Applies To: Windows PowerShell

Assembly:  System.Management.Automation (in System.Management.Automation.dll)

public abstract void Close()

Exception Condition

The runspace is not in a state that allows it to be closed.


The runspace failed to close a remote session.

For runspaces that are using nested pipelines, this method closes all active pipelines.

To find out the state of the runspace, use the RunspaceStateInfo property.

To close a namespace asynchronously, call the CloseAsync method.

For more information about runspaces and runspace pools, see Host Application Runspaces.


The user at the command line may not necessarily realize that the commands that Windows PowerShell runs are being processed within a runspace. From the command-line user’s point of view, commands are run in a Windows PowerShell session. From a host application’s point of view, commands are run within a runspace.
