Runspace05 – mintaRunspace05 Sample

Ez a minta bemutatja, hogyan adhat hozzá beépülő modult egy System.Management.Automation.Runspaces.Initialsessionstate objektumhoz, hogy a beépülő modul parancsmagja elérhető legyen a RunSpace megnyitásakor.This sample shows how to add a snap-in to an System.Management.Automation.Runspaces.Initialsessionstate object so that the cmdlet of the snap-in is available when the runspace is opened. A beépülő modul egy System. Management. Automation. PowerShell objektum használatával szinkronban futó Get-proc parancsmagot biztosít (amelyet a GetProcessSample01 mintahatároz meg).The snap-in provides a Get-Proc cmdlet (defined by the GetProcessSample01 Sample) that is run synchronously by using a System.Management.Automation.Powershell object.

KövetelményekRequirements

Ehhez a mintához Windows PowerShell 2,0 szükséges.This sample requires Windows PowerShell 2.0.

Útmutató ehhez:Demonstrates

Ez a példa a következőt mutatja be.This sample demonstrates the following.

PéldaExample

Ez a minta egy RunSpace hoz létre, amely egy System.Management.Automation.Runspaces.Initialsessionstate objektumot használ a RunSpace megnyitásakor elérhető elemek definiálásához.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. Ebben a példában egy Get-proc parancsmagot definiáló beépülő modul lesz hozzáadva a kezdeti munkamenet-állapothoz.In this sample, a snap-in that defines a Get-Proc cmdlet is added to the initial session state.
