Esempio di Runspace06

Questo esempio illustra come aggiungere un modulo a un oggetto System.Management.Automation.Runspaces.InitialSessionState in modo che il modulo venga caricato all'apertura dello spazio di esecuzione. Il modulo fornisce un cmdlet Get-Proc (definito dal GetProcessSample02 Sample) che viene eseguito in modo sincrono usando un oggetto System.Management.Automation.PowerShell.

Requisiti

Questo esempio richiede Windows PowerShell 2.0.

Dimostra

In questo esempio viene illustrato quanto segue.

Esempio

Questo esempio crea uno spazio di esecuzione che usa un oggetto System.Management.Automation.Runspaces.InitialSessionState per definire gli elementi disponibili all'apertura dello spazio di esecuzione. In questo esempio viene aggiunto un modulo che definisce un cmdlet Get-Proc allo stato iniziale della sessione.
