Runspace10 샘플

이 샘플에서는 기본 초기 세션 상태를 만드는 방법, System.Management.Automation.Runspaces.InitialSessionStatecmdlet을 추가하는 방법, 초기 세션 상태를 사용하는 Runspace를 만드는 방법 및 System.Management.Automation.PowerShell 개체를 사용하여 명령을 실행하는 방법을 보여 줍니다.

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 호스트 애플리케이션에서 정의한 Get-Proc cmdlet이 초기 세션 상태에 추가되고 System.Management.Automation.PowerShell 개체를 사용하여 cmdlet이 동기적으로 실행됩니다.
