Runspace06 サンプル

このサンプルでは 、System.Management.Automation.Runspaces.Initialsessionstate オブジェクトにモジュールを追加して、実行空間を開いた時点でモジュールが読み込まれる方法を示します。 モジュールには、System.Management.Automation.Powershellオブジェクトを使用して同期的に実行される Get-Proc コマンドレット(GetProcessSample02サンプルで定義) が提供されます。

必要条件

このサンプルでは、Windows PowerShell 2.0 が必要です。

対象

このサンプルでは、次の例を示します。

このサンプルでは 、System.Management.Automation.Runspaces.Initialsessionstate オブジェクトを使用して、実行空間を開く際に使用できる要素を定義する実行空間を作成します。 このサンプルでは、初期セッション状態に Get-Procを定義するモジュールが追加されます。
