RunSpace06 – kodexempel

Här är källkoden för Runspace06-exemplet som beskrivs i Configuring a Runspace Using a Windows PowerShell Snap-in. Det här exempelprogrammet skapar ett runspace baserat på Windows PowerShell snapin-modulen, som sedan används för att köra en pipeline med ett enda kommando. För att göra detta skapar programmet konfigurationsinformationen för runspace, skapar ett runspace, skapar en pipeline med ett enda kommando och kör sedan pipelinen.
