Runspace04 샘플

이 샘플에서는 System.Management.Automation.PowerShell 클래스를 사용하여 명령을 실행하는 방법과 명령을 실행할 때 throw되는 종료 오류를 catch하는 방법을 보여 줍니다. 두 명령이 실행되고 마지막 명령이 유효하지 않은 매개 변수 인수를 전달합니다. 따라서 개체가 반환되지 않고 종료 오류가 throw됩니다.

요구 사항

이 샘플에는 Windows PowerShell 2.0이 필요합니다.

입증합니다

이 샘플에서는 다음을 보여 줍니다.

예시

이 샘플은 Windows PowerShell에서 제공하는 기본 Runspace에서 명령을 동기적으로 실행합니다. 마지막 명령은 유효하지 않은 매개 변수 인수가 명령에 전달되기 때문에 종료 오류를 throw합니다. 종료 오류가 트래핑되어 표시됩니다.
