Esempio di Runspace06Runspace06 Sample

Questo esempio illustra come aggiungere un modulo a un oggetto System.Management.Automation.Runspaces.Initialsessionstate in modo che il modulo venga caricato all'apertura di spazio.This sample shows how to add a module to an System.Management.Automation.Runspaces.Initialsessionstate object so that the module is loaded when the runspace is opened. Il modulo fornisce un cmdlet Get-proc (definito dall' esempio GetProcessSample02) che viene eseguito in modo sincrono tramite un oggetto System. Management. Automation. PowerShell .The module provides a Get-Proc cmdlet (defined by the GetProcessSample02 Sample) that is run synchronously by using a System.Management.Automation.Powershell object.

RequisitiRequirements

Questo esempio richiede Windows PowerShell 2,0.This sample requires Windows PowerShell 2.0.

EsempioExample

Questo esempio crea un spazio che usa un oggetto System.Management.Automation.Runspaces.Initialsessionstate per definire gli elementi disponibili quando viene aperto il spazio.This sample creates a runspace that uses an System.Management.Automation.Runspaces.Initialsessionstate object to define the elements that are available when the runspace is opened. In questo esempio un modulo che definisce un cmdlet Get-proc viene aggiunto allo stato della sessione iniziale.In this sample, a module that defines a Get-Proc cmdlet is added to the initial session state.
