specify a member type that the object does not have, 
        PowerShell returns a null value.

        To get related types of members, such as all extended members, use the View parameter. 
        If -MemberType is combined with -Static or -View, Get-Member will get members that belong to both sets.

   -Static
       Get only the static properties and methods of the object. 
       Static properties and methods are defined on the class of objects, not on any
       particular instance of the class.

       If -Static is used with -View, the -View parameter is ignored.
       If -Static is used with -MemberType, Get-Member gets only the members that belong to both sets.

   -View PSMemberViewTypes
       Get only particular types of members (properties and methods).
       Specify one or more of the values. The default is "Adapted, Extended".

        Valid values are:
          Base      Get only the original properties and methods of the .NET Framework object
                    (without extension or adaptation).
          Adapted   Get only the properties and methods defined in the PowerShell extended type system.
          Extended  Get only the properties and methods that were added in the Types.ps1xml 
                    files or by using the Add-Member cmdlet.
          All       Get the members in the Base, Adapted, and Extended views.

       The -View parameter determines the members retrieved, not just the display of those members. 
       To get particular member types, such as script properties, use -MemberType.

       If you use -MemberType and -View in the same command, Get-Member gets the members that belong to both sets. 
       If you use -Static and -View  in the same command, the -View parameter is ignored.

   -Force
       Add the intrinsic members (PSBase, PSAdapted, PSObject, PSTypeNames)
       and the compiler-generated get_ and set_ methods to the display.
       By default, Get-Member gets these properties in all views other than "Base"
       and "Adapted," but it does not display them.

   CommonParameters:
       -Verbose, -Debug, -ErrorAction, -ErrorVariable, -WarningAction, -WarningVariable,
       -OutBuffer -OutVariable.

Standard Aliases for Get-Member: gm

Using the -InputObject parameter is not the same as piping an object to Get-Member:

- When a collection of objects are piped to Get-Member, Get-Member gets the members of the individual objects in the collection, such as the properties of the integers in an array of integers.

- When -InputObject is used to submit a collection of objects, Get-Member gets the members of the collection, such as the properties of the array in an array of integers.

Examples

Display the properties of a Process object:

PS C:\> get-process | get-member -MemberType property

Display the properties of an Alias object:

PS C:\> get-alias | get-member

Display the value of the PSBase property of the Schedule service:

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

Display the script properties of event log objects in the System log:

PS C:\> get-eventlog -log system | gm -membertype scriptproperty

Piping a command into get-member twice will display the properties of the parent object: PowerShell.Commands.MemberDefinition:

PS C:\> get-process | get-member | get-member

Prefixing the pipelined input with a comma will also force get-member to run against the container object:
PS C:\> $alias = get-alias
PS C:\> ,$alias | get-member
