The Get-TypeData cmdlet gets the extended type data in the current session. This includes type data that was added to the session by Types.ps1xml file and dynamic type data
that was added by using the parameter of the Update-TypeData cmdlet.

You can use the extended type data that Get-TypeData returns to examine the type data in the session and send it to the Update-TypeData and Remove-TypeData cmdlets.

Extended type data adds properties and methods to objects in Windows PowerShell. You can use the added properties and methods in the same ways that you would use the
properties and methods that are defined in the object type. However, when writing scripts, be aware that the added properties and methods might not be present in every
Windows PowerShell session.

For more information about Types.ps1xml files, see about_Types.ps1xml (http://go.microsoft.com/fwlink/?LinkID=113274). For more information about dynamic type data that the
Update-TypeData cmdlet adds, see Update-TypeData.

This cmdlet is introduced in Windows PowerShell 3.0.

Example 1

PS C:\>Get-TypeData

This command gets all extended type data in the current session.

Example 2

PS C:\>"*Eventing*" | Get-TypeData
TypeName Members--------
-------System.Diagnostics.Eventing.Reader.EventLogConfiguration {}System.Diagnostics.Eventing.Reader.EventLogRecord
{}System.Diagnostics.Eventing.Reader.ProviderMetadata {[ProviderName, System.Management.Automation.Runspaces.AliasProper...

This command gets all types in the current session that have names that contain "Eventing".


PS C:\>(Get-TypeData *EventLogEntry*).Members.EventID
GetScriptBlock SetScriptBlock IsHidden Name

-------------- -------------- -------- ----
$this.get_EventID() -band 0xFFFF False EventID

This command gets the script block that creates the value of the EventID property of EventLogEntry objects.

Example 3

PS C:\>(Get-TypeData -TypeName System.DateTime).Members["DateTime"].GetScriptBlock
if ((& { Set-StrictMode -Version 1; $this.DisplayHint }) -ieq "Date")
"{0}" -f $this.ToLongDateString()
elseif ((& { Set-StrictMode -Version 1; $this.DisplayHint }) -ieq "Time")
"{0}" -f $this.ToLongTimeString()
"{0} {1}" -f $this.ToLongDateString(), $this.ToLongTimeString()

This command gets the script block that defines the DateTime property of System.DateTime objects in Windows PowerShell.

The command uses the Get-TypeData cmdlet to get the extended type data for the System.DataTime type. The command gets the Members property of the TypeData object.

The Members property contains a hash table of properties and methods that are defined by extended type data. Each key in the Members hash table is a property or method name
and each value is the definition of the property or method value.

The command gets the DateTime key in Members and its GetScriptBlock property value.

The output shows the script block that creates the value of the DateTime property of every System.DateTime object in Windows PowerShell.

Example 4

PS C:\>dir $pshome\*types.ps1xml -Recurse | Select-String "EventLogEntry"

This command finds the Types.ps1xml file that added extended type data for the EventLogEntry type to the session. This command uses the Get-ChildItem cmdlet (alias = "dir")
to perform a recursive search for Types.ps1xml files in the Windows PowerShell installation directory ($pshome) and its subdirectories. The command sends the Types.ps1xml
files to the Select-String cmdlet, which does a full-text search for the "EventLogEntry" type name in the files and returns the matches.
