Runspace05 샘플

이 샘플에서는 runspace를 열 때 스냅인의 cmdlet을 사용할 수 있도록 System.Management.Automation.Runspaces.InitialSessionState 개체에 스냅인을 추가하는 방법을 보여 줍니다. 스냅인은 System.Management.Automation.PowerShell 개체를 사용하여 동기적으로 실행되는 Get-Proc cmdlet(GetProcessSample01 샘플의해 정의됨)을 제공합니다.

요구 사항

이 샘플에는 Windows PowerShell 2.0이 필요합니다.

입증합니다

이 샘플에서는 다음을 보여 줍니다.

예시

이 샘플에서는 System.Management.Automation.Runspaces.InitialSessionState 개체를 사용하여 runspace를 열 때 사용할 수 있는 요소를 정의하는 runspace를 만듭니다. 이 샘플에서는 Get-Proc cmdlet을 정의하는 스냅인이 초기 세션 상태에 추가됩니다.
