Runspace06 – exempel

Det här exemplet visar hur du lägger till en modul i ett System.Management.Automation.Runspaces.InitialSessionState objekt så att modulen läses in när körningsytan öppnas. Modulen innehåller en Get-Proc cmdlet (definierad av GetProcessSample02 Sample) som körs synkront med hjälp av ett System.Management.Automation.PowerShell-objekt.

Krav

Det här exemplet kräver Windows PowerShell 2.0.

Demonstrerar

Det här exemplet visar följande.

Exempel

Det här exemplet skapar ett runspace som använder ett System.Management.Automation.Runspaces.InitialSessionState-objekt för att definiera de element som är tillgängliga när runspace öppnas. I det här exemplet läggs en modul som definierar en Get-Proc cmdlet till i det inledande sessionstillståndet.
