Runspace01 (VB.NET) – kodexempel

Här är kodexempel för det runspace som beskrivs i Skapa ett konsolprogram som kör ett angivet kommando. För att göra detta anropar programmet ett runspace och anropar sedan ett kommando. (Observera att det här programmet inte anger konfigurationsinformation för runspace och inte heller uttryckligen skapar en pipeline.) Kommandot som anropas är Get-Process cmdleten .
